[0002] Well logging refers to the process of measuring and recording the formation, wellbore and its surrounding environment through various technical means during or after drilling to obtain geological and engineering data. The well logging hydraulic system provides power and control in this process to ensure the normal operation of the well logging equipment and the accuracy of data acquisition.

[0003] Existing logging hydraulic systems mostly adopt closed hydraulic systems and are generally used for well depths of 7,000m. For logging depths exceeding 10,000m, the capacity and safety of the hydraulic system are insufficient. When performing logging operations, it is necessary to judge the working status of the hydraulic system based on the pressure gauge values ​​and panel display values ​​on the control panel, and then operate and control the oil pump control valve, system pressure regulating valve and emergency on / off valve. This is highly dependent on the technical level of the operator.

[0004] Based on this, this patent proposes a logging hydraulic system that replaces the original pressure gauge with a multi-dimensional pressure sensor, realizing digital control of pressure. Based on the experience data and operation methods of logging operations, an operation control program is developed to realize programmed control of the winch, reducing reliance on the operator's technical skills. Compared with traditional systems, the logging hydraulic system can collect various control data required for logging, realizing digital and programmed logging control, which greatly improves the efficiency of the logging hydraulic system.

[0039] like Figure 2 As shown in the figure, this embodiment provides a functional block diagram of a well logging hydraulic system 200.

[0040] The logging hydraulic system 200 described in this embodiment can be installed in an electronic device. Depending on the functions implemented, the logging hydraulic system 200 may include a pressure sensing component 201, a metering component 202, an intelligent controller 203, a speed control component 204, an electro-proportional system pressure regulating valve 205, and a logging hydraulic winch 206. The module described in this disclosure can also be called a unit, referring to a series of computer program segments that can be executed by an electronic device processor and perform a fixed function, stored in the memory of the electronic device.

[0041] In this embodiment, the functions of each module / unit are as follows:

[0042] The pressure sensing component 201 is used to monitor the pressure of the logging hydraulic winch 206 and obtain a pressure signal set.

[0043] In detail, the hydraulic pumps and hydraulic motors of existing hydraulic systems used for logging are mostly judged and controlled by operators based on pressure gauge readings. However, the complexity of the pressure gauge readings and the difficulty of identification increase the difficulty of logging hydraulic control. In order to achieve accurate and efficient control of the hydraulic system, it is necessary to use the pressure sensing component 201 to monitor various pressure parameters inside the logging hydraulic winch 206 in real time.

[0044] In this embodiment, the pressure sensing component 201 includes a system pressure sensor, a replenishment pressure sensor, a negative pressure sensor, and an auxiliary pump pressure sensor: the system pressure sensor monitors the pressure of the hydraulic circuit of the logging hydraulic winch 206 to obtain the system pressure signal in the pressure signal group; the replenishment pressure sensor monitors the pressure of the replenishment circuit of the logging hydraulic winch 206 to obtain the replenishment pressure signal in the pressure signal group; the negative pressure sensor monitors the negative pressure of the hydraulic circuit of the logging hydraulic winch 206 to obtain the negative pressure signal in the pressure signal group; and the auxiliary pump pressure sensor monitors the pressure of the auxiliary pump of the logging hydraulic winch 206 to obtain the auxiliary pump pressure signal in the pressure signal group.

[0045] Specifically, the system pressure sensor is installed at the hydraulic pump outlet or a key location in the hydraulic circuit to monitor and provide feedback on the main supply pressure of the system. This prevents system overpressure, protects hydraulic components and equipment, and avoids malfunctions or damage caused by excessive pressure.

[0046] In detail, the replenishing pressure sensor is installed in the hydraulic oil tank or replenishing circuit to ensure that the replenishing circuit pressure is sufficient, ensuring that the hydraulic system always has enough hydraulic oil replenishment during operation, and maintaining appropriate pressure at the pump suction end to prevent cavitation caused by excessively low pressure, thus protecting the hydraulic pump and the system to operate stably.

