DETAILED DESCRIPTION

[0015] like Figure 1As shown, an embodiment of the present invention provides a method for intelligent inter-pumping control of oil and gas fields based on the Hongmeng system. The method can be but is not limited to being applied to an inter-pumping intelligent control platform built on the Hongmeng system. The oil and gas fields are equipped with corresponding oil pumps, and the inter-pumping intelligent control platform is connected to the oil pumps. Specifically, it can include but is not limited to steps S1 to S5; wherein, the inter-pumping intelligent control platform can be but is not limited to being built based on the nationally produced open source Hongmeng system. For example, the hardware architecture and software architecture associated with the inter-pumping intelligent control platform can be built based on the microkernel of the open source Hongmeng system. The real-time operation data of the oil pumps can be analyzed, calculated and converted through the efficient computing environment and stable data logic framework provided by the open source Hongmeng system, thereby achieving the technical purpose of improving the inter-pumping efficiency of the oil pumps.

[0016] Step S1, controlling the oil pump to maintain operation for a first preset time, and after the operation is completed, stopping the oil pump for a second preset time, and controlling the oil pump to maintain operation for a third preset time; It can be understood that the specific values ​​of the first preset time, the second preset time and the third preset time can be set by technicians in this field according to experience, production requirements and other factors. However, no matter how they are set, the intelligent intermittent extraction control method in this embodiment can be applied. In other words, the settings of the first preset time, the second preset time and the third preset time in step S1 are not uniquely limited. For example, in some application scenarios, step S1 can be executed multiple times, but is not limited to, and the first preset time, the second preset time and the third preset time used in each execution of step S1 may not be completely the same. Such trial operation data will be richer, which is beneficial to the calculation in subsequent steps. However, this is not a limitation, and technicians in this field can choose to execute according to the actual scenario. Step S2, respectively obtaining the corresponding pumping load parameters, liquid production and oil water content of the pumping unit in the first preset time and the third preset time, calculating the load difference between the pumping load parameter corresponding to the first preset time and the pumping load parameter corresponding to the third preset time, judging whether the first operating condition and the second operating condition are met at the same time, if so, determining the target startup time according to the first preset time and the third preset time, taking the second preset time as the target shutdown time, and executing step S4, otherwise executing step S3; The first operating condition is that the load difference is within a preset difference threshold range, and the second operating condition is that the oil water content corresponding to the first preset time and the oil water content corresponding to the third preset time are both less than or equal to the preset oil water content threshold, or at least one of the liquid production corresponding to the first preset time and the liquid production corresponding to the third preset time is greater than or equal to the preset liquid production threshold; The pumping load parameter reflects the maximum force or torque that the pumping unit needs to bear during operation, and can be used as a relevant operating parameter to measure the real-time working efficiency of the pumping unit; the liquid production volume represents the real-time liquid production of the oil well, and the water content of the oil production represents the purity of the oil products collected in real time from the oil well; Step S3, taking the pumping load parameters, liquid production and oil water content corresponding to the first preset duration and the third preset duration respectively as input data, and inputting them into the duration estimation model based on the Hongmeng system for training, so as to obtain a pre-trained duration estimation model; when the current pumping load parameters, current liquid production and current oil water content of the oil pumping unit are determined, the current pumping load parameters, current liquid production and current oil water content are input into the pre-trained duration estimation model, so as to obtain the target startup duration, and determine the target shutdown duration according to the first preset duration, the second preset duration and the third preset duration; It should be noted that there can be multiple specific types of duration estimation models based on the Hongmeng system. Technical personnel in this field can select the corresponding duration estimation model according to the actual application scenario, such as selecting the convolutional neural network, residual neural network, etc. configured accordingly under the Hongmeng system architecture, which is not limited here; there is no specific restriction on the method of training the duration estimation model, for example, it can be but not limited to: first, the oil pumping load parameters, liquid production and oil water content corresponding to the first preset time length and the third preset time length are normalized, and then all the normalized data are used as input data, and the input data is trained. Input to the input layer of the duration estimation model, and finally output the trained startup duration, etc. through the output layer of the duration estimation model; wherein, the input data can also be but not limited to more types, for example, as mentioned in the aforementioned embodiment, step S1 can be performed multiple times, then correspondingly, through step S2, multiple groups of preset durations and their corresponding pumping load parameters, liquid production and oil water content can be obtained, that is, in this case, more input data are obtained, but this is not the only limitation, and those skilled in the art can select relevant data for training the duration estimation model according to actual scenarios, application requirements, etc., which is not limited here; Step S4, determining the intermittent pumping working cycle of the oil pumping unit according to the target startup time and the target shutdown time, controlling the oil pumping unit to work according to the intermittent pumping working cycle, and obtaining the fullness of the oil pumping unit at a preset sampling time within the intermittent pumping working cycle, and judging whether the fullness is lower than the minimum fullness threshold, if so, controlling the oil pumping unit to stop working, otherwise executing step S5, that is, if the fullness is lower than the minimum fullness threshold, it means that the fullness does not meet the minimum requirement, and accordingly, the pumping efficiency cannot reach the expected level, so the oil pumping unit is controlled to stop working to reduce unnecessary energy loss; It should be noted that the preset sampling moment can be selected and set according to the actual situation, and can be set to multiple. When it is set to multiple, the fullness obtained at each preset sampling moment can be judged one by one, and the judgment condition can be set accordingly. For example, in one case, strict judgment is performed, and all fullnesses are required to be lower than the minimum fullness threshold before the oil pump is controlled to stop working. Or, in another case, non-strict judgment is performed, and the oil pump is controlled to stop working only if the number of fullnesses of all fullnesses lower than the minimum fullness threshold is less than the preset proportion, etc. There is no limitation here; There may be more types of fullness that are selected, which are not limited here. For example, considering the energy consumption balance of the oil pump, the fullness corresponding to the energy consumption balance condition may be selected.

