Description

Technical Field

[0001] The present invention relates to the field of oil well exploitation, and in particular to a storage medium, a method, a device and equipment for generating an oil well operation plan. 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:

[0046] Embodiment 1

[0047] 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 generating an oil well operation plan is provided, comprising the steps of:

[0048] S11, obtaining multiple dynamometer diagrams of the target oil well within 24 hours of retrospection, and generating a reference dynamometer diagram for representing the optimal liquid production according to the multiple dynamometer diagrams;

[0049] In practical applications, 48 ​​dynamometer diagrams may be generated every day (24 hours) at a cycle of generating one dynamometer diagram every half hour, that is, the dynamometer transmits the dynamometer diagram data once every half hour.

[0050] With 24 hours as a planning cycle, a time point is set for making a plan; with this time point as the starting point, go back 24 hours (one day) to obtain 48 dynamometer diagrams generated during this period.

[0051] The closer the dynamometer diagram is to a parallelogram, the better its liquid production efficiency is. Therefore, the dynamometer diagram closest to a parallelogram can be selected from multiple dynamometer diagrams as a reference dynamometer diagram.

[0052] S12, calculating the optimal liquid production V of the target oil well according to the reference work diagram opt ; and calculate the theoretical optimal hourly liquid production V per ;

[0053] According to the parameters corresponding to the reference dynamometer diagram, such as effective stroke, stroke frequency and pump displacement coefficient, the theoretical maximum liquid production for 24 hours can be calculated (i.e., the optimal liquid production V opt ), the specific calculation formula can be as follows:

[0054] V opt =S e ×N j ×α p ;

[0055] Among them, V opt To trace back the optimal liquid production, S e is the effective stroke, N j is the number of strokes, α p is the pump displacement coefficient.

[0056] The theoretically optimal hourly liquid production V per , the required formulas include:

[0057] V per =V opt / twenty four.

[0058] S13. Calculate the average daily liquid production as the target daily liquid production based on the historical daily liquid production of the preset number of days.

[0059] Using the historical data of the actual liquid production of the target well in the previous few days, an average value can be calculated

[0060] as the target production of the target oil well in the next planning period (i.e., 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.

[0061] Calculate the average daily liquid production as the target daily liquid production The required formulas include:

[0062]

[0063] Where K represents the number of preset days. i Represents the actual liquid production on the i-th day among K days.

[0064] S14. 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;

[0065] 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 .

[0066] S15. Generate an operation plan model with the goal of minimizing electricity costs:

[0067]

[0068] The constraints of the operation planning model include:

[0069] Total running time constraints: And, minimum liquid production constraint:

[0070] Among them, x i is the i-th electricity price period c i The running time under V per is the liquid production per hour; The target daily liquid production.

[0071] 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.

[0072] Furthermore, the present invention may further include the steps of:

[0073] S16, solving the operation plan model to obtain x for each electricity price period i Generate an operation time period strategy for the target oil well in the next 24 hours.

[0074] 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.

[0075] In actual applications, the specific content of the runtime strategy can be shown in the following table:

[0076]

[0077] In practical applications, the dynamometer diagram closest to a parallelogram selected from multiple dynamometer diagrams may not necessarily be in the best working condition. For example, the stroke setting of the target oil well may not be the best choice. In other words, the dynamometer diagram closest to a parallelogram selected at this time cannot fully represent the liquid production efficiency of the target oil well.

[0078] The algorithm for generating the dynamometer diagram includes the parameter of stroke frequency. The shape of the dynamometer diagram can be changed by adjusting the parameter value of the stroke frequency. For this reason, preferably, in the embodiment of the present invention, the parameter value of the stroke frequency parameter can be modified to make the final reference dynamometer diagram closer to a parallelogram, thereby obtaining the optimized parameter value of the stroke frequency. In this way, on the one hand, the theoretical optimal hourly liquid production obtained by subsequent calculation can be closer to the theoretical maximum liquid production, so that the operation plan model in the embodiment of the present invention can further tap the production potential of the oil well;

[0079] On the other hand, the subsequent production of the oil well can be more efficient. That is to say, by setting the optimized flushing frequency for the next planned cycle (i.e. the next 24 hours) of the target oil well, the production efficiency of the oil well can be further improved.

[0080] In summary, the embodiment of the present invention, on the one hand, takes the most efficient dynamometer diagram of multiple dynamometer diagrams of the day that have passed as the basis, calculates the theoretical optimal unit hourly liquid production as the unit hourly liquid production for planned production (i.e., the theoretical optimal hourly liquid production); on the other hand, it also takes the average value of the full-day production in the past few days as the full-day liquid production reference for planned production (i.e., the target daily liquid production); in this way, after establishing an operation plan model with the goal of minimizing electricity costs, constraints based on the theoretical optimal 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 electricity cost for the whole day while ensuring a higher full-day liquid production; thereby achieving the improvement of the overall oil production efficiency of the oil well under the premise of minimizing electricity costs.

[0081] Furthermore, 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, on the one hand, the theoretical optimal hourly liquid production that is more suitable for the current operating conditions of the target oil well can be calculated; on the other hand, 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.
