Description

Technical Field

[0001] This invention relates to the field of oil extraction technology, and in particular to a drum-type fully enclosed automated and environmentally friendly pumping device. Background Technology

[0002] In the process of determining the reservoir productivity, fluid properties, and pressure through the oil testing process, the pumping and drainage technology can effectively reduce the bottom hole pressure and induce fluid in the bottom layer to flow into the well. This technology is widely used in oilfields across China.

[0003] Faced with an increasingly severe safety and environmental situation, local governments, oilfields, and companies have raised higher requirements for safety and environmental protection work in oil testing. Existing pumping and drainage technologies suffer from problems such as the inability to seal the wellhead and the inability of the wellhead pumping equipment to operate continuously for 24 hours. These technologies also result in high energy consumption, large labor requirements, and issues such as poor sealing leading to carryover and wellhead contamination, which constitute a bottleneck restricting the development of oilfield production and recovery technologies.

[0004] Traditional pumping operations primarily utilize downhole and well-dredging rigs. These operations are characterized by large footprints, lengthy installation and adjustment times, and the need for personnel to remain on-site for extended periods. They also demand highly skilled operators; any misjudgment, operational errors, data misinterpretation, or delayed response can lead to dangerous situations, such as getting stuck, rope breakage, collisions with above, or falls. Frequent shift work and the need for a large number of skilled technicians are also prominent issues in recent years. Another problem is the difficulty in continuous operation during inclement weather, such as rain, thunderstorms, or dense fog, which impairs visibility.

[0005] Well dredging rigs already consume a significant amount of diesel fuel, and as the equipment ages, fuel consumption and maintenance costs are increasing. Therefore, this type of well pumping device does not meet today's green, energy-saving, and environmentally friendly requirements, and urgently needs to be replaced by a cleaner, low-energy-consumption, highly automated device that requires less labor.

[0006] In the process of oilfield exploration and development, reservoir productivity, fluid properties, and formation parameters are obtained through oil testing operations. The fluid drainage and production assessment process during oil testing is a crucial step in accurately understanding reservoir productivity and fluid properties. Currently, the most common method for fluid drainage and production assessment in non-flowing wells in oilfields is pumping operations. However, traditional pumping operations are outdated, pose high environmental pollution risks, involve high labor intensity for personnel, have high skill requirements, and have low levels of automation.

[0007] Well surveys indicate that existing pumping devices fall into two categories:

[0008] 1. A pumping and drainage device for low-pressure, low-production wells, designed and improved by technicians from an oilfield, mainly consists of a high-strength pumping unit and a wellhead blowout preventer for well pumping. This technology optimizes and improves the structure and safety of the downhole pump, but does not address wellhead environmental protection or the wellhead power unit.

[0009] 2. The energy-saving and environmentally friendly continuous fluid discharge device for well testing, designed by technicians from a certain downhole operation company, mainly consists of a surface lifting system and a downhole pumping system. This technology is not suitable for the long-stroke wire rope pumping operations, flexible pumping operations in deep well sections, and the stringent environmental protection requirements at the wellhead used in Great Wall downhole drilling.

[0010] Existing pumping equipment is mostly powered by well cleaning rigs or retrieval vehicles. It uses a wire rope and tubing pump to lift and discharge well fluid from the tubing for oil testing and production assessment. All of these operations are conducted manually in shifts. Although the pumping process is simple, it relies heavily on the operator's skill level. Continuous pumping requires a large number of skilled workers working in shifts, resulting in high labor intensity. This necessitates high levels of personnel competence and a strong sense of responsibility.

[0011] Safety is always the top priority in production. Accidents such as jamming inside the wellbore are common. Fatigue and misjudgment caused by prolonged repetitive work by operators can lead to accidents like overshooting or crashing. Overheating of equipment during extended operation and mechanical failures can also cause runaway, resulting in rope breakage and subsequent collisions. Severe weather is another contributing factor. Extreme cold or heat causing discomfort to personnel during prolonged work, as well as rain, snow, and fog, can all lead to accidents during continuous pumping operations.

[0012] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a drum-type fully enclosed automated environmentally friendly pumping device. Summary of the Invention

[0013] The purpose of this invention is to provide a drum-type fully enclosed automated environmentally friendly pumping device.

