Thus, the existing drilling field operation has the following problems: ① The number of sensors of the drilling machine is small, the degree of electronization is poor, part of driller operation tables still use mechanical pointer instruments to display parameters, and the monitoring and evaluation effects on the drilling state are poor; ② The existing drilling machine has low automation level, all mechanized operations need drillers and drillers to perform manual operation, the operation level and efficiency fluctuation are large (for example, driller tripping speed control of different well groups and single unloading speed difference of drillers are large, and the time of drilling is directly caused to affect the final drilling cost in different ways) seriously depending on the experience of field personnel; ③ Frequent personnel update and flow, frequent operation violations, unreasonable instructions and poor optimization degree of drilling operation occur when new personnel experience is insufficient; ④ The informatization/digitalization degree is poor, post coordination and instruction issuing are still carried out in a mode of interphone shouting, and the situation of the prior drilling is not known clearly after the driller shifts to work; ⑤ The lack of sharing of the block and the drilling data of the adjacent wells causes that the site engineers and the drilling supervision are not aware of the block condition, the optimization selection of the drilling parameters is lack of reference, the potential risk assessment of the drilling is insufficient, and the handling measures of the sudden risk are unreasonable; ⑥ The massive drilling data in the block and the annual operation data of the drilling company are not excavated and applied, and the support for optimizing the drilling parameters of the target well, early warning the drilling risk, handling the risk and improving the operation efficiency is lacking; ⑦ The parameter abnormality and early risk sign of the drilling site need to depend on driller, logging and engineer 24 hours uninterrupted manual monitoring, long-time continuous work is difficult to keep high concentration of attention, and when personnel experience is insufficient and fatigue is missed, complex drilling situation or risk identification/treatment is not timely, which usually causes risk aggravation and even casualties.
With the development and application of informatization, big data, artificial intelligence and other technologies, the automatic intelligent drilling technology and system become core elements of petroleum drilling, so that the efficiency of petroleum drilling can be enhanced, manual operation errors can be reduced, real-time drilling optimization can be realized, the operation cost can be reduced, and production accidents can be controlled. In carrying out the invention, however, the inventors have found that: the existing technical scheme related to intelligent drilling is either biased to automatic control of drilling equipment, unsuitable for current drilling site application, or biased to some aspect of drilling parameter optimization or risk early warning, and lacks effective support for digitization of the current drilling site.
Accordingly, in order to solve one or more of the above technical problems, the present application proposes a driller's intelligent auxiliary system for drilling which is applicable to both the old drilling machine on the current drilling site and the future automatic intelligent drilling machine. The system comprises: the data bus control module is in butt joint with the well site drilling rig; the well site server is in communication connection with the drilling machine system through the data bus control module, and is used for collecting site measurement data acquired by the drilling machine system in real time in the drilling process, comprehensively deciding the state of the well and the operation change trend through mining preset database data based on the site measurement data, and converting the current comprehensive decision result into a drilling operation instruction in a first system mode (when the first type drilling machine is docked), so that the drilling machine system performs automatic joint control on an automatic drilling machine required by the current operation according to the current instruction, and drilling operation in the current mode is realized; and a plurality of terminals for implementing communication with each other through the wellsite server, wherein the plurality of terminals are configured to receive and share the comprehensive decision result obtained from the wellsite server, and in a second system mode (when the second type of drilling machine is docked), obtain a drilling operation instruction issued according to the current comprehensive decision result, and at this time, operate a conventional drilling machine managed by a terminal person associated with the current drilling operation according to the currently obtained instruction by the person, thereby implementing the drilling operation in the current mode. In the first system mode, the terminal acquires and displays drilling operation instructions which are automatically executed according to the current comprehensive decision result so as to be monitored by terminal personnel related to the current drilling operation.
Therefore, the intelligent driller auxiliary system for the drilling well site provided by the invention can be independently deployed at the well site of an old drilling machine so as to be suitable for the old drilling machine, and can be used by embedding the drilling machine system into an automatic intelligent drilling machine so as to be suitable for a novel automatic intelligent drilling machine, thereby effectively helping drilling personnel to realize the optimization of drilling operation parameters, avoid potential risks and control and process sudden complex situations, and finally completing safe and efficient drilling operation.
Fig. 1 is a schematic diagram of the overall structure of a driller intelligent auxiliary system according to an embodiment of the present application. As shown in fig. 1, the driller intelligent auxiliary system according to the embodiment of the application at least includes: a wellsite server 20, a data bus control module 10, and a plurality of terminals 30.
