Description
Technical Field
The invention relates to liquid level monitoring equipment for petroleum and natural gas drilling, in particular to a non-contact ultrasonic liquid level monitoring system for petroleum underground.
Background
In oil and gas exploration and exploitation drilling, drilling mud is used for cooling a drill bit, implementing jet drilling and taking rock cut by the drill bit at the bottom of the well from the bottom of the well to the ground, and in addition, the density of the drilling mud can be adjusted to balance the mud liquid column of the annulus of the well with the pressure in the well, so that possible blowout accidents can be prevented by the balance. During the tripping process, when the drilling tool is lifted, the liquid level of the shaft is lowered, the lowering height of the liquid level is proportional to the number (length) of the tripping drill rods, and the volume of the drilling mud to be supplemented is also equivalent to the volume of the tripping drill rods, and the drilling mud is injected into the shaft through the mud injection device.
The conventional drilling mud filling device comprises a main controller, a mud tank with a stirrer, a liquid level monitor of the mud tank, a filling mechanism comprising a mud pump, a motor, an electric cabinet and a flow sensor, and an overflow return mechanism. The method for pouring is that the number of drill rods is calculated manually during the process of starting the drill, then the drill rods are input into a host machine for processing, a pouring instruction and the volume of mud to be poured into are sent to a pouring mechanism, the pouring instruction and the volume of mud to be poured into are executed and metered through a mud pump and a flow sensor arranged at the pump port, and meanwhile, information is fed back to the host machine to control the pouring amount of the drill rods.
Normally, the slurry flowing out of the slurry pond and the slurry flowing in are balanced. If an imbalance occurs, this will mean that a blow out or lost circulation will occur. When the liquid level of the slurry in the shaft is reduced, the slurry is accurately poured in time, so that the depth change of the underground drilling liquid level is necessary to be monitored in real time.
In most cases, the liquid level monitoring under the petroleum well is carried out by judging and identifying the liquid level according to manual experience, and the liquid level cannot be monitored in real time, so that the method is neither scientific nor exact.
The liquid level of the mud pit is measured, a float type liquid level detector and a scale with scales are generally adopted in the prior art, a driller is required to manually observe, record and compare, and then whether overflow or lost circulation occurs is judged. Thus, under normal conditions, the amount of mud pumped downhole from the mud tank should be substantially equal to the amount of mud returned downhole, but when lost circulation is encountered, the mud returned downhole is lost little or completely, and the mud level in the mud tank is rapidly lowered; or when the well kick is generated due to the sudden high pressure in the well, the upward pressure in the well pushes the slurry in the well annulus to kick upwards and enter the slurry tank, and the slurry level in the slurry tank can rise rapidly; when the two conditions occur, if the plugging of the grouting slurry or the implementation of well killing by the weighting slurry cannot be found and adopted in time, serious accidents are caused. In order to know the height of the liquid level in the mud tank in time, the basic method at present is to arrange personnel to detect the liquid level in the mud tank at any time when the liquid level reaches a preset level, a liquid level display is arranged on the mud tank, the other end of the display is connected with a floater through a soft rope, when the liquid level is at a set height, the floater is just floated, the reading on the display is at the set position, and when the liquid level is lowered or exceeds the set height, the display is pulled by the floater to downwards or upwards display dangerous liquid level; and the liquid level is tested by adopting sound waves or light, and an alarm is given when the upper limit and the lower limit of the liquid level are exceeded. The problems of these devices are that the former is connected by a soft rope, so that the measured liquid level is inaccurate and false alarm sometimes occurs; the latter, although using modern technology, all devices are electronic products which are easily damaged when used in the harsh environment of the drilling site, especially when the mud tank is cleaned, the electronic products are inevitably damaged, and the maintenance cost is also very expensive, and the maintenance must be completed by a professional technician.
In addition, the slurry tank has large volume, and after the well kick or the well leakage occurs, the liquid level of the slurry tank changes slowly, so that the well kick and the well leakage accident can not be monitored sensitively. Thus, a system for rapid, sensitive monitoring of mud is needed.
For the slurry liquid level in a shaft, no mature and reliable technology is used for accurately and real-time monitoring at present, the underground liquid level detection cannot be directly carried out by utilizing the ultrasonic principle, and non-contact application cannot be realized. Liquid media have also been studied abroad using ultrasound. However, even short-range transmission of ultrasonic signals is very difficult due to the scattering and absorption properties of drilling fluids (muds), especially oil-based muds, for ultrasonic waves.

[ detailed description ] of the invention
The invention is further described below with reference to the drawings and examples.

Fig. 2 is a cross-sectional view of fig. 1 (from top to bottom, an ultrasonic wave transmitting sensor groove 107, a short-distance ultrasonic wave conduction path abnormal groove 108, and an ultrasonic wave receiving sensor groove 109 in this order).
Because of the sharp attenuation characteristic of high-frequency ultrasonic waves in a gaseous medium, if the abnormal slot interface is gaseous, the ultrasonic wave receiving sensor does not receive any acoustic wave signals. If the special-shaped groove is filled with liquid medium, the ultrasonic signal can be transmitted for a short distance and is received by the ultrasonic receiving sensor, wherein the liquid medium is oil-based mud, water-based mud and high-density high-viscosity mud. The received signal is transmitted back to the ultrasonic transmitting and receiving integrated circuit through the electric wire, the received signal is transmitted to the ground through the signal wire of the steel pipe cable after the gain amplification processing of the integrated circuit, and the received signal can be obtained through the data processing or the oscilloscope on the ground. By comparing the differences of the acquired signals, the ground can judge whether the depth of the monitoring position is the slurry liquid level or the air interface. By adopting the special design, the ultrasonic sensor does not directly contact with the monitored medium, the ultrasonic transmission distance is greatly shortened, the structure is completely not influenced by water-based mud, oil-based mud and gas medium, and the liquid level of the monitoring point can be monitored. The device solves the problems that the oil-based mud can not transmit ultrasonic signals for a long distance and skillfully avoids the situation that when a drill collar is arranged in a casing, the ultrasonic waves are easy to be interfered by the drill collar to change the transmission and receiving directions.

