Description

Technical Field

[0001] The present invention relates to the field of oil well exploitation, and in particular to a storage medium, an oil well operation remote control method, device and equipment. Background Art

[0002] Peak-valley electricity price is also called "time-of-use electricity price". The peak-valley electricity price system is an electricity price system that calculates electricity charges according to peak electricity consumption and valley electricity consumption. During peak electricity consumption, that is, the period of tight power supply, the unit electricity price is higher; during valley electricity consumption, that is, the period of sufficient power supply, the unit electricity price is lower. Therefore, the electricity cost of oil wells will also be lower during valley electricity consumption.

[0003] With the continuous development of oil fields, the liquid production of oil wells will show a downward trend due to many factors such as formation blockage, near-well pollution, insufficient formation fluid supply capacity, and high water-cut production. Oil wells whose liquid production capacity drops to a set threshold are called low-yield and low-efficiency wells.

[0004] In the prior art, the oil wells are generally put into production by maximizing the use of off-peak electricity consumption periods to reduce the unit electricity cost of the oil wells.

[0005] The inventors have found through research that the production planning method for low-yield and low-energy wells in the prior art has at least the following defects:

[0006] The liquid level recovery rate of low-yield and low-efficiency wells is lower than the oil production rate. Long-term continuous production of oil wells will instead cause a decrease in the overall oil production efficiency.

[0022] The valley-peak electricity price array unit is used to generate an array C for representing the corresponding relationship between electricity price and electricity price period according to the valley-peak electricity price system: C = [c1, c2, ..., c n ], where c1, c2…, c n is the electricity price in each electricity price period, and n is the number of electricity price periods;

[0023] The planning model generation unit is used to generate an operation planning model with the goal of minimizing electricity costs:

[0024]

[0025] The constraints of the operation planning model include:

[0026] Total running time constraints: And, liquid production constraint:

[0027] Among them, x i is the target oil well in the i-th electricity price period c i The running time under is the target daily liquid production of the target oil well, is the average daily production of the past preset days; v is the target hourly liquid production, A is the unit liquid production enhancement coefficient, ranging from 1 to 1.2;

[0028] The operation plan generating unit can solve the x of each electricity price period according to the operation plan model. i Generate an operation time schedule for the target oil well in the next 24 hours;

[0030] Preferably, the present invention further comprises:

[0031] A monitoring image acquisition unit, used for acquiring a monitoring image of the target oil well in real time;

[0032] The current operating condition recognition unit is used to determine the current operating condition of the target oil well through image recognition according to the monitoring image, and the current operating condition includes the start and stop state of the target oil well.

[0033] On the other hand, an oil well operation remote control device is provided, which includes a computer program stored on a medium, and the computer program includes program instructions. When the program instructions are executed by a computer, the computer executes the methods described in the above aspects and achieves the same technical effects.

[0034] On the other hand, a storage medium is provided on which a computer program is stored. When the computer program is executed by a processor, each step of the remote control method for oil well operation as described in any one of the above items is implemented.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] In the present invention, on the one hand, the average value of the all-day production in the past few days is used as a reference for the all-day liquid production of planned production (i.e., the target daily liquid production); on the other hand, the liquid production per unit hour is calculated according to the target daily liquid production through a preset algorithm as the target hourly liquid production; in this way, after establishing an operation plan model with the minimization of electricity costs as the goal, constraints based on the target hourly liquid production and the target daily liquid production can be set to obtain a combination strategy for the operating time in each electricity price period that can minimize the all-day electricity cost while ensuring a higher all-day liquid production; thereby, the overall oil production efficiency of the oil well is improved under the premise of minimizing the electricity cost.

[0039] Preferably, in the present invention, infrared light can be emitted to the image acquisition device by setting an infrared emitting device in the near field of the oil pump. Since the infrared light path is set at the position when the donkey head of the oil pump reaches the highest position, when the donkey head moves down, it no longer blocks the infrared light path, and the infrared light will generate an infrared signal in the image data. After a sprint cycle is completed, the donkey head will block the infrared light path again, so that a periodic infrared signal will be generated in the image data, and the current sprint data of the oil pump can be obtained. Since infrared rays can maintain good penetration even in bad weather such as weak light or haze weather, the weather applicable range for effective monitoring of target oil wells is improved.