In the embodiment of the present invention, the terminal 30 is an interactive device that integrates functions of user command communication, data recording, information referencing, and/or risk prompt display configured for each wellsite personnel in the wellsite, such as a wellsite supervision, an engineer, and a driller. The terminal 30 includes, but is not limited to: an explosion-proof mobile phone terminal, an explosion-proof flat terminal, a computer terminal, an integrated machine terminal, an intelligent helmet, other intelligent wearing prompt equipment and the like. Various terminals can be loaded with different operating systems including windows, android, apple IOS and the like.
Referring to fig. 1, wellsite server 20 is connected to a wellsite drilling rig (rig model 1,2 … … N) via a bus. Wherein the data bus control module 10 interfaces with the control system of the wellsite drilling rig. Further, the wellsite server 20 communicates with the wellsite drilling rig via the data bus control module 10. The wellsite drilling rig control system interfacing with the data bus control module 10 in embodiments of the present invention may be a control system of an automated rig (first type of rig) or a control system of a conventional rig (second type of rig).
When the drilling machine and the wellsite server 20 are connected and installed, the wellsite server 20 communicates with the drilling machine through the data bus control module 10 and automatically identifies the type of the drilling machine. Wherein, when the wellsite server 20 recognizes that the drilling machine connected with the wellsite server is an automatic intelligent novel drilling machine, the operation mode of the current auxiliary system is set to a first type system mode (namely, a docking mode with the first type drilling machine); when wellsite server 20 recognizes that the drilling rig to which it is connected is a conventional drilling rig, the operational mode of the current auxiliary system is set to a second type of system mode (i.e., a docking mode with the second type of drilling rig).
According to the invention, various drilling machine (automatic or traditional) control systems are docked through the data bus control module 10, so that not only are measurement data on the drilling machine obtained from the drilling machine or control instructions transmitted to the drilling machine control system; meanwhile, sensing measurement data of other various ground and underground tools/equipment are also transmitted to the well site server 20 through the data bus control module 10, and the data bus control module 10 converts various control instructions sent by the well site server 20 according to communication standards of different tools/equipment and then sends the converted control instructions as drilling operation instructions. The communication protocol of the data bus control module 10 can be flexibly extended according to the tool/device/drilling machine to be docked.
The wellsite server 20 communicates with the wellsite drilling rig via the data bus control module 10. The wellsite server 20 is configured to collect field measurement data collected by the wellsite drilling rig in real time during a drilling process, and comprehensively decide a current well state and a current drilling operation change trend through model calculation analysis and mining of preset database data based on a drilling operation analysis model system carried by the wellsite server 20 according to the field measurement data collected by the wellsite drilling rig in real time, so as to obtain a corresponding comprehensive decision result. Wherein the field measurement data includes: logging data, drilling data and rig operating state data fed back in real time by each rig. The database data includes: the field measurement data and historical risk disposition case data recorded by each adjacent well (historic well) when performing each historic drilling operation, and geological information and engineering information about the present well (e.g., well bore structure, drilling process, drilling tool assembly, etc.).
After generating the comprehensive decision result based on the drilling operation analysis model system, the wellsite server 20 is further configured to convert the current comprehensive decision result into a drilling operation command in the first system mode, and send the currently generated drilling operation command to the wellsite drilling machine required for the current operation through the data bus control module 10, so as to jointly control each equipment of the automated drilling machine related to the current drilling operation (drilling machine equipment required for implementing the drilling operation of the current drilling operation type) according to the decision-based drilling operation command, thereby implementing the current drilling operation in an automated manner.
In addition, in the embodiment of the present invention, the communication between the plurality of terminals 30 is also implemented by the wellsite server 20. The plurality of terminals 30 are configured to receive and share the analysis system-based integrated decision results generated by the wellsite server 20 to present current integrated decision results to wellsite personnel at each terminal 30 to provide cues and references to the respective wellsite personnel. In the second class of system modes, wellsite server 20 does not perform conversion of the work orders based on the currently generated composite decision results. At this time, in the second system mode, after the current comprehensive decision result pushed by the wellsite server 20 is displayed to the wellsite personnel corresponding to the terminal 30, the wellsite personnel realizes the instruction communication based on the referenced current comprehensive decision result through the communication between the terminals, and inputs the latest well drilling operation instruction which is well communicated to the corresponding terminal 30. Thus, the terminal 30 is further configured to obtain drilling operation instructions including drilling operation type instructions and/or drilling operation parameter setting information, which are issued according to the current comprehensive decision result, so that a terminal person associated with the current drilling operation (for example, if the current drilling operation type is a drilling operation, the terminal person of the drilling machine associated with the drilling operation is determined) operates corresponding conventional drilling equipment (for example, a mud pump, a winch, a top drive, etc.) managed by the person according to the currently inputted drilling operation instructions, thereby implementing the current drilling operation in a big data decision manner. Wherein the drilling operation instruction at least comprises: the type of the current drilling operation, the drilling equipment (used for selecting controlled objects) related to the type of the current drilling operation, and the drilling control parameters and control action instructions (used for realizing the running control of the drilling equipment) of each controlled drilling equipment. In practice, wellsite drilling includes a variety of rig equipment, such as: winch, top drive, mud pump, iron driller, automatic catwalk, etc.
