Description

Technical Field

[0001] This invention relates to the field of mechanical control technology, and in particular to an intermittent pumping control method, device, electronic equipment, and storage medium for oil wells. Background Technology

[0002] As oil wells are continuously exploited, insufficient fluid supply is a common problem. Oilfields, under limited water injection conditions, struggle to ensure timely energy replenishment. Pumping units cannot adjust in real-time according to fluctuations in the downhole fluid level. The actual fluid supply capacity of the oil well is mismatched with the output power of the pumping unit motor, resulting in uncoordinated supply and drainage. This causes ineffective wear on both surface and downhole equipment, leading to severe uneven wear between the tubing and casing, increasing the frequency of 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 pumping units. It can not only effectively improve pump efficiency and save energy, but also greatly reduce the wear and tear on surface and downhole equipment, achieving the effect of cost reduction and revenue increase. However, at present, intermittent pumping schemes mainly rely on manual experience to set pumping and stopping periods, resulting in extensive management, low level of intelligence, and difficulty in achieving precise intermittent pumping. Summary of the Invention

[0004] This invention provides a method, apparatus, equipment, and storage medium for intermittent pumping control of oil wells, which solves the problem of low precision in intermittent pumping control of oil wells.

[0025] Example 1

[0026] Figure 1 This is a flowchart illustrating an intermittent pumping control method for oil wells according to Embodiment 1 of the present invention. This embodiment is applicable to intermittent pumping scenarios in oil wells. The method can be executed by an intermittent pumping control device for the oil well, which can be implemented in 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 the flow measurement device.

[0028] This scheme can be executed by the intermittent pumping control system of the oil well. The intermittent pumping control system can detect flow measurement trigger events. The flow measurement trigger event can be the start of the measurement cycle, the start of the first intermittent pumping period, the end of the previous intermittent pumping period, or the shutdown of the pumping equipment or the pumping reaching the preset shutdown time.

[0029] The intermittent pumping control system can use a clock to determine whether a flow measurement trigger event has occurred. 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. This 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 requires intermittent pumping. The fluid flow information can include the flow rates of fluids such as oil, gas, and water, and can also include information such as temperature and fluid composition.

[0030] S120. Based on the flow measurement trigger event, the fluid flow information, and the predetermined reference flow range of the target fluid, control the pumping equipment to intermittently pump the target oil well.

[0031] By determining the type of flow measurement trigger event, the intermittent pumping control system can identify the flow rate of the target fluid from the fluid flow information. Based on the flow rate of the target fluid and a pre-determined reference flow rate range, it determines the pumping frequency of the pumping equipment and thus controls the pumping equipment to intermittently pump from the target oil well. The target fluid can be oil, water, or gas.

[0032] In this scheme, optionally, before controlling the pumping equipment to intermittently pump the target oil well based on the flow measurement trigger event, the fluid flow information, and the pre-determined reference flow range of the target fluid, the method further includes:

[0033] If the target oil well is detected to meet 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 equipment;

[0034] Based on the fluid flow rate information within a preset time period, generate the flow rate curve of the target fluid;

[0035] Based on the flow rate curve, determine the reference flow rate range of the target fluid.

[0036] For oil wells in the later stages of production, insufficient formation energy, weakened fluid supply capacity, and uncoordinated supply and drainage result in lower pumping equipment fill rates and decreased pumping efficiency. Therefore, obtaining the reference flow range for the target fluid requires a preset shutdown time for the target oil well. The flow curve acquisition conditions may include the target oil well being shut down for the preset time, or the flow curve showing a downward trend. When the flow curve acquisition conditions are met, the intermittent pumping control system can acquire fluid flow information at a preset acquisition frequency within the preset time using a flow measurement device. Based on the acquisition time and the corresponding fluid flow rate, the intermittent pumping control system can plot 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 range of the target fluid based on these characteristics. For example, the intermittent pumping control system can calculate the slope between every two points on the flow curve, and use the flow values ​​corresponding to the endpoints of the line segment with the largest absolute slope as the endpoint values ​​of the reference flow range, thereby obtaining the reference flow range of the target fluid.

[0038] The above scheme helps to ensure the stability and accuracy of the target fluid flow rate assessment within the reference flow range, provides a reliable basis for determining the pumping frequency, and thus enables scientific intermittent pumping of the target oil well, thereby improving production efficiency.

[0039] The technical solution of this invention, upon detecting a flow measurement trigger event, utilizes a flow measurement device to acquire fluid flow information of the target oil well. Based on the flow measurement trigger event, the fluid flow information, and a pre-determined reference flow range for the target fluid, it controls the pumping equipment to intermittently pump from the target oil well. This technical solution solves the problem of low precision in intermittent pumping control of oil wells, and can improve the working efficiency of the pumping unit and reduce oil well extraction costs while ensuring oil well production.