[0047] Specifically, the negative pressure sensor is installed at the suction end of the hydraulic pump or other key locations where negative pressure needs to be monitored. It can monitor the negative pressure on the suction side of the hydraulic pump to ensure that the negative pressure is not too high, avoid cavitation damage to the hydraulic pump, and detect leakage problems in the suction side pipeline in a timely manner by monitoring the negative pressure.

[0048] In detail, the auxiliary pump pressure sensor is installed at the outlet of the auxiliary pump or in the relevant circuit to monitor and provide feedback on the pressure status of the auxiliary functions. It can ensure that the pressure provided by the auxiliary pump meets the requirements of the system's pilot control, cooling, lubrication and other auxiliary functions, and measure the operating status of the auxiliary pump to promptly detect and alarm on auxiliary pump faults or abnormal pressure conditions.

[0049] In this embodiment of the disclosure, by using the pressure sensing component 201 to monitor the pressure of the logging hydraulic winch 206, the pressure of each component of the logging hydraulic winch 206 can be monitored, the working status of the logging hydraulic winch 206 can be grasped in real time, and a digital pressure signal group can be provided, thereby reducing the difficulty of identification and analysis for operators and improving the working efficiency of the logging hydraulic system 200.

[0050] The metering component 202 is used to monitor the motion of the logging hydraulic winch 206 and obtain a set of motion signals.

[0051] In detail, the logging environment of existing hydraulic systems for well logging is mostly determined and analyzed by the operators themselves. In order to achieve accurate and efficient control of the hydraulic system, it is necessary to use the metering component 202 to monitor various external environmental parameters when the logging hydraulic winch 206 is working in real time.

[0052] In this embodiment of the disclosure, when the metering component 202 performs the function of monitoring the motion of the logging hydraulic winch 206 to obtain a motion signal group, it is specifically used for: monitoring the operating speed of the logging hydraulic winch 206 to obtain the logging speed in the motion signal group; monitoring the logging depth of the logging hydraulic winch 206 to obtain the logging depth in the motion signal group; monitoring the winch tension of the logging hydraulic winch 206 to obtain the winch tension in the motion signal group; and generating a motion signal group based on the logging speed, the logging depth, and the winch tension.

[0053] Specifically, the rotational speed of the winch motor or drum can be measured in real time using the rotational speed sensor in the metering component 202, and the logging speed of the winch can be calculated indirectly. The rotational speed sensor can be a photoelectric rotational speed sensor or a magnetoelectric rotational speed sensor, and the rotational speed sensor can be installed on the winch drum of the logging hydraulic winch 206.

[0054] In detail, the logging depth can be monitored using a line length gauge or laser rangefinder in the metering component 202. The line length gauge monitors the logging depth by measuring the length of the winch cable released or retrieved. The line length gauge can be a mechanical line length gauge or an electronic line length gauge.

[0055] Specifically, the tension sensor in the metering component 202 can be used to monitor the tension of the winch. The tension sensor ensures safety and data accuracy during the logging process by directly measuring the tension of the winch. The tension sensor can be a load pin type tension sensor or a force gauge type tension sensor.

[0056] In this embodiment of the disclosure, by using the metering component 202 to monitor the motion of the logging hydraulic winch 206, the speed, depth and tension of the logging hydraulic winch 206 can be understood in real time, thereby avoiding logging overspeed, reducing the risk of rope breakage, effectively preventing equipment damage, and providing a digital motion signal set to facilitate further intelligent logging analysis and improve the working efficiency of the logging hydraulic system 200.

[0057] The intelligent controller 203 is used to generate control signals based on the pressure signal group and the motion signal group, and to adjust the hydraulic pressure of the logging hydraulic winch 206 based on the control signals and the electro-proportional system pressure regulating valve 205.

[0058] Specifically, existing hydraulic systems used for well logging are mostly controlled by operators based on pressure gauge readings. However, the complexity of the pressure gauge readings and the difficulty in identifying them increase the difficulty of well logging hydraulic control. The intelligent controller 203 can combine previous well logging data and well parameters to generate intelligent control signals to assist operators in well logging operations. The control signals refer to the electrical signals that control the speed control component 204 and the electro-proportional system pressure regulating valve 205.