In addition, the driller intelligent auxiliary system according to the embodiment of the invention further comprises: cloud center 50. Cloud center 50 communicates with wellsite servers 20. The cloud center 50 is mainly used for performing background management, enhancement analysis and information interaction on information such as field measurement data corresponding to different drilling operations corresponding to all wells, final comprehensive decision results, drilling operation instructions corresponding to the decision results and the like. In addition, the cloud center 50 is used as a background management center of the whole well site, and can communicate with the plurality of terminals 30 through a well site network, so that command communication and interaction between each terminal personnel and background personnel can be realized.
Fig. 2 is a schematic diagram of a specific architecture of a driller intelligent auxiliary system according to an embodiment of the present application. As shown in fig. 2, the wellsite server 2-1 is used for loading a database, running a background data service and an algorithm service of a driller intelligent auxiliary system, supporting the system to display at the front ends of various terminals (including but not limited to mobile phones, tablets, integrated machines, computers, intelligent helmets and various intelligent wearable devices, system types include windows, android, apple IOS and the like), and interacting data, algorithm service, management/operation instructions with the rear Fang Yun center 2-8 through a network. When the old drilling machine is used in a well site, the well site server 2-1 only receives various data of the drilling machine and the well site through the data bus control module 2-7, performs data monitoring and well drilling parameter calculation and analysis, then pushes early warning and optimization results (comprehensive decision results) to front-end equipment of well site personnel for reference display, and inputs a well drilling operation instruction through the front-end equipment by the well site personnel, so that the current instruction is applied under the operation of related personnel; when the automated intelligent drilling machine airport is used, the well site server 2-1 further sends the optimization/decision result of the system back to the drilling machine through the data bus control module 2-7 in the form of control instructions to automatically execute corresponding operations.
The explosion-proof mobile phone terminal 2-2, the explosion-proof flat panel terminal 2-3, the computer 2-4, the explosion-proof intelligent auxiliary integrated machine 2-5 and the like are used for running a front-end software interface of a driller intelligent auxiliary system, receiving various monitoring, calculating, early warning and optimizing data pushed by the well site server 2-1 and providing operation modules such as visual interaction analysis, alarm prompt, instruction issuing, voice communication, drilling machine control and the like for each terminal user. The explosion-proof mobile phone terminal 2-2, the explosion-proof flat panel terminal 2-3 and the computer 2-4 are respectively used for the mobile and fixed office demands of personnel such as well site supervision, drilling engineers and the like. In addition, the explosion-proof intelligent auxiliary integrated machine 2-5 is arranged in a driller room of a drilling platform to provide fixed application for the driller of the drilling well, and furthermore, the explosion-proof intelligent auxiliary integrated machine 2-5 can be additionally provided with an acousto-optic alarm lamp to provide visual and clear alarm prompt for the driller.
In addition, the driller intelligent auxiliary system provided by the embodiment of the invention further comprises earphone equipment. Further, each terminal 30 is also used to identify instructions and/or messages issued by the terminal personnel regarding voice-based modalities. The earphone equipment adopts the explosion-proof Bluetooth earphone 2-6, and the explosion-proof Bluetooth earphone 2-6 can provide convenient voice interaction functions for each terminal user, so that communication in a well site and intelligent voice control on a system are realized.
Fig. 3 is a schematic diagram of the software functions in the driller's intelligent auxiliary system according to an embodiment of the present application. In the embodiment of the present application, each terminal device is further equipped with a voice assistant 1-01 and a related module of a voice call 1-02 (refer to fig. 3). The voice assistant 1-01 can recognize voice instructions of a drilling user by using a built-in voice recognition model, call various functional modules in the wellsite server 20 according to the user instructions, provide multiple functions such as quick information inquiry, data entry, equipment control and the like for the user, and support instruction expansion after the user develops and customizes the front-end man-machine interaction functional module and the application, so that voice control is realized. The voice call 1-02 can utilize the built-in audio conference control to realize the whole-person call communication function among well site personnel such as well site supervision, engineers, driller and the like, and replace the communication mode of using interphone to call at the current well site. In addition, after the user (terminal person) logs in the terminal 30, the voice call is in the answering state by default and the microphone is in the off state, so that the environmental noise of the user without speaking can be avoided; and after the microphone is opened, the user can realize the broadcasting call function and can also carry out call communication with the login user of each terminal of the system.