[0040] Example 2

[0041] Figure 2 This is a flowchart of an intermittent pumping control method for oil wells provided in Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Figure 2 As shown, the method includes:

[0042] S201. Determine whether a flow measurement trigger event has occurred.

[0043] In this scheme, the flow measurement trigger event includes three situations: the start of the first intermittent pumping period, the end of the previous intermittent pumping period, and the shutdown of the pumping equipment or the reaching of a preset shutdown duration. The intermittent pumping control system can determine whether a flow measurement trigger event has occurred at the current moment, that is, whether the current moment is the start of the first intermittent pumping period, the end of the previous intermittent pumping period, or the shutdown of the pumping equipment or the reaching of a preset shutdown duration. If no flow measurement trigger event has occurred, the system continues to determine whether a flow measurement trigger event has occurred at the current moment according to a preset judgment cycle, and executes S201. If any of the above three situations of a flow measurement trigger event occurs, S202 is executed.

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

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

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

[0047] The intermittent sampling control system can determine whether the flow measurement trigger event marks the start of the first intermittent sampling period. If the flow measurement trigger event marks the start of the first intermittent sampling period, then execute S204. If the flow measurement trigger event does not mark the start of the first intermittent sampling period, then execute S208.

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

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

[0050] During the first intermittent pumping period, the intermittent pumping control system can determine whether the target fluid flow rate is within the reference flow rate range, 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 range, then S205 is executed. If the target fluid flow rate is not within the reference flow rate range, then S206 is executed to determine whether the target fluid flow rate is less than or equal to the first flow rate endpoint value.

[0051] S205. Based on the first preset intermittent pumping time, control the pumping equipment to intermittently pump the target oil well.

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

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

[0054] Understandably, the first flow rate endpoint value can be the left endpoint value of the reference flow rate range. If the target fluid flow rate is not within the reference flow rate range, the intermittent pumping control system can continue to determine whether the target fluid flow rate is less than or equal to the first flow rate endpoint value, i.e., 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 rate is less than or equal to the first flow rate endpoint value, then S207 is executed. If the target fluid flow rate is greater than or equal to the second flow rate endpoint value, it indicates that the fluid supply of the target oil well is sufficient, 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 duration.

[0055] S207. Control the shutdown or oscillation of the oil pumping equipment.

[0056] If the target fluid flow rate is less than or equal to the first flow rate endpoint value, the intermittent pumping control system can shut down the pumping equipment. In low-temperature production environments, the intermittent pumping control system can control the pumping equipment to operate continuously while pumping, thus preventing the fluid level in the target 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 start 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, then S209 is executed; if the flow measurement trigger event is not the end of the previous intermittent pumping period, then the flow measurement trigger event is the shutdown of the pumping equipment or the swing pumping reaching the preset shutdown duration, and the system returns to execute S201.

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

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

[0061] S210. According to the second preset intermittent pumping time, control the pumping equipment to intermittently pump 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 rate 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 average value at the endpoints.

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

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

[0066] S212. Based on the third preset intermittent pumping time, control the pumping equipment to intermittently pump the target oil well.

[0067] 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 average value at the endpoints, 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 scheme can dynamically adjust the intermittent pumping strategy based on the fluid flow information of the target oil well, which is conducive to achieving refined intermittent pumping of oil wells, reducing extraction energy consumption, and improving extraction efficiency.

[0069] The technical solution of this invention, upon detecting a flow measurement trigger event, utilizes a flow measurement device to acquire fluid flow information of the target oil well. Based on the flow measurement trigger event, the fluid flow information, and a pre-determined reference flow range for the target fluid, it controls the pumping equipment to intermittently pump from the target oil well. This technical solution solves the problem of low precision in intermittent pumping control of oil wells, and can improve the working efficiency of the pumping unit and reduce oil well extraction costs while ensuring oil well production.

[0088] If the flow measurement trigger event is the end of the previous intermittent pumping period, and the target fluid flow rate in the fluid flow information is less than or equal to the endpoint average, then the pumping equipment is controlled to intermittently pump the target oil well according to the third preset intermittent pumping duration; wherein, the waiting time in the third preset intermittent pumping duration is greater than the waiting time in the first preset intermittent pumping duration.

[0089] Based on the above scheme, optionally, the flow measurement trigger event also includes the shutdown of the pumping equipment or the pumping reaching a preset shutdown duration.
