Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0051] Those skilled in the art can understand that Figure 1 the structure shown in

[0052] As Figure 1 shown, the memory 1005 regarded as a computer storage medium may include an operating system, a network communication module, a user interface module, and an oilfield power supply program.

[0054] It should be noted that currently, when powering loads in an oilfield (such as pumping units, oil storage tanks, etc.), power supply can generally be provided from the mains power end or the renewable energy end (such as wind energy, photovoltaic energy, etc.).

[0055] However, if all power supply is from the renewable energy end, there may be a situation where the electrical energy generated by the renewable energy end is insufficient, affecting production capacity. If all power supply is from the mains power end, it may lead to a low utilization efficiency of the electrical energy generated by the renewable energy end, resulting in waste of resources. Therefore, how to select a suitable power supply end from them is an urgent problem to be solved.

[0056] To solve the above defects, this embodiment provides an oilfield power supply method. The total power demand of the oilfield to be powered can be determined according to the historical work plan of the oilfield to be powered, and then the comprehensive power generation of the renewable energy power supply end can be determined according to the power generation parameters of the renewable energy power supply end. The total power demand and the comprehensive power generation of the renewable energy are compared, and the target power supply end is selected for power supply according to the comparison result. Therefore, this embodiment can select a more suitable power supply end from the mains power end and the renewable energy power supply end as the target power supply end to power the oilfield to be powered, improving the user experience.

[0057] For the convenience of understanding, the following combines Figures 2 to 5 to specifically introduce the oilfield power supply method provided in the embodiment of the present application.

[0058] Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of the oilfield power supply method of the present invention, and the first embodiment of the oilfield power supply method of the present invention is proposed.

[0059] As Figure 2 shown, in this embodiment, the above-mentioned oilfield power supply method includes the following steps:

[0060] Step S10: Obtain the historical work plan of the oilfield to be powered, and determine the total power demand of the oilfield to be powered according to the historical work plan.

[0061] It should be noted that the method of this embodiment can be applied to the scenario of powering an oilfield. Of course, it can also be applied to other scenarios that require power supply. This embodiment does not limit this. The execution subject of the method of this embodiment can be a device with functions of oilfield power supply, network communication, and program operation, such as an oilfield power supply device, etc., or other electronic devices that implement the same or similar functions. The following uses the above-mentioned oilfield power supply device (abbreviated as device) to illustrate this embodiment and the following embodiments.

[0062] It is understandable that multiple power supply required areas can be divided in the above-mentioned oilfield to be powered, and corresponding pumping units and oil storage tanks can be set in each power supply required area. The number of specific power supply required areas and the number of pumping units and oil storage tanks in each power supply required area are not limited in this embodiment.

[0063] It should be understood that the historical work plan of the above-mentioned oilfield to be powered can be the work plan of the oilfield to be powered in each historical time period, where the historical time period can be set according to the actual situation. In this embodiment, 24 hours (i.e., one day) is used for illustration, but it is not limited thereto.

[0064] The above-mentioned historical work plan can be the work plan of the pumping units and oil storage tanks in each power supply required area within every 24 hours in the past, which can include the rated power, the oil pumping volume per unit time, and the power consumption for oil pumping of the pumping unit within every 24 hours in the past, and can also include the power consumption per unit time during heating and the power consumption per unit time during constant temperature of the oil storage tank within every 24 hours in the past. This embodiment is not limited thereto specifically.

[0065] The total power demand mentioned above can be the power consumption of the above-mentioned oilfield to be powered within a preset time period in the future. The preset time period in the future can be set according to the actual situation. In this embodiment, 24 hours is used for illustration; that is, after obtaining the historical work plan, the above-mentioned device can determine the actual power consumption of the oilfield to be powered within the previous 24 hours according to the historical work plan, and then determine the total power demand of the oilfield to be powered within the next 24 hours according to the actual power consumption.

[0066] Step S20: Obtain the power generation parameters of the renewable energy power supply end, and predict the comprehensive renewable energy power generation of the renewable energy power supply end based on the power generation parameters.

[0067] It should also be noted that the above-mentioned renewable energy power supply end can be a power supply end that uses renewable energy such as wind power / solar power for power generation. The power generation parameters of the above-mentioned renewable energy power supply end can be the relevant parameters for power generation of the renewable energy power supply end within the next 24 hours, such as the wind level within the next 24 hours and the solar illumination intensity within the next 24 hours. This embodiment is not limited thereto specifically.