[0017] Step S5, continuously obtaining the pumping operation parameters of the oil pumping unit in the intermittent pumping working cycle, and determining the corresponding relationship between the power parameter and the fullness in the intermittent pumping working cycle according to the pumping operation parameters in the intermittent pumping working cycle; Among them, the method of determining the intermittent pumping working cycle of the oil pumping unit can be, but is not limited to, set accordingly according to the actual application scenario. Generally speaking, the intermittent pumping working cycle should at least include a target startup time and a target shutdown time. The target startup time and the target shutdown time can be continuous or non-continuous. For example, other required times such as oil pumping unit equipment maintenance time and running standby time are inserted into the intermittent pumping working cycle. Obviously, after these other required times are added, the intermittent pumping working cycle will not only include the target startup time and the target shutdown time. Of course, under ideal circumstances, the intermittent pumping working cycle only includes the target startup time and the target shutdown time. Continuously obtain the pumping The specific method of obtaining the oil pumping operation parameters can be set accordingly according to actual needs. For example, the oil pumping operation parameters can be obtained according to a preset time interval. Different time intervals form different sampling moments in the intermittent pumping work cycle. The oil pumping operation parameters are obtained at each sampling moment. Specifically, if it is assumed that the intermittent pumping work cycle is from 14:00 to 22:00, and every 2 hours is taken as an equal time interval, then 4 corresponding sampling moments can be obtained between 14:00 and 22:00, and the oil pumping operation parameters are obtained and recorded at these 4 sampling moments respectively, or the oil pumping operation parameters can be obtained by random sampling, etc., which is not limited here; Step S6: Determine the target power parameter of the oil pumping unit according to the preset power operating conditions and the corresponding relationship between the power parameter and the fullness within the intermittent pumping working cycle.

[0018] In this step, an inter-pumping intelligent control platform is constructed based on the Hongmeng system, which provides a flexible and scalable system architecture, and then the intelligent inter-pumping control of the oil pumping unit is realized through the inter-pumping intelligent control platform as a whole. Specifically, the oil pumping unit is controlled to enter the trial operation state with the first preset time, the second preset time and the third preset time, and then the effectiveness of the pumping load parameters, liquid production and oil water content in the trial operation state is judged, so as to determine the target startup time and target shutdown time according to the judgment result, and the target startup time and target shutdown time constitute the inter-pumping working cycle of the oil pump, so as to The pumping duty cycle controls the operation of the oil pumping unit. It can be seen that, based on the monitoring of the oil well production conditions, the influence of the actual operation conditions of the oil pumping unit is further considered, and debugging calculations are performed based on the obtained trial operation parameters of the oil pumping unit. Therefore, a reasonable and reliable intermittent pumping duty cycle can be determined to improve the intermittent pumping efficiency of the oil pumping unit. Moreover, in the process of the oil pumping unit operating with the intermittent pumping duty cycle, the fullness and pumping operation parameters of the oil pumping unit are monitored in real time to adjust the real-time power state of the oil pumping unit, to ensure that the oil pumping unit maintains a good working state during the intermittent pumping duty cycle, to further improve the intermittent pumping efficiency of the oil pumping unit.