Each terminal device is further equipped with a related module for issuing 1-05 of operation instructions based on communication (refer to fig. 3). The well site operation instruction of the existing system is that an engineer tells a driller through an interphone, the driller controls a drilling machine to operate according to the instruction, and various issued instructions are issued, but the issuing mode is unreasonable, namely the traced evaluation cannot be realized. The operation command issuing 1-05 module in the embodiment of the invention can provide a command record capable of tracking back for a well site, a well site supervision/engineer issues interface input command types (including but not limited to drilling, tripping, drilling, circulation, reaming and the like) and specific drilling machine control parameter ranges (such as parameters of drilling weight, rotating speed, displacement and the like given during drilling operation) under the command issuing of a system terminal, after determining to send, a new input command appears in a popup window form at a driller terminal and prompts a driller to confirm in combination with an audible and visual alarm, at the moment, a confirmation command and a new drilling operation command corresponding to the confirmation command are generated, after the driller confirms that the command is received, the terminal of a command issuing person can prompt that the command is received, and all drilling operation commands for realizing final drilling machine control are stored in a database of a well site server, so that the command is conveniently traced back during drilling and after drilling.
The data bus control module 2-7 is provided with various data communication interfaces, can be connected with various drilling machine control systems and drilling machine measuring tools and/or equipment in the well site, and is responsible for converging various measuring data (including but not limited to ground drilling machine data, downhole tool data, logging data and the like) of the well site and transmitting the converging and returning data to the well site server 2-1. Further, when the automatic intelligent drilling machine well site is applied, the data bus control module 2-7 is responsible for transmitting various control instructions (drilling operation instructions) of the well site server 2-1 to corresponding drilling machine equipment and tools, so that automatic control of operation is realized. In addition, by utilizing the intelligent well site data buses in the data bus control modules 2-7, the driller intelligent auxiliary system can flexibly dock automatic intelligent drilling machines with different models and different communication standards with various well site data acquisition tools/equipment, and can realize quick docking and control of novel drilling machines/equipment/tools by expanding the communication standards in the buses.
Further, in order to incorporate expert auditing mechanisms in the first class of system modes based on automation, embodiments of the present invention divide the first class of system modes described above (the operational mode of the current driller's assistance system in the case of interfacing with the first class of drilling rigs) into two classes, including: intelligent operation mode and passive supervision mode. In the intelligent operation mode, the wellsite server 20 is further configured to record a currently generated comprehensive decision result, and directly convert the current comprehensive decision result into a drilling operation instruction, thereby implementing a fully-automatic drilling operation instruction, and completing control of the automated drilling machine.
In the passive supervision mode, the wellsite server 20 is further configured to push the current comprehensive decision result to each terminal, and obtain a confirmation instruction (obtained after the reference and instruction communication of the current comprehensive decision result by each wellsite specialist) about the current comprehensive decision result, so as to maintain or adjust the current comprehensive decision result according to the current confirmation instruction, thereby converting the new comprehensive decision result into a drilling operation instruction, and recording the new comprehensive decision result and the corresponding drilling operation instruction. When the confirmation instruction does not change the comprehensive decision result obtained on the basis of the analysis system, the current comprehensive decision result is kept according to the current confirmation instruction, and then the current comprehensive decision result is converted into a drilling operation instruction; when the confirmation instruction changes the recommended information related to the drilling machine control in the comprehensive decision result obtained based on the analysis system, the current comprehensive decision result is adjusted according to the change information indicated in the current confirmation instruction, and a new comprehensive decision result is generated, so that the current new comprehensive decision result is converted into a drilling operation instruction.
In the second system mode, the wellsite server 20 is further configured to receive and record drilling operation instructions including drilling operation type instructions and/or drilling machine operation parameter setting information entered via communication session interactions between the terminals 30, for verification.
