Description

Technical Field

[0002] With the continuous exploitation of oil wells, the phenomenon of insufficient fluid supply is common inside the oil wells. It is difficult to ensure the timely replenishment of energy under limited water injection conditions. The pumping unit cannot make real-time adjustments according to the fluctuation of the downhole liquid level. The actual fluid supply capacity of the oil well does not match the output power of the pumping unit motor, and the supply and discharge are not coordinated, resulting in ineffective wear of ground equipment and downhole equipment, causing serious eccentric wear between rods, pipes, and casings, increasing the frequency of oil well pump inspections and the cost of oil well exploitation.

[0003] Intermittent oil production is an effective way to solve the problem of inefficient operation of oil pumps. It can not only effectively improve pump efficiency and save electricity, but also greatly reduce the wear of surface equipment and downhole equipment, achieving the effect of reducing costs and increasing revenue. However, the current oil well intermittent pumping scheme mainly relies on manual experience to set the pumping and stop periods, with extensive management and low intelligence, making it difficult to achieve refined intermittent pumping.

[0025] Embodiment 1

[0026] Figure 1 A flowchart of an intermittent pumping control method for an oil well is provided for the first embodiment of the present invention. This embodiment is applicable to intermittent pumping scenarios of oil wells. The method can be executed by an intermittent pumping control device for an oil well, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0027] S110: If a flow measurement trigger event is detected, the fluid flow information of the target oil well is obtained through a flow measurement device.

[0028] This solution can be executed by the intermittent pumping control system of the oil well, and the intermittent pumping control system can detect the flow measurement trigger event, wherein the flow measurement trigger event can be the beginning of the measurement cycle, the beginning of the first intermittent pumping period, the end of the previous intermittent pumping period, or the shutdown of the pumping equipment or the swing pumping reaching a preset suspension time.

[0029] The intermittent pumping control system can determine whether a flow measurement trigger event occurs by clock timing. If a flow measurement trigger event is detected, the fluid flow information of the target oil well can be collected through a flow measurement device. The flow measurement device can be a flow meter, such as a magnetic resonance multiphase flow meter. The target oil well can be an oil well that has reached the late stage of production and needs to be intermittently pumped. The fluid flow information can include flow information of fluids such as oil, gas and water, and can also include information such as temperature and fluid proportion.

[0030] S120: Control the pumping equipment to perform intermittent pumping on the target oil well according to the flow measurement trigger event, the fluid flow information, and a predetermined reference flow interval of the target fluid.

[0031] By determining the type of flow measurement trigger event, the intermittent pumping control system can determine the flow information of the target fluid in the fluid flow information, determine the pumping frequency of the pumping equipment according to the flow information of the target fluid and the predetermined reference flow interval of the target fluid, and then control the pumping equipment to perform intermittent pumping on the target oil well. The target fluid can be oil, water, or gas.

[0032] In this solution, optionally, before controlling the pumping equipment to perform intermittent pumping on the target oil well according to the flow measurement trigger event, the fluid flow information and a predetermined reference flow interval of the target fluid, the method further includes:

[0033] If it is detected that the target oil well meets the preset flow curve acquisition conditions, the fluid flow information of the target oil well within the preset time period is obtained through the flow measurement device;

[0034] Generate a flow curve of the target fluid according to the fluid flow information within a preset time period;

[0035] According to the flow curve, a reference flow interval of the target fluid is determined.

[0036] For oil wells in the late stage of production, the formation energy is insufficient, the fluid supply capacity is weakened, the supply and discharge are not coordinated, the pumping equipment is less full, and the pumping efficiency is reduced. Therefore, to obtain the reference flow interval of the target fluid, it is necessary to preset the shutdown time of the target oil well. The flow curve acquisition conditions may include that the target oil well has been shut down for a preset time, and may also include that the flow curve is on a downward trend. When the flow curve acquisition conditions are met, the intermittent pumping control system can obtain fluid flow information through the flow measurement equipment within a preset time according to a preset acquisition frequency. According to the acquisition time and the fluid flow corresponding to the acquisition time, the intermittent pumping control system can draw the flow curve of the target fluid.