[0059] In this embodiment of the disclosure, when the intelligent controller 203 performs the function of generating a control signal based on the pressure signal group and the motion signal group, it is specifically used to: simulate environmental pressure on the motion signal group to obtain a simulated pressure signal group; compare the deviation between the simulated pressure signal group and the pressure signal group to obtain a deviation signal value; and adjust the deviation signal value to obtain a control signal.

[0060] In detail, the intelligent controller 203 can combine previous logging data and oil well parameters, and collect pressure signal groups and motion signal groups of high-quality operators during their work. It can generate a pressure signal simulation model through deep learning models or convolutional neural networks, and use the pressure signal simulation model to simulate environmental pressure on the motion signal groups.

[0061] Specifically, the simulated pressure signal set is the optimal pressure signal set simulated in real time based on the motion signal set. The deviation signal value includes the deviation values ​​between the system pressure signal, the replenishment pressure signal, the negative pressure signal, and the auxiliary pump pressure signal and the output of the prediction model, thereby reflecting the potential problems of the existing control scheme.

[0062] Specifically, it is possible to combine previous logging data and oil well parameters, and collect pressure signal groups and control signals from high-quality operators during their work. A control signal model can be generated through deep learning models or convolutional neural networks, and the control signal model can be used to adjust and feedback according to the deviation signal value to generate a control signal.

[0063] Specifically, in ultra-deep logging operations, the hydraulic system of the logging hydraulic winch 206 needs to provide sufficient hydraulic pressure and perform precise hydraulic pressure control. For this purpose, the pressure control is achieved using the electro-proportional system pressure regulating valve 205.

[0064] In detail, the electro-proportional system pressure regulating valve 205 is used to regulate the hydraulic pressure of the hydraulic system of the logging hydraulic winch 206. The hydraulic pressure is the pressure actually applied to actuators such as hydraulic cylinders or hydraulic motors during the operation of the logging hydraulic winch 206. The hydraulic pressure can control the load-bearing and lifting force of the winch drum of the logging hydraulic winch 206.

[0065] In this embodiment of the disclosure, when the intelligent controller 203 performs the function of adjusting the hydraulic pressure of the logging hydraulic winch 206 according to the control signal and the electro-proportional system pressure regulating valve 205, it is specifically used to: adjust the valve port area and valve core position of the electro-proportional system pressure regulating valve 205 according to the control signal to change the hydraulic channel area of ​​the logging hydraulic winch 206, thereby adjusting the hydraulic pressure of the logging hydraulic winch 206.

[0066] In detail, the electromagnet of the electro-proportional system pressure regulating valve 205 can be controlled by the control signal, thereby adjusting the valve port area of ​​the electro-proportional system pressure regulating valve 205. The valve port area adjustment refers to the valve port area of ​​the electro-proportional system regulating valve.

[0067] Specifically, the control signal can be used to generate magnetic force, which can be used to push the valve core of the electro-proportional system pressure regulating valve 205 to move. The valve core position refers to the position of the valve core in the electro-proportional system pressure regulating valve 205.

[0068] Specifically, the hydraulic regulating valve port and the hydraulic regulating valve core can regulate the flow rate and pressure of the hydraulic oil in the logging hydraulic winch 206, thereby changing the back pressure and flow rate of the logging hydraulic winch 206, and thus regulating the hydraulic pressure of the logging hydraulic winch 206.

[0069] In this embodiment of the disclosure, by controlling the hydraulic pressure of the logging hydraulic winch 206 according to the electro-proportional system pressure regulating valve 205 and the control signal, the hydraulic pressure of the hydraulic system can be precisely changed, thereby improving the lifting capacity of the winch during logging operations.

[0070] In this embodiment of the disclosure, by using the intelligent controller 203 to generate control signals based on the pressure signal group and the motion signal group, the optimal control scheme can be analyzed through intelligent theoretical mathematical models under different pressure measurement environments and pressure measurement machine states, thereby protecting well logging safety and improving well logging efficiency.