More specifically, in the embodiment of the present invention, the wellsite server 20 is further configured to mine the database data by using related modules related to the following drilling operation analysis model system, and obtain, according to the field measurement data collected in real time, a monitoring result (including a calculation result of a current drilling parameter) including the field measurement data, and/or a prediction result of a variation trend of various drilling parameters, and/or a detection result of an abnormal parameter, and/or a specific drilling operation procedure prompt result, and/or a drilling risk identification and prediction result, and/or a key event prompt result, and/or an adjacent well risk prompt result, and/or a comprehensive decision result including a drilling parameter and drilling process recommendation information, and/or a risk treatment strategy generation result, which are related to the present well.
Specifically, referring to fig. 3, the drilling operation analysis model system in the wellsite server 20 according to the embodiment of the present invention is equipped with relevant modules (refer to fig. 3) for real-time monitoring of data 1-03, wellsite data record 1-04, command overrun prompt 1-08, operation rule prompt 1-09, critical event prompt 1-10, drilling risk alarm 1-11, parameter anomaly early warning 1-12, adjacent well risk prompt 1-13, parameter process recommendation 1-14, risk intelligent treatment 1-15, etc., so as to utilize these relevant modules to make comprehensive decisions including state monitoring, risk prediction and prompt, process recommendation, control strategy recommendation, etc., for the current drilling operation process, and obtain corresponding comprehensive decision results. The comprehensive decision result comprises generation results corresponding to various related modules participating in the comprehensive decision.
The data real-time monitoring 1-03 can collect various parameter data (i.e. field measurement data) of the well site received by the auxiliary system and parameter calculation results (including but not limited to well temperature, pressure, friction torque distribution, cuttings migration condition and the like) based on the field measurement data in real time and display the parameter data at the terminal 30, so that well site personnel can conveniently grasp drilling machine, shaft and operation state in real time.
The well site data records 1-04 can provide digital records for various drilling operations (events) in the well site, support logging labels including comprehensive decision results of the key events of the well, drilling fluid measurement data, inclinometry data, operation programs, risk treatment schemes, effects and the like, final drilling operation instructions corresponding to the comprehensive decision results, and real-time acquired site measurement data. In addition, the wellsite data recording module 1-04 can also add or delete corresponding recording items according to the user requirements through the terminal so as to realize customization of the recording items. In addition, the user may further utilize a voice assistant to enable rapid and accurate recording and/or customization of corresponding numbers and text.
When the traditional old drilling machine well site is applied, the command overrun prompt 1-08 can prompt the parameters which do not meet the requirements by actively monitoring whether the driller operation parameters (namely, detecting on-site measurement data) meet the requirements of the commands issued to the drilling machine system (for example, when drilling operation, whether the weight on bit, the rotating speed and the displacement are in the numerical range of the command requirements) according to the executed operation commands issued in real time, so that the strict execution of the drilling operation commands is ensured. In addition, the command overrun prompt 1-08 can also be applied to an automatic intelligent drilling machine well site so as to dynamically monitor the execution condition of drilling operation commands generated based on analysis system decisions.
When the traditional old drilling machine well site is applied, the operation procedure prompt 1-09 can be based on preset drilling construction operation procedure requirements, on-site measurement data collected in real time according to the data real-time monitoring 1-03 are generated, key operation procedure information (specific drilling operation procedure prompt results) used for prompting terminal personnel to observe is used for prompting drillers to observe the operation procedure (for example, pump-on circulation is carried out every 1000 meters in the drilling process) in the drilling operation process in time by utilizing the key operation procedure information, the problems that current drilling well site personnel update flow frequently, operation violations frequently occur due to insufficient experience of new personnel are solved, and the new drillers are helped to quickly reach the qualified driller operation standard.
The key event prompt 1-10 is used for marking the depth position point of the historical event which occurs in the well drilling process, and generating a corresponding prompt result in time when the depth position point is close to the marked point (namely, the key event prompt result is not generated when a drill bit passes through the unmarked depth point), so that the problem that an engineer/driller can know the condition of the previous shift well drilling clearly after daily shift (for example, when a drill string is blocked at a certain well depth), the prompt is sent when the drilling operation approaches the marked point again, and complex situations or risks caused by misoperations (for example, when the driller starting speed of a shift is too fast, the pipe string is easy to be blocked directly when the driller is blocked at the previous shift, and the drilling jam occurs) can be solved.
The well drilling risk alarm 1-11 is used for continuously monitoring risks occurring in the well drilling operation process and predicting potential risks in real time (7 x 24 hours) according to field measurement data collected in real time by utilizing a risk identification and prediction algorithm in the system, and generating corresponding well drilling risk identification and prediction results when the potential risks are predicted and/or well drilling risks are currently generated, so as to prompt personnel on the well drilling field, thereby timely controlling or avoiding or eliminating the risks and avoiding accidents caused by aggravation of the risks. Therefore, the problems of aggravation of risks and even casualties caused by untimely identification/treatment of complex drilling situations or risks when the current well site depends on manual monitoring, and the personnel experience is insufficient or fatigue and omission occur due to high concentration of attention due to long-time continuous work are solved.