[0033] Furthermore, the traction rope passes over the ground pulley at the bottom of the rope rack, passes over the top pulley at the top of the rope rack, and extends along the axis of the wellhead into the wellhead drainage pipe.

[0034] The wellhead remote digital tension meter is used to detect the tension change of the pumping rope in real time. It uses strain gauge sensors to sense the tensile deformation of the pumping rope and converts it into an electrical signal to be transmitted to the control system.

[0035] A pressure transmitter is installed on the wellhead drainage pipeline. The pressure transmitter converts the wellhead pressure into a standard electrical signal and transmits it to the control system through the PLC analog input module.

[0036] A temperature sensor is installed on the wellhead drainage pipeline. The temperature sensor converts the wellhead temperature signal into an electrical signal and transmits it to the control system through the PLC analog input module.

[0037] Furthermore, the hydraulic system integrates multiple hydraulic pressure sensors to monitor the pressure changes of the hydraulic system of the pumping device, convert the hydraulic system pressure into an electrical signal, and transmit it to the control system through the PLC analog input module.

[0038] The hydraulic tank integrates a temperature sensor, which monitors the temperature changes of the hydraulic system of the pumping device and converts the temperature of the hydraulic system into an electrical signal, which is then transmitted to the control system via the PLC analog input module.

[0050] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0051] See Figures 1 to 2 As shown;

[0052] This embodiment discloses a drum-type fully enclosed automated environmentally friendly pumping device, which includes:

[0053] Panoramic control room 2, which is equipped with a control system;

[0054] Hydraulic system 5;

[0055] The hydraulic system 5 is connected to the hydraulic tank 6 via hydraulic pipes to receive hydraulic oil.

[0056] The hydraulic roller mechanism 7 is connected to the hydraulic system 5 via a hydraulic pipe. The hydraulic roller 702 of the hydraulic roller mechanism 7 is wound with a suction rope 704, which extends toward the downstream end of the process.

[0057] The device also includes a wellhead three-level protection environmentally friendly blowout preventer 804 located downstream of the hydraulic roller mechanism 7. The wellhead three-level protection environmentally friendly blowout preventer 804 is installed at the wellhead, and a drain pipe 806 is located below the wellhead.

[0058] A rope rack 801 is installed at the wellhead location;

[0059] The rope rack 801 integrates a wellhead remote transmission digital tension meter 804.

[0060] Specifically, this embodiment discloses a drum-type fully enclosed automated environmentally friendly pumping device, forming a complete and practical fully automated environmentally friendly pumping technology, solving the environmental problem of spillage and splashing during pumping operations. It addresses the issues of high personnel requirements and reduced operational skill difficulty during operation. Using the device of this embodiment, only two operators per shift are needed for automatic control, resulting in low workload, low risk, and low dependence on technical personnel. It also solves the safety issues during operation. The PLC controller of the control system collects and records various parameters through the data acquisition module, including tension parameters, pumping pressure monitoring, power monitoring, pumping depth, stroke count, displacement data, resistance index, wind speed, and horizontal parameters. Furthermore, it can perform safety analysis and prediction to prevent safety problems during construction.

[0061] Preferably, in this embodiment, the panoramic operating room 2, hydraulic system 5, hydraulic oil tank 6, and hydraulic roller mechanism 7 are all integrated on the ground via skid-mounted mechanism 1;

[0062] Skid-mounted mechanism 1 includes:

[0063] The load-bearing skid 101 has a pipeline laying frame for laying hydraulic pipes on its side.

[0064] The load-bearing skid 101 is positioned to mate with the panoramic operating room 2, and a shock-absorbing structure is installed at the bottom of the panoramic operating room 2.

[0065] In this embodiment, the panoramic operating room 2 has an explosion-proof control cabinet 3 and a radiator 4 integrated on the rear side; the hydraulic system 5 has an explosion-proof motor 501, a hydraulic pump station 503 and a hydraulic motor 502 integrated inside.