[0019] It should be noted that the specific composition architecture, parameters, etc. of the intelligent control platform are not restricted, and can be but not limited to being set up by technical personnel in this field according to actual application scenarios. Since the domestically produced Hongmeng system belongs to the relevant existing technology in this field, it will not be elaborated here to avoid redundancy.

[0020] In one embodiment of the present invention, the steps in step S2, determining the target power-on duration according to the first preset duration and the third preset duration, may include but are not limited to the following steps: Step S21: Substitute the first preset duration and the third preset duration into the duration estimation calculation formula to calculate and obtain the target power-on duration, wherein the duration estimation calculation formula is as follows: ; The target boot time is is the first preset duration, For the third preset duration, is the preset duration compensation coefficient, .

[0021] In this step, by judging whether the first operating condition and the second operating condition are met at the same time, it means that the first preset duration and the third preset duration are valid data under the intermittent operation condition. Therefore, the required power-on duration can be further determined based on the first preset duration and the third preset duration, and the first preset duration and the third preset duration are substituted into the duration estimation calculation formula for calculation to obtain the target power-on duration, wherein the preset duration compensation coefficient represents the error influence of the first preset duration and the third preset duration when performing duration estimation.

[0022] It should be noted that , The specific size relationship of can be configured according to the specific situation of different scenarios, depending on the emphasis of the spacing method. There is no restriction here. For example, to analyze the possible level of impact of the initial operation of the pumping unit, then Set larger, accordingly, On the contrary, if the goal is to analyze the possible level of impact on the subsequent operation of the pumping unit, then Set smaller, accordingly, Set it bigger.

[0023] like Figure 2 As shown, in one embodiment of the present invention, the steps in step S3, determining the target downtime duration according to the first preset duration, the second preset duration and the third preset duration, may include but are not limited to the following steps: Step S31, obtaining a duration difference between the first preset duration and the third preset duration; Step S32: when the second preset duration meets the duration determination condition, the second preset duration is used as the target downtime duration; or, when the second preset duration does not meet the duration determination condition, the duration difference is used as the target downtime duration, wherein the duration determination condition is that the second preset duration is less than or equal to the duration difference, and is less than the first preset duration or the third preset duration.

[0024] In this step, the duration difference between the first preset duration and the third preset duration is calculated to further determine whether the second preset duration meets the duration determination condition. Since the duration determination condition is that the second preset duration is less than or equal to the duration difference and less than the first preset duration or the third preset duration, that is to say, the second preset duration needs to simultaneously meet the condition of being less than or equal to the duration difference and less than any one of the preset durations before the second preset duration can be considered to meet the current duration requirement, thereby taking the second preset duration as the target downtime duration, otherwise taking the duration difference as the target downtime duration, and the duration difference meets the current duration requirement. It can be seen that by determining whether the second preset duration meets the duration determination condition, an accurate and reliable target downtime duration can be determined accordingly.

[0025] like Figure 3 As shown, in one embodiment of the present invention, when the pumping operation parameters include pumping speed parameters, operating temperature parameters and oil well pressure parameters, the steps in step S5, determining the corresponding relationship between the power parameter and the fullness within the intermittent pumping working cycle according to the pumping operation parameters within the intermittent pumping working cycle, may include but are not limited to the following steps: Step S51, for the obtained pumping operation parameters at any time during the intermittent pumping working cycle, determine whether the pumping operation parameters meet the ideal pumping operation conditions, if so, retain the pumping operation parameters at this time, otherwise filter out the pumping operation parameters at this time, wherein the ideal pumping operation conditions are that the pumping speed parameter is not lower than the minimum preset speed threshold, the operating temperature parameter does not exceed the maximum preset temperature threshold, and the oil well pressure parameter is within the preset flow pressure threshold range; Step S52, respectively calculating the mean of all the retained pumping speed parameters, operating temperature parameters and oil well pressure parameters, so as to obtain a comprehensive pumping speed parameter, a comprehensive operating temperature parameter and a comprehensive oil well pressure parameter; Step S53, determining the corresponding relationship between the power parameter and the fullness within the intermittent pumping working cycle according to the comprehensive pumping speed parameter, the comprehensive operating temperature parameter and the comprehensive oil well pressure parameter.