[0071] The speed control component 204 is used to control the rotational speed and direction of the logging hydraulic winch 206 according to the control signal.

[0072] Specifically, logging equipment with a depth exceeding 10,000 meters has a large load and higher requirements for equipment safety. It requires more precise control of the rotation speed and direction of the logging hydraulic winch 206. Therefore, a more stable and safer speed control component 204 needs to be selected for speed control.

[0073] In this embodiment, the speed control component 204 includes an oil pump motor control component, an electrically controlled bidirectional plunger variable oil pump, and an electrically controlled variable motor. The oil pump motor control component is used to acquire the control signal from the intelligent controller 203 and send the control signal to the electrically controlled bidirectional plunger variable oil pump and the electrically controlled variable motor, respectively. The control signal is used to drive the electrically controlled bidirectional plunger variable oil pump to output high-pressure oil. The high-pressure oil is used to drive the electrically controlled variable motor to rotate. The electrically controlled variable motor is used to drive the winch drum of the logging hydraulic winch 206 to rotate and control the speed and direction of the winch drum according to the control signal.

[0074] In detail, the oil pump motor control component is used to control the displacement of the electronically controlled bidirectional plunger variable oil pump and the electronically controlled variable motor according to the control signal. The electronically controlled bidirectional plunger variable oil pump can output high-pressure oil with different displacements.

[0075] Specifically, the logging hydraulic winch 206 includes a reducer and a winch drum. The electrically controlled variable motor is used to drive the reducer to rotate, the reducer is used to drive the winch drum to rotate, and the winch drum is used to lift and lower the downhole instruments through the winch rope, thereby realizing logging.

[0076] In detail, changing the displacement of the electrically controlled bidirectional plunger variable oil pump and the electrically controlled variable motor can change the rotational speed of the reducer, thereby changing the lifting and lowering speeds during logging.

[0077] In detail, the control signal is an electrical signal used to control the high-pressure oil displacement of the electronically controlled bidirectional piston variable oil pump and the displacement, speed, direction, and torque of the electronically controlled variable motor. The control signal can be transmitted via a signal line to control the displacement of the electronically controlled bidirectional piston variable oil pump. The high-pressure oil refers to the high-pressure hydraulic oil output by the electronically controlled bidirectional piston variable oil pump.

[0078] Specifically, the high-pressure oil can provide hydraulic energy to the electronically controlled variable motor, and the oil pump motor control component can control the displacement, speed, direction, torque and other parameters of the electronically controlled variable motor through the electrical signals in the control signal.

[0079] In detail, the output of the electronically controlled variable motor generates a set rotational force, which in turn drives the reducer to rotate. The rotational drive of the winch drum of the logging hydraulic winch 206 means that the reducer will drive the reducer to rotate after the rotational drive.

[0080] In this embodiment of the disclosure, by using the speed control component 204 to control the rotational speed and direction of the logging hydraulic winch 206 according to the control signal, a high-performance hydraulic oil pump and hydraulic motor can be used for logging drive, thereby improving the stability of the logging hydraulic system 200 and realizing digital and information-based logging control, thus improving the accuracy of the logging hydraulic system 200.

[0081] The well logging hydraulic system 200 provided in this disclosure monitors the pressure of the well logging hydraulic winch 206 by using the pressure sensing component 201. This enables the monitoring of the pressure of each component of the well logging hydraulic winch 206, real-time monitoring of the working status of the well logging hydraulic winch 206, and provides a digital pressure signal group, thereby reducing the difficulty of identification and analysis for operators and improving the working efficiency of the well logging hydraulic system 200.

[0082] By using the metering component 202 to monitor the motion of the logging hydraulic winch 206, the speed, depth and tension of the logging hydraulic winch 206 can be understood in real time, thereby avoiding logging overspeed, reducing the risk of rope breakage, effectively preventing equipment damage, and providing a digital motion signal group to facilitate further intelligent logging analysis and improve the working efficiency of the logging hydraulic system 200.