The parameter anomaly early warning 1-12 is used for monitoring anomalies of various parameters (such as sudden drop of outlet flow, continuous drop of total pool volume of drilling fluid and the like) in real time based on real-time monitoring data and calculation data (field measurement data collected in real time) by utilizing methods such as trend discrimination and the like in a system, generating prediction results of various corresponding drilling parameter variation trends and/or detection results of the anomaly parameters, and timely prompting drilling personnel to check reasons for the occurrence of parameter anomalies (such as whether the current anomalies are caused by drilling operation procedures or underground anomalies), so that the drilling personnel can be treated in early stages of risk occurrence symptoms, and the formation of risks is avoided.
The adjacent well risk prompt 1-13 is used for prompting the risks that the adjacent wells beside the present well occur at the adjacent depth positions in real time according to database data in the implementation process of drilling operation, so as to generate corresponding prompt results (namely, the adjacent well risk prompt results are timely generated when the adjacent well risk prompt results are close to the positions where the adjacent well risks occur, and the adjacent well risk prompt result information is not generated when the drill bit passes through the depth positions where the adjacent well risks do not occur), so that drilling personnel can adjust drilling process/parameters in advance and form corresponding treatment plans, the same risks are avoided occurring in the present well, or timely and effective treatment can be carried out after the risks inevitably occur.
The parameter process recommendation 1-14 is used for analyzing the application relation of different stratum drilling parameters in the current block and matching the drilling process based on the block where the own well is and the drilling history data of the adjacent well in the database data by adopting a data mining algorithm, combining the engineering design information of the own well, determining the optimal drilling process (including but not limited to a well structure, a drilling tool combination and the like) aiming at the own well through matching of similar adjacent wells, and completing multidimensional optimization (including but not limited to drilling pressure, rotating speed, displacement and the like) of the drilling parameters through a particle swarm algorithm/genetic algorithm and other machine learning algorithms, thereby generating the drilling parameters and the drilling process recommendation information. Thus, when the current modules 1-14 are used for single deployment application at the old drilling rig well site, the well site server 20 is used for pushing the optimized recommendation results of the drilling parameters and the drilling process to each terminal 30 so as to provide reference for drilling personnel and apply the reference; when the automatic intelligent drilling machine well site embedded drilling machine control system is applied, the well site server 20 is utilized to directly convert the well drilling parameters and the optimized recommended results of the drilling process into control instructions to execute the drilling operation.
The risk intelligent treatment 1-15 is used for screening and determining a risk treatment scheme aiming at the current abnormality or potential risk or risk by utilizing a risk treatment scheme analysis model based on blocks in database data and adjacent well drilling history risk treatment case data under the condition that the abnormality, occurrence risk or potential risk is detected/predicted by the drilling risk alarm 1-11 and/or parameter abnormality early warning 1-12, so as to generate corresponding risk treatment strategy information (such as drilling parameter adjustment, perforation, leakage stoppage and the like). When the old drilling rig wellsite is deployed and applied independently, the risk treatment strategy information is pushed to each terminal 30 by using the wellsite server 20 to provide reference for drilling personnel and apply the risk treatment strategy information; when the automatic intelligent drilling machine well site embedded drilling machine control system is applied, the risk treatment strategy information can be directly converted into a control instruction by using the well site server 20 to execute corresponding drilling operation, so that corresponding drilling risks are controlled, eliminated and avoided.
The wellsite server 20 of the present embodiment is also equipped with functional modules related to application pattern recognition 1-16, rig equipment control 1-17, system management 1-18, database 1-19, drilling design review 1-06, and adjacent well history review 1-07 (see fig. 3).
The rig apparatus controls 1-17 are used to convert the currently generated comprehensive decision results into drilling operation instructions based on analytical model decisions when the auxiliary system is applied to an automated intelligent rig wellsite. Specifically, the rig apparatus controls 1-17 are further configured to generate drilling operation instructions including instructions for adjusting and setting operation parameters of rig apparatuses such as winches, top drives, mud pumps, etc., and instructions for controlling operation of different rig apparatuses such as automatic catwalks, iron drills, automatic pipe racking machines, etc., according to drilling parameters and drilling process recommended information, so as to achieve the purpose of controlling drilling parameters (including, but not limited to, weight on bit, rotational speed, displacement, etc.), and the purpose of switching different drilling operation links (but not limited to, tripping, tapping, etc.).