[0066] First, this embodiment further introduces the explosion-proof electric drive system, which mainly consists of an explosion-proof motor 501, a soft starter, and an explosion-proof control cabinet 3. The explosion-proof motor 501 features high efficiency, low noise, and excellent explosion-proof performance, enabling stable operation in harsh environments. The soft starter is used to achieve smooth motor starting, reducing current surges and mechanical stress during startup and extending the motor's service life. The explosion-proof control cabinet 3 provides centralized control of the motor and other circuit components, possessing explosion-proof, dustproof, and waterproof functions to ensure the safety and reliability of the control system.

[0067] The explosion-proof electric drive module in this embodiment is also equipped with a circuit operating parameter sensor: to monitor the circuit's operating parameters in real time, such as current, voltage, and temperature, providing real-time data support for the control system's decision-making. It also includes a circuit operating parameter receiver: to receive the data collected by the sensor, preprocess it, and transmit the processed data to the subsequent analysis module. Finally, a circuit parameter collection and analysis module: to perform in-depth analysis of the data transmitted by the receiver, determine the circuit's operating state, and adjust the control strategy based on the analysis results to ensure the safe and stable operation of the circuit.

[0068] The control logic of the explosion-proof electric drive system in this embodiment mainly includes the following steps:

[0069] 1. Initialization: Before system startup, each component performs a self-check to ensure it is in normal working condition. Control parameters are initialized to adapt to different working environments and requirements.

[0070] 2. Data Acquisition and Processing: Operating parameters of the circuit, such as current, voltage, and temperature, are acquired in real time via circuit operating parameter sensors. The acquired data undergoes preprocessing by the circuit operating parameter receiver, including filtering, noise reduction, and data format conversion, to ensure the accuracy and validity of the data.

[0071] 3. Data Analysis and Judgment: The circuit initial signal collection and analysis module performs in-depth analysis of the preprocessed data and determines whether the circuit is in normal working condition by comparing it with preset safety thresholds. If abnormal data is detected, such as excessive current or excessive temperature, an alarm mechanism is immediately triggered, and corresponding fault handling is performed.

[0072] 4. Control Strategy Adjustment: Based on data analysis results, the control strategy is dynamically adjusted. For example, during motor startup, a soft starter is used to achieve a smooth start and reduce current surges; when the circuit load is too high, the motor speed or power output is adjusted to reduce the circuit's workload and ensure safe and stable circuit operation.

[0073] 5. Fault Handling and Recording: When a fault is detected, the control system will immediately take corresponding measures, such as cutting off the power supply and activating backup equipment, to prevent the fault from escalating and causing more serious consequences. The system will automatically record information such as the time, type, and cause of the fault, facilitating subsequent fault diagnosis and maintenance.

[0074] Preferably, the hydraulic roller mechanism 7 in this embodiment includes a hydraulically driven roller support 701 integrated in the bearing skid 101; and a hydraulically driven roller 702 integrated in the hydraulically driven roller support 701 and rotatably connected to the hydraulically driven roller support 701.

[0075] The front side of the hydraulically driven drum support cylinder 701 has a mounting bracket 703, on which an encoder is installed. The encoder calculates the lowering depth of the suction tool based on the speed at which the suction rope 704 of the hydraulically driven drum 702 passes.

[0076] In this embodiment, the traction rope 704 passes over the ground pulley 802 at the bottom of the rope rack 801, passes over the top pulley 803 at the top of the rope rack 801, and extends along the axis of the wellhead to the wellhead drainage pipe 806.

[0077] The wellhead remote digital tension meter 804 is used to detect the tension change of the pumping rope 704 in real time. It uses strain gauge sensors to sense the tensile deformation of the pumping rope 704 and converts it into an electrical signal to be transmitted to the control system.

[0078] A pressure transmitter is installed on the wellhead drainage pipeline 806. The pressure transmitter converts the wellhead pressure into a standard electrical signal and transmits it to the control system through the PLC analog input module.

[0079] A temperature sensor is installed on the wellhead drainage pipeline 806. The temperature sensor converts the wellhead temperature signal into an electrical signal and transmits it to the control system through the PLC analog input module.

[0080] Secondly, the hydraulic system 5 in this embodiment integrates multiple hydraulic pressure sensors. The pressure changes of the hydraulic system of the pumping device are monitored by multiple hydraulic force sensors, and the pressure of the hydraulic system 5 is converted into an electrical signal and transmitted to the control system through the PLC analog input module.