[0048] Embodiment 1

[0049] In order to improve the overall oil production efficiency of oil wells while minimizing electricity costs, Figure 1 As shown, in an embodiment of the present invention, a method for remotely controlling oil well operation is provided, comprising the steps of:

[0050] S11. Generate an array C for representing the corresponding relationship between electricity price and electricity price period according to the off-peak electricity price system: C = [c1, c2, ..., c n ], where c1, c2…, c n is the electricity price in each electricity price period, and n is the number of electricity price periods;

[0051] In the embodiment of the present invention, it is assumed that the off-peak electricity price system stipulates n electricity price periods, which correspond to the corresponding electricity prices c1, c2, ..., c n .

[0052] S12. Generate an operation plan model with the goal of minimizing electricity costs:

[0053]

[0054] The constraints of the operation planning model include:

[0055] Total running time constraints: And, liquid production constraint:

[0056] Among them, x i is the target oil well in the i-th electricity price period c i The running time under is the target daily liquid production of the target oil well, is the average daily production of the past preset days; v is the target hourly liquid production, A is the unit liquid production enhancement coefficient, ranging from 1 to 1.2;

[0057] The operation planning model in the embodiment of the present invention is used to determine the operating time of the oil well in each electricity price period; by setting the total operating time constraint, it can be ensured that the full-day operating time of the target oil well will not exceed 24 hours. At the same time, the minimum liquid production constraint is also used to keep the oil production efficiency of the oil well at a high level.

[0058] In the embodiment of the present invention, the historical data of the actual liquid production of the target oil well in the previous few days is used to calculate an average value as the target production of the target oil well in the next planning period (i.e., the target daily liquid production). ); In practical applications, the setting of the preset number of days K in the embodiment of the present invention can be set by those skilled in the art based on experience or actual working conditions (such as a downward trend in oil production), and is not specifically limited here.

[0059] Calculate the average daily liquid production as the target daily liquid production The required formulas include:

[0060]

[0061] Where K represents the number of preset days. i Represents the actual liquid production on the i-th day among K days.

[0062] S13, solving the operation plan model to obtain x for each electricity price period i Generate an operation time schedule for the target oil well in the next 24 hours;

[0063] After determining the operating time of the oil well in each electricity price period, a production plan for controlling the start and stop time of the target oil well can be obtained, that is, the operating period strategy.

[0064] In actual applications, the specific content of the runtime strategy can be shown in the following table:

[0065]

[0066] S14, generating a start / stop instruction for the target oil well according to the operation period plan; sending the start / stop instruction to a near-field PLC of the target oil well; and the near-field PLC is used to execute control instructions including the start / stop instruction.

[0067] The application scenario of the embodiment of the present invention is that the remote control center generates a control instruction, sends the control instruction to the near-field PLC of the target oil well through the communication line, and performs operation control such as starting and stopping the oil pump through the near-field PLC.

[0068] From the above, it can be seen that, on the one hand, the embodiment of the present invention uses the average value of the all-day production in the past few days as a reference for the all-day liquid production of planned production (i.e., the target daily liquid production); on the other hand, a preset algorithm is used to calculate the liquid production per unit hour based on the target daily liquid production as the target hourly liquid production; in this way, after establishing an operation plan model with the goal of minimizing electricity costs, constraints based on the target hourly liquid production and the target daily liquid production can be set to obtain a combination strategy for the operating time in each electricity price period while minimizing the electricity cost for the whole day while ensuring a higher all-day liquid production; thereby, the overall oil production efficiency of the oil well is improved under the premise of minimizing electricity costs.

[0069] Furthermore, in the embodiment of the present invention, the following steps may also be included:

[0070] S15, acquiring a monitoring image of the target oil well in real time;

[0071] In practical applications, in order to ensure the effectiveness of remote control, the operating status of the pumping unit can also be monitored by remote monitoring. At this time, an image acquisition device is installed in the near field of the pumping unit to obtain real-time monitoring images of the target oil well and transmit the monitoring images to the remote control center.

[0072] S16. Determine the current operating condition of the target oil well through image recognition according to the monitoring image, wherein the current operating condition includes the start / stop state of the target oil well.