Further, the system management 1-18 is used for setting and managing the types of drilling machines, drilling construction regulations of a foundation, all critical thresholds for detecting risks and parameter anomalies, data and algorithm services, user permission ranges of auxiliary systems, cloud center servers and the like.
Further, the databases 1-19 are used for storing all the database data, all the comprehensive decision data of the adjacent wells and the own well, and the final drilling operation instructions corresponding to the comprehensive decision data of all the adjacent wells and the own well. For example: all relevant historical drilling data of the adjacent well, various real-time/static data of the well, calculation analysis data of the system, early warning optimization results and the like.
Further, since the existing drilling site is mostly paper for supervision, engineers, drilling team, logging team to review, and the situation of damage and insufficient number of design report correction often occurs, in order to solve this problem, in the embodiment of the present invention, a module for 1-06 of drilling design review is provided in the wellsite server 20, and the module is used for providing online drilling design review for each user of the wellsite through access to the wellsite server 20 by each terminal 30 in the system. Thus, the foregoing problems are avoided, and when the embedded automatic drilling machine executes the intelligent operation mode, the parameter process recommendations 1-14 are automatically based on the drilling design, and the well bore meeting the drilling design requirement is drilled through intelligent drilling operation.
Further, the adjacent well history review 1-07 is used to provide an adjacent well Shi Zaixian review for a driller of a traditional old drilling rig well site through access of each terminal 30 to the well site server 20, thereby helping him to learn information such as regional geology, drilling problems, treatment, drilling process use effects, etc., so as to make an optimal decision according to the actual situation of the well during the drilling process. In addition, when the automatic drilling machine well site is used, an adjacent well Shi Shuju is formed according to the current comprehensive decision result and the corresponding final drilling operation instruction, and is used as a case to help a system to perform process/parameter optimization, risk coping treatment and other optimizing bases so as to update and optimize algorithm models related to drilling risk alarm 1-11, parameter abnormality early warning 1-12, parameter process recommendation 1-14 and risk intelligent treatment 1-15, thereby realizing continuous optimization of intelligent decisions of drilling operation.
In addition, the application mode 1-16 modules in the embodiment of the invention are used for identifying or selecting one of the three modes of 'single deployment mode', 'intelligent operation mode' and 'passive supervision mode' for application. The system provides data, information, an optimization result and operation advice for field personnel, and does not butt the control system of any drilling machine equipment; the intelligent operation mode and the passive supervision mode are suitable for the automatic intelligent drilling machine well site, and the system is connected to a control system of drilling machine equipment. Under an intelligent operation mode, the system takes a built-in drilling procedure and the operation performance range of drilling machine equipment as a limiting domain, analyzes the state of the well and predicts the change trend through real-time calculation, excavates mass data of a historical well to form an optimized drilling operation instruction, and sends the optimized drilling operation instruction to a PLC control system of an automatic intelligent drilling machine through an intelligent well site data bus of the system, and the control equipment automatically completes various operation operations, so that the optimization of drilling operation parameters, the avoidance of potential risks and the control treatment of sudden complex conditions are realized, and finally the safe and efficient drilling operation is completed; in a passive supervision mode, all optimized drilling operation instructions of the system are required to be finally confirmed by at least one person in well site personnel such as drillers, engineers, supervision and the like and then sent to an automatic intelligent drilling machine for execution, and the drillers, engineers, supervision, rear experts and the like can adjust and/or modify the operation instructions according to the requirements, at the moment, the system becomes a portable and flexible semi-automatic control platform, and under personnel supervision control, the drilling operation parameter optimization, potential risk avoidance, sudden control processing complex conditions are realized, and finally safe and efficient drilling operation is completed.
It should be noted that, in order to ensure that the decision mechanism of the expert or professional of the system is flexible, in the embodiment of the present invention, a corresponding switching mechanism is also configured for the intelligent operation mode in the well site. Specifically, wellsite server 20 is further configured to switch the intelligent operation mode to the passive supervision mode upon receiving an overrun cut-off command sent by terminal 30. In this way, in the intelligent operation mode, the on-site monitoring personnel can overrun the intelligent operation mode of the cut-off system at any time to switch into the passive supervision mode.