[0081] The hydraulic tank 6 integrates a temperature sensor, which monitors the temperature change of the hydraulic system 5 of the pumping device and converts the temperature of the hydraulic system 5 into an electrical signal, which is then transmitted to the control system via the PLC analog input module.

[0082] The control system and data acquisition module in this embodiment mainly include:

[0083] Wellhead Tension Acquisition Device: The wellhead tension acquisition device is used to monitor the tension changes of the 704 drawing rope in real time. This device consists of high-precision strain gauge sensors mounted on the rope guide bracket. The strain gauge sensors detect the tensile deformation of the wire rope and convert it into an electrical signal output. These signals are transmitted to the control system for processing via the PLC's analog input module. Tension data is crucial for determining the load condition during the drawing process, helping operators adjust the drawing speed in a timely manner to avoid overload or breakage accidents.

[0084] Wellhead pressure acquisition device: Used to monitor pressure changes at the wellhead to ensure that the pressure remains within a safe range during pumping. This device consists of a pressure transmitter installed on the pipeline at the wellhead. The pressure transmitter converts the wellhead pressure into a standard electrical signal, such as 4-20mA, and transmits it to the control system via the PLC's analog input module. Changes in wellhead pressure directly reflect the flow state of the downhole fluid; therefore, this device is crucial for preventing accidents such as excessively rapid pumping up, leading to high pressure and wellhead impact. Pressure data can also be used to optimize pumping parameters and improve pumping efficiency.

[0085] Wellhead Temperature Acquisition Device: This device monitors temperature changes at the wellhead to ensure the temperature remains within a reasonable range during pumping. It consists of a resistance temperature detector (RTD) sensor installed on the wellhead drainage pipeline. The temperature sensor converts the wellhead temperature into an electrical signal, which is transmitted to the control system via the PLC's analog input module. Changes in wellhead temperature can affect the physical properties of the pumped medium, such as viscosity and density, thus impacting pumping efficiency. Therefore, real-time monitoring of the wellhead temperature helps optimize pumping parameters and ensures the safety and stability of the pumping process.

[0086] The dredging depth measuring device is used to accurately measure the lowering depth of the dredging tool, ensuring accurate depth control during the dredging process. This device consists of an encoder, installed on the intelligent rope guide system of the dredging winch. The encoder calculates the lowering depth of the dredging tool based on the speed of the dredging rope 704 passing through the winch. This depth data is crucial for determining the position of the dredging tool and helps operators avoid working at excessive depth. The depth data can also be used to optimize dredging parameters and improve dredging efficiency.

[0087] Hydraulic pressure acquisition device: This device monitors pressure changes in the hydraulic system 5 of the pumping unit to ensure its normal operation. It consists of hydraulic pressure sensors installed at key points within the hydraulic system 5. These sensors convert the pressure of the hydraulic system 5 into electrical signals, which are then transmitted to the control system via the PLC's analog input module. The pressure of the hydraulic system 5 directly affects the operating performance of the pumping unit; therefore, real-time monitoring of the hydraulic pressure helps to promptly detect faults in the hydraulic system 5, preventing pumping interruptions or equipment damage due to system malfunction.

[0088] Equipment Hydraulic Temperature Acquisition Device: This device monitors the temperature changes of the hydraulic system 5 in the pumping unit, ensuring that the temperature of the hydraulic system 5 remains within a reasonable range. The device consists of a temperature sensor installed on the oil tank of the hydraulic system 5. The temperature sensor converts the temperature of the hydraulic system 5 into an electrical signal, which is then transmitted to the control system 5 via the analog input module of the PLC. Excessive or insufficient temperature in the hydraulic system 5 will affect its working efficiency and service life; therefore, real-time monitoring of the hydraulic temperature helps optimize the operating parameters of the hydraulic system 5 and extend the equipment's lifespan.

[0089] Automatic Control and Manual Setting Interaction Actuator: This actuator, the central component of the pumping unit's PLC control system, seamlessly switches between automatic control and manual intervention. It consists of human-machine interface devices such as a touchscreen, buttons, and knobs, and is installed on the control cabinet's operation panel. Operators can set pumping parameters, such as pumping speed, pumping depth, and pumping time, via the touchscreen or buttons. The PLC control system automatically adjusts these parameters based on real-time data acquisition, ensuring the safety and efficiency of the pumping process. When manual intervention is required, operators can manually control the pumping unit's operation via the touchscreen or buttons, ensuring timely action can be taken in special circumstances.