[0037] The intermittent pumping control system can analyze the flow curve, identify flow change characteristics, and determine the reference flow interval of the target fluid based on the flow change characteristics. For example, the intermittent pumping control system can calculate the slope between every two points in the flow curve, and use the flow values ​​corresponding to the two endpoints of the line segment with the largest absolute value of the slope as the endpoint values ​​of the reference flow interval, thereby obtaining the reference flow interval of the target fluid.

[0038] The above scheme is conducive to ensuring the stability and accuracy of the reference flow interval for the target fluid flow assessment, providing a reliable basis for determining the pumping frequency, and then achieving scientific pumping of the target oil wells and improving mining efficiency.

[0039] The technical solution of the embodiment of the present invention, when a flow measurement trigger event is detected, uses a flow measurement device to obtain fluid flow information of a target oil well, and controls the pumping equipment to perform intermittent pumping on the target oil well according to the flow measurement trigger event, the fluid flow information, and a predetermined reference flow interval of the target fluid. This technical solution solves the problem of low refinement of intermittent pumping control of oil wells, and can improve the working efficiency of the pumping unit and reduce the cost of oil well exploitation while ensuring the output of the oil well.

[0040] Embodiment 2

[0041] Figure 2 This is a flow chart of an oil well intermittent pumping control method provided in the second embodiment of the present invention. This embodiment is based on the above embodiment and is refined. Figure 2 As shown, the method includes:

[0042] S201: Determine whether a flow measurement trigger event occurs.

[0043] In this solution, the flow measurement trigger event includes three situations: the beginning of the first intermittent pumping period, the end of the previous intermittent pumping period, and the shutdown of the pumping equipment or the swing pumping reaching the preset suspension time. The intermittent pumping control system can determine whether a flow measurement trigger event occurs at the current moment, that is, whether the current moment is the beginning of the first intermittent pumping period, whether the current moment is the end of the previous intermittent pumping period, and whether the current moment is the shutdown of the pumping equipment or the swing pumping reaching the preset suspension time. If no flow measurement trigger event occurs, continue to determine whether a flow measurement trigger event occurs at the current moment according to the preset judgment cycle, and execute S201. If any of the above three situations occur, execute S202.

[0044] S202: Obtain fluid flow information of the target oil well through a flow measurement device.

[0045] If a flow measurement trigger event occurs, the fluid flow information of the target oil well is collected through the flow measurement equipment.

[0046] S203: Determine whether the flow measurement trigger event is the start of the first intermittent sampling period.

[0047] The intermittent pumping control system can determine whether the flow measurement trigger event is the start of the first intermittent pumping period, and if the flow measurement trigger event is the start of the first intermittent pumping period, S204 is executed. If the flow measurement trigger event is not the start of the first intermittent pumping period, S208 is executed.

[0048] It should be noted that, in a feasible solution, if the flow measurement triggering event is the beginning of the first intermittent pumping period, the intermittent pumping control system may also execute S206, or execute S204 and S206 simultaneously.

[0049] S204: Determine whether the target fluid flow rate is within a reference flow rate range.

[0050] In the first intermittent pumping period, the intermittent pumping control system can determine whether the target fluid flow rate is within the reference flow rate interval, that is, whether the current target fluid flow rate of the target oil well can meet the pumping conditions of the pumping equipment. If the target fluid flow rate is within the reference flow rate interval, S205 is executed. If the target fluid flow rate is not within the reference flow rate interval, S206 is executed to determine whether the target fluid flow rate is less than or equal to the first flow endpoint value.

[0051] S205. According to the first preset intermittent pumping time, control the oil pumping equipment to perform intermittent pumping on the target oil well.

[0052] The first preset intermittent pumping time may include a pumping time and a waiting time, wherein the waiting time may be 0. If the target fluid flow rate is within the reference flow rate interval, the intermittent pumping control system may control the pumping equipment to intermittently pump the target oil well according to the first preset intermittent pumping time until the first intermittent pumping period ends. It should be noted that each intermittent pumping period may include one or more preset intermittent pumping time periods.

[0053] S206: Determine whether the target fluid flow rate is less than or equal to the first flow rate endpoint value.