[0026] In this step, by judging whether the pumping operation parameters at any moment meet the ideal pumping operation conditions, all the pumping operation parameters that meet the ideal pumping operation conditions are found. This part of the pumping operation parameters corresponds to the ideal working state of the pumping unit. Then, all the retained pumping speed parameters, operating temperature parameters and oil well pressure parameters are averaged to obtain comprehensive pumping speed parameters, comprehensive operating temperature parameters and comprehensive oil well pressure parameters. The corresponding relationship between the power parameters and the fullness of the pumping unit during the intermittent pumping working cycle can be effectively and reliably determined based on the comprehensive pumping speed parameters, comprehensive operating temperature parameters and comprehensive oil well pressure parameters.

[0027] It should be noted that the pumping operation parameters may also include but are not limited to more types of operation parameters, which are selected by technical personnel in this field according to different scenarios and are not limited here. For example, they may be well depth temperature parameters, oil well permeability parameters, etc.

[0028] In one embodiment of the present invention, step S53 may include but is not limited to the following steps: Step S531: Substitute the comprehensive pumping speed parameter, the comprehensive operating temperature parameter and the comprehensive oil well pressure parameter into the power simulation calculation formula to calculate and obtain the corresponding functional relationship between the power parameter and the fullness within the intermittent pumping working cycle, wherein the corresponding functional relationship is as follows: ; is the power parameter, is the starting time of the intermittent working cycle, is the end time of the intermittent working cycle, is any moment in the intermittent working cycle, is the comprehensive pumping speed parameter, is the comprehensive operating temperature parameter, is the comprehensive oil well pressure parameter, is the preset temperature influence factor, is the preset power compensation factor, For fullness.

[0029] In this step, the corresponding function relationship reflects the corresponding function relationship between the power parameter and the fullness, where: This integral term represents the influence of the pumping speed parameter in the entire intermittent pumping cycle. Characterize the influence of operating temperature parameters on the real-time operating status of the pumping unit, Preferably 0.5 to 0.8, Characterize the influence of oil well pressure parameters and fullness during the entire intermittent pumping cycle. Preferably it is 1.5~2.5.

[0030] like Figure 4 As shown, in one embodiment of the present invention, step S6 may include but is not limited to the following steps: Step S61, substituting the fullness into the corresponding function relationship to calculate and obtain the corresponding simulation power parameter; Step S62: adjusting the simulated power parameters according to the preset power operating conditions, and using the adjusted simulated power parameters as the target power parameters of the oil pump.

[0031] In this step, since the corresponding functional relationship between the power parameter and the fullness has been determined in the above-mentioned embodiment, when the specific value of the fullness is determined, the corresponding simulated power parameter can be calculated by substituting the formula, and then the simulated power parameter is adjusted according to the preset power operating conditions to adjust the simulated power parameter to be more in line with the ideal operating condition of the oil pump. Finally, the adjusted simulated power parameter is used as the target power parameter of the oil pump, so that the oil pump is in a good power operating state.

[0032] It should be noted that, as described in the previous embodiment, if there are multiple fullnesses at preset sampling moments that meet the threshold condition, the largest fullness may be selected as the final fullness and substituted into the corresponding function relationship for calculation, but is not limited to.

[0033] like Figure 5As shown, in one embodiment of the present invention, when the preset power operating condition includes an ideal power threshold and a maximum power threshold, and the ideal power threshold is less than the maximum power threshold, the steps in step S62, adjusting the simulated power parameters according to the preset power operating condition, may include but are not limited to the following steps: Step S621: When the analog power parameter is less than the ideal power threshold or greater than the maximum power threshold, the analog power parameter is adjusted to the ideal power threshold; or, when the analog power parameter is greater than or equal to the ideal power threshold and less than or equal to the maximum power threshold, the analog power parameter is maintained unchanged.

[0034] In this step, when the simulated power parameter is greater than or equal to the ideal power threshold and less than or equal to the maximum power threshold, it means that the simulated power parameter is within a suitable threshold range, so the current simulated power parameter can be maintained unchanged; when the simulated power parameter is less than the ideal power threshold or greater than the maximum power threshold, it means that the simulated power parameter at this time is either too small or too large and is not within a reasonable threshold range, which may affect the overall operating efficiency of the oil pump. Therefore, in this case, the simulated power parameter is adjusted to the ideal power threshold to improve the operating efficiency of the oil pump and reduce safety hazards. Among them, the specific value of the ideal power threshold is not restricted, and can be selected and set accordingly according to the actual scenario.