[0083] By using the intelligent controller 203 to generate control signals based on the pressure signal group and the motion signal group, the optimal control scheme can be analyzed through intelligent theoretical mathematical models under different pressure measurement environments and pressure measurement machine states, thereby protecting well logging safety and improving well logging efficiency.

[0084] By using the speed control component 204 to control the rotational speed and direction of the logging hydraulic winch 206 according to the control signal, and by using the electro-proportional system pressure regulating valve 205 to control the hydraulic pressure of the logging hydraulic winch 206 according to the control signal, the hydraulic pressure of the hydraulic system can be precisely changed, thereby improving the hoisting capacity of the winch during logging operations, enhancing the stability of the logging hydraulic system 200, realizing digital and information-based logging control, and improving the accuracy of the logging hydraulic system 200.

[0093] In this embodiment of the disclosure, the metering component 302 is used to monitor the operating speed of the logging hydraulic winch 306 to obtain the logging speed in the motion signal group; the metering component 302 is used to monitor the logging depth of the logging hydraulic winch 306 to obtain the logging depth in the motion signal group; the metering component 302 is used to monitor the winch tension of the logging hydraulic winch 306 to obtain the winch tension in the motion signal group.

[0094] The safety controller 303 is used to generate control signals and warning signals based on the pressure signal group and the motion signal group, and to adjust the hydraulic pressure of the logging hydraulic winch 306 based on the control signals and the electro-proportional system pressure regulating valve 305.

[0095] Specifically, existing hydraulic systems used for well logging are mostly controlled by operators based on pressure gauge readings. However, the complexity of pressure gauge readings and the difficulty in identifying them increase the difficulty of well logging hydraulic control and may pose certain safety hazards. The safety controller 303 can combine previous well logging data and well parameters to generate intelligent control signals, ensuring the safety of well logging operations.

[0096] In this embodiment of the disclosure, when the safety controller 303 performs the function of generating control signals and warning signals based on the pressure signal group and the motion signal group, it is specifically used to: perform motion comparison analysis on the motion signal group to obtain motion deviation values; perform pressure comparison analysis on the pressure signal group to obtain pressure deviation values; perform threshold detection on the motion deviation values ​​and the pressure deviation values ​​to obtain warning information; and perform adjustment feedback based on the warning information to obtain control signals.

[0097] In detail, the safety controller 303 can combine previous logging data and oil well parameters, and collect high-quality operator motion signal data during operation to perform motion comparison analysis on the motion signal group. The motion deviation value refers to the deviation value between the logging speed, the logging depth, the winch tension and the predicted signal threshold in the motion signal group.

[0098] Specifically, the safety controller 303 can combine previous logging data and oil well parameters, and collect high-quality pressure signal data from operators during their work to perform motion comparison analysis on the pressure signal group. The pressure deviation value refers to the deviation between the system pressure signal, the replenishment pressure signal, the negative pressure signal, and the auxiliary pump pressure signal in the motion signal group and the predicted signal threshold.

[0099] Specifically, when performing threshold detection, the safety controller 303 is used to detect whether the motion deviation value and pressure deviation value exceed a preset deviation threshold. If so, it generates a warning message based on the corresponding deviation value. For example, when the motion deviation value of the rope tension exceeds the preset deviation threshold, the rope may break, and the warning message is a rope breakage warning message.

[0100] Specifically, it is possible to combine previous well logging data and oil well parameters, and collect pressure signal sets and control signals from experienced operators during their work. Then, through deep learning models or convolutional neural networks, the control signals can be obtained by adjusting and feeding back the warning information.

[0101] In this embodiment of the disclosure, by using the safety controller 303 to generate control signals based on the pressure signal group and the motion signal group, the optimal control scheme can be determined through safety threshold analysis under different pressure measurement environments and pressure measurement machine states, thereby protecting well logging safety and improving well logging safety.

[0102] In detail, the electro-proportional system pressure regulating valve 305 is used to regulate the hydraulic pressure of the hydraulic system of the logging hydraulic winch 306.