In addition, in order to improve the feasibility and operability of the drilling operation instructions, in embodiments of the present invention, after the drilling operation instructions are generated, the currently generated drilling operation instructions are checked by the wellsite server 20. In the safety verification process, the wellsite server 20 is further configured to detect whether the execution of the current drilling operation instruction may cause the drilling operation abnormality or risk or potential risk by using the drilling risk alarms 1-11 and/or the parameter abnormality pre-warnings 1-12. If so, the wellsite server 20 is configured to generate a prompt instruction for optimizing and adjusting the current drilling operation, and push the instruction to each terminal 30 to prompt the user that the instruction needs to be optimized and adjusted; if not, the current drilling operation instruction passes the safety verification, at which point the wellsite server 20 is operable to transmit the safety verified drilling operation instruction to the rig control system via the data bus control module 10.
Specifically, in the first type of system mode, the wellsite server 20 needs to check the currently transmitted drilling operation instructions before transmitting the drilling operation instructions generated based on the analysis model decision to the drilling rig through the data bus control module, so that the drilling rig performs joint automatic control on each drilling rig equipment and/or tool according to the currently checked drilling operation instructions. In the second system mode, when the wellsite server 20 pushes the comprehensive decision result generated based on the analysis model decision to each terminal 30 and the drilling operation instruction is inputted by the terminal 30, it is necessary to check the currently inputted drilling operation instruction and display the checked drilling operation instruction on each terminal 30, so that the terminal personnel related to the current drilling operation operate the corresponding conventional drilling machine according to the checked drilling operation instruction.
Therefore, the embodiment of the invention aims to solve the problems that the existing drilling site drilling machine is old in model, frequent in personnel loss/replacement, poor in well site informationized digital level and insufficient in block adjacent well data sharing, so that the drilling site is continuously appeared: the on-site personnel can not master the situation of drilling comprehensively, mainly rely on manual experience to carry out drilling operation, the optimization effect of drilling process parameters is poor, the drilling efficiency is seriously differentiated, and the risk coping disposal capacity is weak. Meanwhile, well drilling automation and intellectualization are necessary trends of well drilling engineering development, and in future automation and intellectualization well drilling operation, a system is required to actively identify/predict/handle well drilling complex conditions and optimize well drilling operation parameters so as to realize safe and efficient well drilling.
In order to solve the current drilling site problem and meet the future automatic intelligent drilling requirements, the invention provides a driller intelligent auxiliary system for a drilling well site, which can be independently deployed in an old drilling site and can be used by embedding a drilling system in an automatic intelligent drilling machine.
When the old well drilling site is used, the informatization digitization of the well drilling site is improved through the functions of voice communication, instruction issuing, voice assistant, data input and the like of the system, the well drilling data are collected and monitored in real time, the overrun/violation operation of the well drilling driller is warned and corresponding operation rules are prompted, the built-in recognition/prediction model of abnormal and complex risks of the well drilling parameters is utilized to send alarm prompts of abnormal and complex risks of the well drilling parameters to well site drilling engineers, supervision driller, the well drilling driller, the built-in parameter optimization model is utilized to dig and analyze adjacent well data, the well drilling parameter optimization and complex situation handling suggestions are pushed to the well site drilling engineers, supervision driller, and the well drilling driller, the well drilling operation is enabled to be reasonable, and the well drilling operation is safe and efficient.
When the automatic intelligent drilling machine is used in a well site, the PLC control system of the automatic drilling machine with different data standards can be flexibly docked through the data bus control module of the system, so that the intelligent control brain of the automatic intelligent drilling machine is formed. The system now provides two modes of operation: one is an intelligent mode of operation and the other is a passive supervision mode. In an intelligent operation mode, the system takes a built-in drilling procedure and the operation performance range of drilling machine equipment as a limiting domain, analyzes the state of the well and predicts the change trend through real-time calculation, excavates mass data of a historical well to form an optimized drilling operation instruction, and sends the optimized drilling operation instruction to a PLC control system of an automatic intelligent drilling machine through a data bus control module of the system, so that the control equipment automatically completes various operation operations, optimizes drilling operation parameters, avoids potential risks, controls and processes sudden complex situations, and finally completes safe and efficient drilling operation. In a passive supervision mode, all optimized drilling operation instructions of the system are sent to an automatic intelligent drilling machine for execution after confirmation of drillers/engineers/supervision personnel, the drillers/engineers/supervision personnel/rear experts and the like can adjust/modify the operation instructions according to requirements, at the moment, the system becomes a portable and flexible semi-automatic control platform, drilling operation parameter optimization is realized under personnel supervision control, potential risks are avoided, sudden complex situations are controlled and processed, and finally safe and efficient drilling operation is completed. In the intelligent operation mode, the on-site monitoring personnel can overrun the intelligent operation mode of the cut-off system at any time to switch into the passive supervision mode.
