Description

Technical Field

[0001] This invention relates to a power boosting equipment, and more particularly to an automatic control system and control method for such equipment, belonging to the field of oil and gas development technology. Background Technology

[0002] Energy-enhancing injection technology is mainly used in the development of high-pressure, low-porosity, and low-permeability oil wells. The injection medium is clean water, requiring large injection volumes, high pressures, long working cycles, and continuous pump output. Energy-enhancing injection equipment uses an engine as a power source, and controls the plunger pump strokes by adjusting the engine speed and torque converter gear, thereby adjusting the plunger pump's output displacement and pressure.

[0003] Currently, most systems automatically collect data on engine speed, torque converter gear, and plunger pump displacement and pressure, displaying it centrally on a control panel. Operators rely on experience to adjust the engine speed and torque converter gear to control the plunger pump's output displacement and pressure. However, adjusting engine speed, torque converter gear, plunger pump displacement, plunger pump pressure, and connecting valve opening are all manual operations, requiring a high level of professional skill and being cumbersome. Furthermore, if operators do not adjust the engine speed correctly when changing gears, the efficiency of the power booster equipment cannot be guaranteed to be optimal, potentially generating excessive impact force and damaging the torque converter and other linked equipment. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings in the operation of existing power boosting equipment, the present invention provides an automatic control system and control method for power boosting equipment.

[0005] The technical solution adopted by this invention to solve its technical problem is: an automatic control method for energy-boosting equipment, including an engine, a torque converter, and a connecting valve, with a preset operating pressure limit value for the energy-boosting equipment, and the automatic control steps based on the preset operating pressure limit value are as follows:

[0006] P1. Perform engine speed detection I, torque converter gear detection I, and connecting valve opening detection I.

[0007] If the engine is idling, the torque converter is in neutral (N) gear, and the connecting valve is open, the energy booster equipment enters automatic operation mode; otherwise, the control system will adjust the engine speed, torque converter gear, and connecting valve opening until the energy booster equipment enters automatic operation mode.

[0008] P2, in automatic operation mode

[0009] Set the torque converter to gear 1 and close the connecting valve;

[0010] Perform valve opening test II, and control the valve to be closed while performing working pressure test I;

[0011] P3. Determine if the working pressure is less than the operating pressure limit.

[0012] If the working pressure is greater than or equal to the operating pressure limit, the system will issue an alarm signal, the engine will stop running, the torque converter will be put into neutral (N) gear, and the connecting valve will open.

[0013] If the working pressure is less than the operating pressure limit, increase the engine speed to the rated speed and perform working pressure test II.

[0014] P4. Working pressure test II: Determines whether the working pressure is less than the operating pressure limit.

[0015] If the working pressure is less than the operating pressure limit, reduce the engine speed to the torque converter shift speed, shift the torque converter up, and increase the engine speed to the rated speed to perform working pressure test II.

[0016] If the working pressure is greater than or equal to the operating pressure limit, determine whether the working pressure is greater than 101% of the operating pressure limit.

[0017] P5. Determine whether the working pressure exceeds 101% of the operating pressure limit.

[0018] If the working pressure limit is 100% ≤ working pressure ≤ 101% of the working pressure limit, perform working pressure test II again and repeat step P4.

[0019] If the working pressure is greater than 101% of the operating pressure limit, the engine speed will be reduced quantitatively, and engine speed detection II will be performed to determine whether the engine speed is less than or equal to the torque converter shift speed.

[0020] If the engine speed is less than or equal to the torque converter shift speed, downshift the torque converter and perform working pressure test II again, repeating step P4.

[0021] If the engine speed is greater than the torque converter shift speed, return to working pressure detection II and execute steps P4 and P5 until the working pressure limit is 100% ≤ working pressure ≤ working pressure limit 101%.

A preset operating displacement limit value for the energy-boosting equipment is defined, and the automatic control steps based on this preset operating displacement limit value are as follows:

[0024] D1. Perform engine speed test I, torque converter gear test I, and connecting valve opening test I.

