Definitions
- the present invention refers to a device to optimize the yield condition of oil wells and more precisely a device for the efficient control of oil extraction from oil wells.
- This innovation is based firstly on the design of new sensors and secondly on the use of computer assisted data transmission.
- sensors operated by robotics were created at a reasonable cost. That is to say, together with their low cost, their comparatively small size, in case there existed some other instrument which could be used likewise at present, in a natural manner, the value added to these is that they do not require human assistance since this technology makes them operate automatically.
- These sensors increase the amount of measurement parameters significantly, since many of the kind lack adequate measurement instruments.
- the essential object of this invention is the device which optimizes the yield of oil wells, the novelty of which consists of a piston stroke sensor capable of measuring pump piston (plunger) parameters, a dynamometer that indicates the performance and power used by the pump, a flow measuring sensor, a sensor to control the performance parameters of the engine, a degree of acidity of output flow sensor, a degree of viscosity sensor, a salinity control device of the extracted oil, a pressure and level of fluid between columns sensor and a gas detector, all of which are connected to a well control device which processes the received information and which is connected to a monitoring base.
- the said piston stroke sensor includes a data emitting device on the number of piston strokes in fractions of 1/20 in a minute.
- the pH or acidity degree sensor includes a circuit that verifies the acidity degree together with the temperature at the time of the measurement.
- the flowmeter sensor contains an element which produces a magnetic signal and not a mechanic one.
- Figure 1 is a diagram (in a block) of the designed device; and figure 2 (comprising partial figures 2a-2b) is a diagram of a section of the circuit of the device.
- the instrument is made up of basically a series of sensors connected to a processor assembly B in the data sending mode to the mentioned above and a couple of well monitoring elements connected to the outlet of such processing device.
- the processor B assembly is connected to a radio-connected monitoring base D, where all the operational data of the oil field are stored in a PC.
- Piston stroke sensor 1 provides the information of the number of piston strokes in fractions of 1/20 in a minute, thus reporting stroke length and time.
- the sensor of dynamometer 2 emits data on pump performance and power used by it.
- the flowmeter sensor 3 emits a magnetic signal, not a mechanic one, which enables with the least effort, not affecting in this way, the median flow level.
- the information is transmitted to monitoring base D every hour, and can be synchronized with all the wells of the oil field. In this way any operation that could be made and which affects the area could be observed, mainly those related to injection wells in areas of secondary recovery.
- the engine power control sensor 4 provides data that are transmitted to the base and is formed by the following parameters: voltage, current, cosine ⁇ . This sensor has an alarm system, and in the event that the critical programmed points were surpassed, enables monitoring base D to take the necessary steps before attending the well area to see to the problem and to learn that the well stopped at the time this happened.
- the multiple sensing assembly 5 includes:
- the measurement is done automatically with oil samples previously separated from the gas and the water which it could contain at the time of the extraction from the well.
- the obtained data are sent together with a report of the temperature, at the time of the measurement, with the aim of converting it into different scales used in oxidation voltage.
- Sensor 6 also provides information of the oxidation potential, having in this way a means for the control of the production pipe.
- the level of fluid between columns is done automatically as well, indicating such in m or indicating the distance between couplings or both at the same time.
- Figure 2 shows a graph of a section of the circuit to which the temperature sensors are attached (connector A), the self-potential sensor (connector B) shows the existing polarity in the production pipe to determine the oxidation voltage, the pressure sensor (connector C) verifies it every 30 minutes to evaluate its development, the pH sensor (connector D) and a choke transformer to check salinity (not shown), whose secondary is in contact with the fluid, connected to an LH2101 oscilator, all these inputs connected to the sensors through their corresponding amplification stages are connected to a conversion A/D CI-7 stage the outputs of which send data to the EEPROM CI-20 memory whose directions are controlled by the binary counter CI-19 in such a manner that a sequence of the measurements derived from the sensors is established for the purpose of sending the digital data to the monitoring board in the processor B assembly (fig. 1).
- the processor B assembly also includes a power source, a receptor, a transmitter and outlets to the well controls.
- the control board in the processor B assembly checks the value of the received data and if such surpasses the maximum pre-established critical levels it activates the well controls which consist a deviation valve 11 and a cutoff engine device 12.