[0054] It can be understood that the first flow endpoint value can be the left endpoint value of the reference flow interval. If the target fluid flow is not within the reference flow interval, the intermittent pumping control system can continue to determine whether the target fluid flow is less than or equal to the first flow endpoint value, that is, whether the fluid supply capacity of the target oil well is too poor, resulting in low efficiency of the pumping equipment. If the target fluid flow is less than or equal to the first flow endpoint value, execute S207. If the target fluid flow is equal to or equal to the second flow endpoint value, it means that the target oil well has sufficient fluid supply, and the intermittent pumping control system can return to execute S201 to control the pumping equipment to intermittently pump the target oil well according to the second preset intermittent pumping time.

[0055] S207, controlling the oil pumping equipment to shut down or swing pumping.

[0056] If the target fluid flow rate is less than or equal to the first flow endpoint value, the intermittent pumping control system can control the pumping equipment to shut down. In a production scenario with a lower temperature, the intermittent pumping control system can control the pumping equipment to continue pumping without stopping, so as to prevent the liquid surface in the target oil well from freezing while stopping pumping.

[0057] S208: Determine whether the flow measurement trigger event is the end of the previous intermittent sampling period.

[0058] If the flow measurement trigger event is not the beginning of the first intermittent pumping period, the intermittent pumping control system can continue to determine whether the flow measurement trigger event is the end of the previous intermittent pumping period. If the flow measurement trigger event is the end of the previous intermittent pumping period, execute S209. If the flow measurement trigger event is not the end of the previous intermittent pumping period, the flow measurement trigger event is the shutdown of the pumping equipment or the swing pumping reaches the preset stop time, and return to execute S201.

[0059] S209: Determine whether the target fluid flow rate is greater than or equal to the second flow rate endpoint value.

[0060] If the target fluid flow rate is greater than or equal to the second flow endpoint value, it means that the target oil well has sufficient fluid supply, and the pumping time can be increased based on the first preset interval pumping time, and S210 is executed. If the target fluid flow rate is not greater than and not equal to the second flow endpoint value, S211 is executed.

[0061] S210. According to a second preset intermittent pumping time, control the oil pumping equipment to perform intermittent pumping on the target oil well.

[0062] Wherein, the waiting time in the second preset intermittent pumping time is less than the waiting time in the first preset intermittent pumping time. If the target fluid flow rate is greater than or equal to the second flow endpoint value, the intermittent pumping control system can control the pumping equipment to intermittently pump the target oil well according to the second preset intermittent pumping time.

[0063] S211. Determine whether the target fluid flow rate is less than or equal to the endpoint average value.

[0064] If the target fluid flow is not greater than and equal to the second flow endpoint value, the intermittent pumping control system can determine whether the target fluid flow is less than or equal to the endpoint average value, wherein the endpoint average value can be the average value of the first flow endpoint value and the second flow endpoint value.

[0065] If the target fluid flow rate is less than or equal to the endpoint average value, S212 is executed. If the target fluid flow rate is not less than and not equal to the endpoint average value, the intermittent pumping control system can return to execute S204.

[0066] S212: Control the oil pumping equipment to perform intermittent pumping on the target oil well according to the third preset intermittent pumping time.

[0067] Wherein, the waiting time in the third preset intermittent pumping time is longer than the waiting time in the first preset intermittent pumping time. If the target fluid flow rate is less than or equal to the endpoint average, the intermittent pumping control system can control the pumping equipment to intermittently pump the target oil well according to the third preset intermittent pumping time.

[0068] This solution can dynamically adjust the inter-pumping strategy according to the fluid flow information of the target oil well, which is conducive to realizing refined inter-pumping of oil wells, reducing mining energy consumption and improving mining efficiency.

[0069] The technical solution of the embodiment of the present invention, when a flow measurement trigger event is detected, uses a flow measurement device to obtain fluid flow information of a target oil well, and controls the pumping equipment to perform intermittent pumping on the target oil well according to the flow measurement trigger event, the fluid flow information, and a predetermined reference flow interval of the target fluid. This technical solution solves the problem of low refinement of intermittent pumping control of oil wells, and can improve the working efficiency of the pumping unit and reduce the cost of oil well exploitation while ensuring the output of the oil well.