[0068] After the above-mentioned device determines the power generation parameters, it can predict how much power the renewable energy power supply end can generate within the next 24 hours based on the power generation parameters, which is used as the above-mentioned comprehensive renewable energy power generation.

[0069] Step S30: Compare the total power demand with the comprehensive renewable energy power generation.

[0070] Step S40: Select a target power supply terminal to supply power to the oil field to be powered according to the comparison result. The target power supply terminal includes at least one of the renewable energy power supply terminal and the mains power supply terminal.

[0071] In a specific implementation, after the above device determines the total power demand of the oil field to be powered and the comprehensive power generation of the renewable energy power supply terminal within the next 24 hours, it can compare the total power demand with the comprehensive power generation of the renewable energy, and select the mains power supply terminal or the renewable energy power supply terminal as the target power supply terminal to supply power to the oil field to be powered according to the comparison result. It can also use the mains power supply terminal and the renewable energy power supply terminal together as the target power supply terminal to supply power to the oil field to be powered.

[0072] Furthermore, in order to accurately select the target power supply terminal, in this embodiment, the step of selecting the target power supply terminal to supply power to the oil field to be powered according to the comparison result includes:

[0073] Step S41: When the total power demand is higher than the comprehensive power generation of the renewable energy, use the renewable energy power supply terminal and the mains power supply terminal as the target power supply terminals to supply power to the oil field to be powered.

[0074] It should be noted that when the total power demand is higher than the comprehensive power generation of the renewable energy, it means that the power generation of the renewable energy power supply terminal within the next 24 hours cannot meet the power consumption required by the oil field to be powered within the next 24 hours. Therefore, the above device can supply power to the oil field to be powered through the renewable energy power supply terminal and the mains power supply terminal together within the next 24 hours, that is, adopt a parallel power supply method with multiple power generation terminals, and first use the renewable energy power supply terminal for power supply. When the renewable energy power supply terminal is insufficient, the mains power supply terminal is used for supplementation.

[0075] It should be emphasized that in this embodiment, the bus direct connection technology can be adopted to directly combine the renewable energy power supply terminal with the oil field to be powered, without the need for an inverter and grid connection links, and directly supply power to the oil field to be powered through the DC bus, thereby reducing the unit cost and improving the efficiency.

[0076] Step S42: When the total power demand is not higher than the comprehensive power generation of the renewable energy, use the renewable energy power supply terminal as the target power supply terminal to supply power to the oil field to be powered.

[0077] It can be understood that when the total power demand is not higher than the comprehensive power generation of the renewable energy, it means that the power generation of the renewable energy power supply terminal within the next 24 hours can meet the power consumption required by the oil field to be powered within the next 24 hours. Therefore, the above device can supply power to the oil field to be powered only through the renewable energy power supply terminal within the next 24 hours, which can save the grid utilization rate and reduce resource waste.

[0078] It should also be emphasized that since this embodiment can determine the power supply method within a future preset time period according to the historical time period, that is, it can determine the power supply method for the current 24 hours according to the previous 24 hours, and then determine the power supply method for the next 24 hours according to the current 24 hours, the power supply method can be optimized and adjusted in real time, making the power supply method more flexible.

[0079] This embodiment determines the total power demand of the oil field to be powered within a future preset time period according to the historical work plan of the oil field to be powered within the historical time period, and then determines the total regenerative energy power generation within the future preset time period according to the power generation parameters of the regenerative energy power supply end within the future preset time period. The total power demand and the total regenerative energy power generation are compared, and a target power supply end is selected for power supply according to the comparison result. Therefore, this embodiment can select a more appropriate power supply end from the mains power end and the regenerative energy power supply end as the target power supply end to supply power to the oil field to be powered, improving the user experience while reducing resource waste and loss.

[0080] Refer to Figure 3 , Figure 3 which is a schematic flowchart of the second embodiment of the oil field power supply method of the present invention, based on the above first embodiment.

[0081] As Figure 3 shown, considering that in the regenerative energy power supply end, generally a regenerative energy power generation end and a battery energy storage terminal are set. The regenerative energy power generation end can be the end that directly uses regenerative energy for power generation, and the battery energy storage terminal can be the end that stores the electric energy generated by the regenerative energy power generation end. Therefore, in order to select a more appropriate power supply end for power supply, in this embodiment, the regenerative energy power supply end includes: a regenerative energy power generation end and a battery pack energy storage terminal;

[0082] Correspondingly, the above step S20 includes:

[0083] Step S21: Obtain the power generation parameters of the regenerative energy power generation end, and predict the regenerative energy power generation of the regenerative energy power generation end based on the power generation parameters.