[0025] If the engine is idling, the torque converter is in neutral (N) gear, and the connecting valve is open, the energy booster equipment enters automatic operation mode; otherwise, the control system will adjust the engine speed, torque converter gear, and connecting valve opening until the energy booster equipment enters automatic operation mode.

[0032] D4. Working Displacement Detection II: Determines whether the working displacement is less than the operating displacement limit.

[0033] If the working displacement is less than the operating displacement limit, reduce the engine speed to the torque converter shift speed, shift the torque converter up, and increase the engine speed to the rated speed to perform working displacement test II.

[0038] If the engine speed is less than or equal to the torque converter shift speed, downshift the torque converter and perform the displacement test II again, repeating step D4.

[0039] If the engine speed is greater than the torque converter shift speed, return to the working displacement detection II and execute steps D4 and D5 until the working displacement limit value 100% ≤ working displacement ≤ working displacement limit value 101%;

[0040] Repeat step D4, or repeat steps D4 and D5, to complete automatic control under the preset operating displacement limit.

[0041] Furthermore, in the engine speed detection I, if the engine is not idling, the control system will set the engine to idle and then re-perform the detection.

[0042] Furthermore, in the torque converter gear position detection I, if the torque converter is not in gear N, the control system will set the torque converter gear to gear N and then re-perform the detection.

[0043] Furthermore, in the valve opening detection I, if the valve is not open, the control system will open the valve and then re-perform the detection.

[0044] Furthermore, in the connecting valve opening detection II, if the connecting valve is not closed, the control system will close the connecting valve and then continue with the connecting valve opening detection II.

[0098] Repeat step D4, or repeat steps D4 and D5, to complete automatic control under the preset operating displacement limit.

[0099] During the operation of the capacity boosting equipment, automatic control of the equipment can be achieved by adopting an automatic control method based on a preset operating pressure limit or an automatic control method based on a preset operating displacement limit.

[0100] Furthermore, in steps D1, if the engine speed does not meet the idling condition in engine speed detection I, the control system will set the engine to idle and then re-detect; if the torque converter gear does not meet the gear N condition in torque converter gear detection I, the control system will set the torque converter gear to gear N and then re-detect; if the connecting valve opening condition is not met in connecting valve detection I, the control system will open the connecting valve and then re-detect.

[0101] Furthermore, in steps P2 and D2, if the connecting valve is not closed during the connecting valve opening detection II, the control system will close the connecting valve and then continue with the connecting valve opening detection II.

[0102] In steps P1 and D1, the engine idle speed is 1000 rpm.

[0104] In steps P4 and D4, the engine speed is 1500 rpm when the torque converter shifts gears.

[0105] In steps P5 and D5, the quantitative reduction of engine speed is 50 rpm per step. When the engine speed is greater than the torque converter shift speed (1500 rpm), the quantitative reduction of engine speed is carried out in steps (50 rpm), each time decreasing by 50 rpm, until the torque converter shift is completed.

[0108] The execution module 4 includes engine speed control, torque converter gear control, and connecting valve opening control.

[0109] When the limiting module 3 includes a preset operating pressure limit value, the detection module 2 detects data including engine speed, torque converter gear, connecting valve opening, and operating pressure; the control module 1 analyzes and judges the detection data acquired in real time by the detection module 2 according to the preset operating pressure limit value, and the execution module 4 executes the engine, torque converter, and connecting valve operation commands issued by the control module 1.

[0111] In this invention, the power-enhancing throughput equipment can be automatically controlled based on either a preset operating pressure limit or a preset operating displacement limit. Furthermore, both preset operating pressure and preset operating displacement limits can be set in the limiting module. When two control systems based on these limits are included, one can be selected for use; if one control system malfunctions, the other can be activated to ensure the continuous operation of the power-enhancing throughput equipment.

[0112] This invention discloses an automatic control system and method for energy-boosting throughput equipment. Based on preset operating pressure or displacement limits, the system collects real-time data such as engine speed, torque converter gear, connecting valve opening, operating pressure, or operating displacement and transmits this data to the control system.