[0104] In detail, the electromagnet of the electro-proportional system pressure regulating valve 305 can be controlled by the control signal, thereby adjusting the valve port area of ​​the electro-proportional system pressure regulating valve 305. The valve port area adjustment refers to the valve port area of ​​the electro-proportional system regulating valve.

[0105] Specifically, the control signal can be used to generate a magnetic force, which can be used to push the valve core of the electro-proportional system pressure regulating valve 305 to move. The valve core position refers to the position of the valve core in the electro-proportional system pressure regulating valve 305.

[0106] Specifically, the hydraulic regulating valve port and the hydraulic regulating valve core can regulate the flow rate and pressure of the hydraulic oil in the logging hydraulic winch 306, thereby changing the back pressure and flow rate of the logging hydraulic winch 306, and thus regulating the hydraulic pressure of the logging hydraulic winch 306.

[0107] In this embodiment of the disclosure, by controlling the hydraulic pressure of the logging hydraulic winch 306 according to the electro-proportional system pressure regulating valve 305 and the control signal, the hydraulic pressure of the hydraulic system can be precisely changed, thereby improving the lifting capacity of the winch during logging operations.

[0108] The speed control component 304 is used to control the rotational speed and direction of the logging hydraulic winch 306 according to the control signal.

[0109] In this embodiment, the speed control component 304 includes an oil pump motor control component, an electrically controlled bidirectional plunger variable oil pump, and an electrically controlled variable motor.

The high-pressure oil is used to drive the electrically controlled variable motor to rotate. The electrically controlled variable motor is used to drive the winch drum of the logging hydraulic winch 306 to rotate and control the speed and direction of the winch drum according to the control signal.

[0110] Example 3

[0111] Based on the above embodiments, this embodiment provides an application example, such as... Figure 4 As shown, this disclosure also proposes a well logging hydraulic method, comprising the following steps:

[0112] S1. Use pressure sensing components to collect pressure signals from the logging hydraulic winch to obtain a pressure signal set.

[0113] In detail, in order to achieve efficient acquisition of system pressure data during the operation of the well logging hydraulic winch, thereby realizing precise control and intelligent early warning of the well logging hydraulic winch, pressure signal acquisition is required. The pressure sensing components include a system pressure sensor, a replenishment pressure sensor, a negative pressure sensor, and an auxiliary pump pressure sensor. The pressure signal group includes system pressure signal, replenishment pressure signal, negative pressure signal, and auxiliary pump pressure signal.

[0114] In this embodiment of the invention, the step of acquiring pressure signals from the logging hydraulic winch using pressure sensing components to obtain a pressure signal group includes: monitoring the pressure of the hydraulic circuit of the logging hydraulic winch using pressure sensing components to obtain a system pressure signal; monitoring the pressure of the oil replenishment circuit of the logging hydraulic winch using pressure sensing components to obtain an oil replenishment pressure signal; monitoring the negative pressure of the hydraulic circuit of the logging hydraulic winch using pressure sensing components to obtain a negative pressure signal; monitoring the pressure of the auxiliary pump of the logging hydraulic winch using pressure sensing components to obtain an auxiliary pump pressure signal; and merging the system pressure signal, the oil replenishment pressure signal, the negative pressure signal, and the auxiliary pump pressure signal into a pressure signal group.

[0115] In detail, the system pressure signal can be monitored using a system pressure sensor, the replenishment pressure signal can be monitored using a replenishment pressure sensor, the negative pressure signal can be monitored using a negative pressure sensor, and the auxiliary pump pressure signal can be monitored using an auxiliary pump pressure sensor.

[0116] Specifically, the system pressure sensor is installed at the hydraulic pump outlet or a key location in the hydraulic circuit to monitor and provide feedback on the main supply pressure of the system. This prevents system overpressure, protects hydraulic components and equipment, and avoids malfunctions or damage caused by excessive pressure.