[0084] It should be noted that the above regenerative energy power generation can be the electric energy that the regenerative energy power generation end can generate within the next 24 hours. The above device can first obtain the power generation parameters of the regenerative energy power generation end, where the power generation parameters can include the light intensity and wind force level of the regenerative energy within the next 24 hours, and then predict the regenerative energy power generation according to the power generation parameters. The specific process is as follows: the above step S21 includes:

[0085] Step S211: Obtain the predicted light intensity and predicted wind force level of the regenerative energy power generation end at each preset time point.

[0086] It is understandable that the above preset time points can be various time points within the next 24 hours. The predicted light intensity can be the light intensity received by the renewable energy power generation end using photovoltaic power generation at each time point within the next 24 hours, and the predicted wind force level can be the wind force level received by the renewable energy power generation end using wind power generation at each time point within the next 24 hours. Both the above predicted light intensity and predicted wind force level can be obtained according to the corresponding power generation end. The specific obtaining method is not limited in this embodiment.

[0087] Step S212: Determine the average light intensity according to the predicted light intensity, and determine the average wind force level according to the predicted separation level.

[0088] After obtaining the predicted light intensity and predicted wind force level at each time point (such as every whole hour), the above device can determine the average light intensity and average wind force level in the next 24 hours through the method of mean calculation. For the convenience of subsequent description, the average light intensity can be denoted as λ, and the average wind force level can be denoted as

[0089] Step S213: Determine the corresponding light intensity conversion rate based on the average light intensity, and determine the corresponding wind force conversion rate based on the average wind force level.

[0090] It should be understood that since the conversion efficiency of converting light intensity into electrical energy by the renewable energy power generation end is different under different light intensities, and the conversion efficiency of converting wind energy into electrical energy by the renewable energy power generation end is different under different wind force levels, the above device can select the corresponding light intensity conversion rate at this light intensity from the database according to the average light intensity, and select the corresponding wind force conversion rate at this wind force level from the database according to the average wind force level.

[0091] The above database can store the light intensity conversion rates corresponding to each light intensity and the wind force conversion rates corresponding to each wind force level. Among them, the light intensity conversion rate can be obtained by dividing the solar radiation amount at this light intensity by the power generation amount by the photovoltaic power generation end in each historical time period, and the wind force conversion rate can be obtained by dividing the wind energy density at this wind force level by the power generation amount by the wind power generation end in each historical time period. Of course, it can also be other methods, which are not limited in this embodiment.

[0092] Step S214: Predict the renewable energy power generation amount of the renewable energy power generation end according to the average light intensity, the light intensity conversion rate, the average wind force level, and the wind force conversion rate.

[0093] For the convenience of subsequent description, in this embodiment, the above light intensity conversion rate can be denoted as δ1, the wind force conversion rate can be denoted as δ2. If the renewable energy power generation amount is denoted as Q, and the future preset time period is denoted as T, then

[0094] Further, considering that there will be some errors in the calculation process, if the allowable error value of the renewable energy power generation of the renewable energy power generation end in this embodiment is denoted as l, then *T + l, where the specific l can be set according to the actual situation.

[0095] Step S22: Obtain the renewable energy storage amount of the battery pack energy storage terminal, and determine the comprehensive renewable energy power generation according to the renewable energy power generation and the renewable energy storage amount.

[0096] After determining the renewable energy power generation of the renewable energy power supply end, the above device can directly obtain the power stored within the past 24 hours from the battery pack energy storage terminal, and directly use it as the renewable energy storage amount of the battery pack energy storage terminal within the next 24 hours. The above renewable energy storage amount can be the power stored by the battery pack energy storage terminal within a future preset time period, that is, the power stored within the past 24 hours; and take the sum of the renewable energy power generation and the renewable energy storage amount as the comprehensive renewable energy power generation within the next 24 hours.