[0073] In order to avoid manual misjudgment and omission, in the embodiment of the present invention, image recognition technology is also used to identify the working status of the oil pump so as to determine whether the oil pump has executed the corresponding start and stop actions according to the control instructions.

[0074] In most cases, oil wells are set up in outdoor environments and often need to work at night or in bad weather such as fog. At this time, the monitoring image generated by the image acquisition device will be difficult to recognize. For this reason, an infrared emitting device can also be provided in the embodiment of the present invention, and then the infrared signal collected by the image acquisition device is used to identify the current working condition of the target oil well. Specifically:

[0075] The data of the monitoring image also includes an infrared signal; the infrared signal is generated by an infrared emitting device located in the near field of the target oil well; the infrared light path generated by the infrared emitting device passes through the position when the pumping unit head reaches the highest position and is emitted to the image acquisition device of the monitoring image; the infrared light generated by the infrared emitting device after the pumping unit head descends generates an infrared signal in the monitoring image;

[0076] The infrared emitting device in the embodiment of the present invention is arranged in the near field of the target oil well. On the one hand, the infrared light path generated by the infrared emitting device is emitted to the image acquisition device. At the same time, the infrared light path also passes through the position when the pumping unit head is at the highest position. That is to say, when the pumping unit head is at the highest position, the infrared light path will be blocked, and the image acquisition device will not collect infrared signals at this time; after the pumping unit head is moved downward, the infrared light path is emitted to the image acquisition device, and the image acquisition device will collect infrared signals at this time.

[0077] At this time, the specific method of determining the current working condition of the target oil well through image recognition based on the monitoring image can be: identifying the infrared signal and determining the current stroke of the pump according to the generation frequency of the infrared signal in the monitoring image, and determining the start and stop status of the target oil well according to the current stroke.

[0078] It should be noted that the image acquisition device in the embodiment of the present invention should have an infrared light acquisition function.

[0079] Furthermore, in order to improve the recognition efficiency of infrared signals and reduce the amount of computational complexity of image recognition, in an embodiment of the present invention, the infrared light path generated by the external emitting device can be set to point to a preset area of ​​the surveillance image. This can reduce the range of image recognition and it is sufficient to perform infrared signal recognition on the preset area.

[0080] It can be concluded from the above that in the embodiment of the present invention, infrared light can also be emitted to the image acquisition device by setting an infrared emitting device in the near field of the oil pump. Since the infrared light path is set at the position when the donkey head of the oil pump reaches the highest position, when the donkey head moves down, it no longer blocks the infrared light path, and the infrared light will generate an infrared signal in the image data. After a sprint cycle is completed, the donkey head will block the infrared light path again, so that a periodic infrared signal will be generated in the image data, and then the current sprint data of the oil pump can be obtained. Since infrared rays can maintain good penetration in bad weather such as weak light or foggy weather, the weather applicable range for effective monitoring of the target oil well is improved.

[0081] In practical applications, the current indicator diagram can characterize the current working efficiency of the oil pumping unit. The closer the indicator diagram is to a parallelogram, the better the working efficiency of the oil pumping unit. The algorithm for generating the indicator diagram includes the parameter of strokes. The shape of the indicator diagram can be changed by adjusting the parameter value of the strokes. For this reason, preferably, in an embodiment of the present invention, the parameter value of the stroke parameter can be modified to make the final current indicator diagram closer to a parallelogram, thereby obtaining the optimized parameter value of the strokes. Then, a corresponding stroke adjustment instruction can be generated to optimize the strokes of the oil pumping unit through the near-field PLC.

[0082] Furthermore, in order to monitor whether the stroke frequency adjustment instruction is effectively executed, in an embodiment of the present invention, the current stroke frequency of the oil pump can be obtained by identifying an infrared signal to determine whether the stroke frequency adjustment instruction is executed.

[0083] From the above, it can be concluded that in an embodiment of the present invention, it is also possible to make the reference dynamometer diagram closer to a parallelogram by adjusting the stroke parameters used to generate the dynamometer diagram, thereby obtaining an optimized number of strokes; in this way, the strokes of the target oil well can be adjusted through the optimization results to further improve the oil production efficiency of the target oil well.