[0117] In detail, the replenishing pressure sensor is installed in the hydraulic oil tank or replenishing circuit to ensure that the replenishing circuit pressure is sufficient, ensuring that the hydraulic system always has enough hydraulic oil replenishment during operation, and maintaining appropriate pressure at the pump suction end to prevent cavitation caused by excessively low pressure, thus protecting the hydraulic pump and the system to operate stably.

[0118] Specifically, the negative pressure sensor is installed at the suction end of the hydraulic pump or other key locations where negative pressure needs to be monitored. It can monitor the negative pressure on the suction side of the hydraulic pump to ensure that the negative pressure is not too high, avoid cavitation damage to the hydraulic pump, and detect leakage problems in the suction side pipeline in a timely manner by monitoring the negative pressure.

[0119] In detail, the auxiliary pump pressure sensor is installed at the outlet of the auxiliary pump or in the relevant circuit to monitor and provide feedback on the pressure status of the auxiliary functions. It can ensure that the pressure provided by the auxiliary pump meets the requirements of the system's pilot control, cooling, lubrication and other auxiliary functions, and measure the operating status of the auxiliary pump to promptly detect and alarm on auxiliary pump faults or abnormal pressure conditions.

[0120] S2. Use the metering components to collect motion signals from the logging hydraulic winch to obtain a motion signal set.

[0121] Specifically, in order to monitor the working status of the logging hydraulic winch in real time, it is necessary to collect motion signals of the working environment of the logging hydraulic winch and the key winch drum. The motion signal set includes logging speed, logging depth and winch tension.

[0122] For details, refer to Figure 5 As shown, the method of using a metering component to acquire motion signals from the logging hydraulic winch to obtain a motion signal set includes:

[0125] S53. Use the metering component to monitor the winch tension of the logging hydraulic winch and obtain the winch tension.

[0126] S54. Combine the logging speed, the logging depth, and the winch tension into a motion signal group.

[0127] Specifically, the rotational speed of the winch motor or drum can be measured in real time using the rotational speed sensor in the metering component, and the logging speed of the winch can be calculated indirectly. The rotational speed sensor can be a photoelectric rotational speed sensor or a magnetoelectric rotational speed sensor, and the rotational speed sensor can be installed on the winch drum of the logging hydraulic winch.

[0128] In detail, the logging depth can be monitored using a line length gauge or laser rangefinder in the metering assembly. The line length gauge monitors the logging depth by measuring the length of the winch cable released or retrieved. The line length gauge can be a mechanical line length gauge or an electronic line length gauge.

[0129] Specifically, the tension sensor in the metering component can be used to monitor the tension of the winch. The tension sensor ensures safety and data accuracy during the logging process by directly measuring the tension of the winch. The tension sensor can be a load pin type tension sensor or a force gauge type tension sensor.

[0130] S3. The intelligent controller analyzes the motion state of the logging hydraulic winch based on the pressure signal group and the motion signal group to obtain the control signal.

[0131] In this embodiment of the invention, the step of using an intelligent controller to analyze the motion state of the logging hydraulic winch based on the pressure signal group and the motion signal group to obtain a control signal includes: using the intelligent controller to simulate environmental pressure on the motion signal group to obtain a simulated pressure signal group; using the pressure signal group to compare the deviation of the simulated pressure signal group to obtain a deviation signal value; and using the deviation signal value of the intelligent controller to perform adjustment feedback to obtain a control signal.

[0132] In detail, it is possible to combine previous well logging data and oil well parameters, and collect pressure signal groups and motion signal groups from high-quality operators during their work, and generate a pressure signal simulation model through deep learning models or convolutional neural networks, and then use the pressure signal simulation model to simulate the environmental pressure of the motion signal groups.

[0133] Specifically, the simulated pressure signal set is the optimal pressure signal set simulated in real time based on the motion signal set. The deviation signal value includes the deviation values ​​between the system pressure signal, the replenishment pressure signal, the negative pressure signal, and the auxiliary pump pressure signal and the output of the prediction model, thereby reflecting the potential problems of the existing control scheme.