[0090] Operating status recorder: Used to record the operating status and historical data of the pumping unit, providing a basis for subsequent fault analysis and maintenance. This recorder consists of a data storage module and a communication interface, and is installed in the PLC control system. The data storage module can record the operating parameters of the pumping unit in real time, such as wellhead pressure, wellhead temperature, pumping depth, hydraulic pressure, and hydraulic temperature. The communication interface is used to upload the recorded data to a remote monitoring system, allowing operators to view and analyze it at any time. The introduction of the operating status recorder not only improves the intelligence level of the pumping unit but also provides strong support for long-term maintenance and optimization of the equipment.

[0091] Based on the composition of the control system described above, the control logic of the PLC programmable control module in this embodiment mainly includes the following steps:

[0092] Initialization: Before system startup, the PLC control system performs a self-check on each component to ensure they are in normal working order. The self-check includes verifying sensor connection status, actuator operation, and communication interface connectivity. After the self-check, the PLC initializes the control system according to preset parameters, including pumping speed, pumping depth, and pumping time. These initialization settings can be adjusted based on different working environments and requirements to ensure the pumping device operates at its optimal condition.

[0093] Data Acquisition and Processing: The PLC control system collects the operating parameters of the pumping device in real time through sensors such as wellhead tension acquisition devices, wellhead pressure acquisition devices, wellhead temperature acquisition devices, pumping depth measurement devices, equipment hydraulic control pressure acquisition devices, and equipment hydraulic control temperature acquisition devices. The acquired data undergoes preprocessing such as filtering, noise reduction, and data format conversion before being transmitted to the PLC's central processing unit for further analysis. The purpose of preprocessing is to ensure the accuracy and validity of the data and avoid data anomalies caused by external interference or sensor malfunctions.

[0094] Data Analysis and Judgment: The PLC control system performs in-depth analysis of the pre-processed data, comparing it with preset safety thresholds to determine whether the pumping device is operating normally. For example, when the wellhead pressure exceeds the preset safety upper limit, the PLC will trigger an alarm mechanism and take corresponding protective measures, such as reducing the pumping speed or stopping the pumping operation. Similarly, when parameters such as wellhead temperature, hydraulic pressure, and hydraulic temperature exceed safe ranges, the PLC will also take corresponding measures to ensure the safe operation of the pumping device. The results of the data analysis are not only used for real-time control but are also recorded in the operating condition recorder, providing a basis for subsequent fault analysis and maintenance.

[0095] Control Strategy Adjustment: Based on data analysis results, the PLC control system dynamically adjusts the control strategy of the pumping device. For example, during pumping, if a sudden increase in wellhead pressure is detected, the PLC will automatically reduce the pumping speed to prevent a blowout. Similarly, if the hydraulic system temperature is detected to be too high, the PLC will activate the cooling system to lower the hydraulic system temperature and ensure its normal operation. This control strategy adjustment, based on real-time data feedback, effectively addresses various complex operating conditions, ensuring the safety and efficiency of the pumping device.

[0096] Fault Handling and Recording: When the PLC control system detects a fault, it will immediately take corresponding measures, such as cutting off the power supply and starting backup equipment, to prevent the fault from escalating and causing more serious consequences. The PLC will automatically record the time, type, and cause of the fault and store this information in the operating condition recorder. Fault recording not only facilitates subsequent troubleshooting and maintenance but also helps operators summarize experience, optimize the operating parameters of the pumping unit, and improve the reliability and service life of the equipment.

[0097] Human-Machine Interaction and Remote Monitoring: The PLC control system is equipped with an actuator that combines automatic control with manual setting, allowing operators to manually control the pumping unit via touchscreen or buttons. This human-machine interaction not only improves operational flexibility but also ensures timely action in special circumstances. The PLC control system also supports remote monitoring, allowing operators to access the pumping unit's operating status and historical data via network, enabling real-time monitoring and remote management. The introduction of remote monitoring not only enhances the pumping unit's intelligence but also facilitates cross-regional management.