In connection with the above construction, we will describe in detail the installation process and the working process of the present invention.
1. The upper end of the ultrasonic liquid level detector is connected with the inner sleeve, the lower end of the ultrasonic liquid level detector is connected with the coupling, and then the coupling is connected with the next inner sleeve.
2. Connecting the customized steel pipe cable with an upper joint of a branching and converging joint of an ultrasonic liquid level detector, penetrating the upper joint by using a pipe penetrating nut, a front clamping core and a rear clamping core, sealing and fastening the pipe penetrating nut; and the power signal cables are respectively connected, and the customized cable hoops and the cable protectors are connected on the inner sleeves of each section.
3. The inner casing is followed down the well, at which time the ultrasonic level monitor 1 is lowered to the desired monitoring point 1 (depth position A1), and the ultrasonic level monitor device 2 is lowered to the desired monitoring point 2 (depth position A2).
4. And the cable interfaces of the shunt and confluence connectors are respectively connected with a ground power supply system and a data acquisition machine processing and monitoring system, so that the whole set of system is connected in place.
5. Normally, in normal mud circulation, the liquid level is maintained at a level balance at depth position A1, i.e., both A1 and A2 are in the liquid medium. At this time, the special-shaped grooves on the inner walls of the integrated supporting sleeve seats of the two ultrasonic liquid level detectors are filled with flowing liquid medium, the ultrasonic liquid level detectors work normally, ultrasonic generation and pulse signal receiving are displayed, at this time, the voltage pulse waveform of each detection position point (depth position A1 and depth position A2) can be observed on the ground approximately.
6. In case of fluctuation of the slurry level, it is assumed that the liquid level drops from the A1 position to a certain depth a', where the output waveform at the A2 position is not affected at all, and the medium interface at the A1 position becomes air, where no operation is performed. When the mud liquid level drops below A2, the ultrasonic emission sensors in the ultrasonic liquid level meters at A1 and A2 pass through a steel wall with the thickness of 12mm, pass through an air medium with the width of a special-shaped groove with the thickness of 25mm, pass through the steel wall with the thickness of 12mm, and due to the divergent effect of the air medium, the ultrasonic receiving sensor arranged at the other side cannot receive the transmission signal. Therefore, the display waveforms in the A1 channel and the A2 channel on the ground are changed, and substantially no voltage pulse signal is observed. At this time, the alarm device is started to inform the ground to perform corresponding operation, mud is injected, the mud liquid level rises to a depth position A1 to reach a safe liquid level, an ultrasonic emission sensor in the ultrasonic liquid level instrument at the A1 position passes through a steel wall with the width of 12mm, mud media with the width of 25mm passes through a special-shaped groove, and the mud media passes through the steel wall with the thickness of 12mm, and due to the ultrasonic signal transmission effect of the mud media, an ultrasonic receiving sensor arranged at the other side receives a transmission signal of the mud media, and at this time, a pulse signal of a ground A1 channel is observed to return to the original approximate level.
7. When the slurry level is greatly unbalanced, for example, the liquid level is quickly reduced due to the large liquid level change in the inner sleeve after the drilling, and when the depth position A2 is set, the air medium is filled in the depth positions of the two monitoring points A1 and A2, the pulse signal of the channel A2 also quickly disappears (the principle is consistent with the 6 th item), the channels A1 and A2 simultaneously give an alarm, and the slurry filling pump is started to fill the slurry in a dangerous state. In the pouring stage, if the pouring time is too long and exceeds the theoretical time of filling the sections A1 to A2, the lost circulation is indicated, and an alarm is needed.
The invention can grasp the change condition of the liquid level in the sleeve in real time by continuously observing the ultrasonic wave transmitting and receiving signals in real time, and can understand whether the liquid level is in a safe state or an alarm state, and ground staff can grasp the depth position of the liquid level in the pit in time, so that different countermeasures can be taken.
In the technical scheme of the invention, the medium to be judged is non-contact, namely, the medium sampling is not required to be carried out by destroying the self structure of the inner sleeve, and any additional processing and changing of the inner sleeve are not required, so that the liquid level condition of the relevant monitoring point position (well depth) can be monitored in real time through a ground computer data processing system and oscillography software; in addition, the invention combines the ultrasonic liquid level monitoring principle of petroleum drilling, can also generally judge the condition of the liquid medium under the monitoring depth, can distinguish water-based mud and oil-based mud, and generally knows the specific gravity and viscosity.
The foregoing description is only of the preferred embodiments of the invention, and the above-described embodiments are not intended to limit the invention. Various changes and modifications may be made within the scope of the technical idea of the present invention, and any person skilled in the art may make any modification, modification or equivalent substitution according to the above description, which falls within the scope of the present invention.