[0134] Specifically, it is possible to combine previous logging data and oil well parameters, and collect pressure signal groups and control signals from high-quality operators during their work. A control signal model can be generated through deep learning models or convolutional neural networks, and the control signal model can be used to adjust and feedback according to the deviation signal value to generate a control signal.

The oil pump motor control component is used to control the displacement of the electronically controlled bidirectional plunger variable oil pump and the electronically controlled variable motor according to the control signal. The electronically controlled bidirectional plunger variable oil pump can output high-pressure oil with different displacements.

[0137] Specifically, the logging hydraulic winch includes a reducer and a winch drum. The electrically controlled variable motor drives the reducer to rotate, the reducer drives the winch drum to rotate, and the winch drum drives the downhole instruments to be lifted and lowered via a winch rope, thereby realizing logging.

[0138] In detail, the oil pump motor control component is used to control the displacement of the electronically controlled bidirectional plunger variable oil pump and the electronically controlled variable motor according to the control signal. The electronically controlled bidirectional plunger variable oil pump can output high-pressure oil with different displacements.

[0139] In detail, changing the displacement of the electrically controlled bidirectional plunger variable oil pump and the electrically controlled variable motor can change the rotational speed of the reducer, thereby changing the lifting and lowering speeds during logging.

[0140] In detail, the control signal is an electrical signal used to control the high-pressure oil displacement of the electronically controlled bidirectional piston variable oil pump and the displacement, speed, direction, and torque of the electronically controlled variable motor. The control signal can be transmitted via a signal line to control the displacement of the electronically controlled bidirectional piston variable oil pump. The high-pressure oil refers to the high-pressure hydraulic oil output by the electronically controlled bidirectional piston variable oil pump.

[0141] Specifically, the high-pressure oil can provide hydraulic energy to the electronically controlled variable motor, and the oil pump motor control component can control the displacement, speed, direction, torque and other parameters of the electronically controlled variable motor through the electrical signals in the control signal.

[0142] In detail, the output of the electronically controlled variable motor generates a set rotational force, which in turn drives the reducer to rotate. The rotational drive of the winch drum of the logging hydraulic winch means that the reducer will drive the reducer to rotate after the rotational drive.

[0143] S5. The intelligent controller is used to control the hydraulic pressure of the logging hydraulic winch according to the pressure regulating valve of the electro-proportional system and the control signal.

[0144] Specifically, the step of using the intelligent controller to control the hydraulic pressure of the logging hydraulic winch according to the electro-proportional system pressure regulating valve and the control signal includes: using the intelligent controller to send the control signal to the electro-proportional pressure regulating valve; using the electro-proportional system pressure regulating valve to control the valve area of ​​the logging hydraulic winch according to the control signal; and using the electro-proportional system pressure regulating valve to control the valve core position of the logging hydraulic winch according to the control signal.

[0145] In detail, the logging hydraulic method described in this embodiment uses the same technical means as the modules in the logging hydraulic system described in Embodiments 1 and 2, and can produce the same technical effects, which will not be repeated here.

[0146] In detail, the electromagnet of the electro-proportional system pressure regulating valve can be controlled by the control signal, thereby adjusting the valve port area of ​​the electro-proportional system pressure regulating valve. The valve port area adjustment refers to the valve port area of ​​the electro-proportional system regulating valve.

[0147] Specifically, the control signal can be used to generate magnetic force, which can be used to move the valve core of the electro-proportional system pressure regulating valve. The valve core position refers to the position of the valve core in the electro-proportional system pressure regulating valve.

[0148] Specifically, the hydraulic regulating valve port and the hydraulic regulating valve core can regulate the flow rate and pressure of the hydraulic oil in the logging hydraulic winch, thereby changing the back pressure and flow rate of the logging hydraulic winch, and thus regulating the hydraulic pressure of the logging hydraulic winch.

[0149] In this embodiment of the disclosure, by using an electro-proportional system pressure regulating valve to control the hydraulic pressure of the logging hydraulic winch according to the control signal, the hydraulic pressure of the hydraulic system can be precisely changed, thereby improving the lifting capacity of the winch during logging operations.