[0097] Since the renewable energy power supply end can include: the renewable energy power generation end and the battery pack energy storage terminal, in order to further optimize the power supply method, in this embodiment, the step of using the renewable energy power supply end as the target power supply end to supply power to the oil field to be powered includes:

[0098] Step S421: When the total power demand is not higher than the renewable energy power generation, use the renewable energy power generation end as the target power supply end to supply power to the oil field to be powered;

[0099] Step S422: When the total power demand is higher than the renewable energy power generation, use the renewable energy power generation end and the battery pack energy storage terminal as the target power supply end to supply power to the oil field to be powered.

[0100] In specific implementation, when the total power demand within the next 24 hours is not higher than the renewable energy power generation, it means that the power generated by the renewable energy power supply end is sufficient for the oil field to be powered, and thus the renewable energy power generation end can be directly used as the target power supply end to supply power to the oil field to be powered;

[0101] When the total power demand within the next 24 hours is higher than the renewable energy power generation, it means that the power generated by the renewable energy power supply end is not sufficient for the oil field to be powered, but the sum of the power of the renewable energy power supply end and the battery pack energy storage terminal is sufficient for the oil field to be powered. Therefore, the renewable energy power supply end and the battery pack energy storage terminal can be used together as the target power supply end to supply power to the oil field to be powered.

[0102] It should be emphasized that since this embodiment can supply power to the oilfield to be powered by means of multiple power supply terminals in parallel, which can include directly using a renewable energy power generation terminal, a battery energy storage terminal, and a commercial power terminal alone or in combination to supply power to the oilfield to be powered, the utilization rate of the power grid can be saved, and resource waste and loss can be reduced. At the same time, the battery energy storage terminal can efficiently store and utilize the renewable energy power generation terminal, which helps to promote the development and application of renewable energy.

[0103] At the same time, since this embodiment can predict the total power demand of the oilfield to be powered within a preset future time period and the comprehensive power generation of the renewable energy power supply terminal, and adjust it in real time according to the changing power demand at a certain time interval, the accuracy of power supply distribution is improved, and at the same time, the response speed of power supply distribution is enhanced, realizing the intelligence and automation of power quantity distribution and management, and further saving labor costs.

[0104] Referring to Figure 4 , Figure 4 is a schematic flowchart of the third embodiment of the oilfield power supply method of the present invention, based on the above embodiments.

[0105] As Figure 4 shown, in order to accurately determine the total power demand, in this embodiment, the step of determining the total power demand of the oilfield to be powered according to the historical work plan includes:

[0106] Step S11: Determine the total expected power consumption of the oilfield to be powered under the preset work plan according to the historical work plan.

[0107] It should be noted that the above preset work plan can be the work plans of each pumping unit and storage tank in the oilfield to be powered within a preset future time period, and the above total expected power consumption can be the power that the oilfield to be powered is expected to consume within the preset future time period.

[0108] The above equipment can determine the total expected power consumption of the oilfield to be powered within a preset future time period according to the historical work plan. Since the total expected power consumption can include the power consumption of the pumping unit and the power consumption of the storage tank, in this embodiment, in order to accurately determine the total expected power consumption, the above step S11 includes:

[0109] Step S111: Determine the rated power, oil pumping volume per unit time, and expected oil pumping volume of each pumping unit in the oilfield to be powered under the preset work plan according to the historical work plan.

[0110] It is understandable that the above-mentioned expected oil extraction volume can be the expected oil volume to be extracted by the pumping unit within a preset future time period. Since different expected oil extraction volumes require different times, the oil extraction volume per unit time and the rated power corresponding to the pumping unit are different under the same time cycle. Therefore, the above device can determine the oil extraction volume per unit time at different rated powers according to the historical work plan, and then determine the rated power and the oil extraction volume per unit time in the future preset time cycle according to the expected oil extraction volume set by the user.

[0111] Step S112: Determine the constant temperature power consumption and heating power consumption of each storage tank in the oil field to be powered under the preset work plan based on the historical work plan.

[0112] It should be understood that since the storage tank can heat or keep the extracted crude oil at a constant temperature, and the heating and constant temperature times required for crude oil with different material properties are inconsistent, the above device can calculate the expected heating duration and expected constant temperature duration required for different amounts of crude oil with different material properties within the historical time cycle according to the historical work plan, and determine the power consumption during the expected heating duration and the power consumption during the expected constant temperature duration, and then determine the heating power consumption per unit time and the constant temperature power consumption per unit time required for the storage tank to store the crude oil of this quantity and this material, and then determine the power consumption required for the storage tank to keep at a constant temperature (i.e., the above constant temperature power consumption) and the power consumption required for heating (i.e., the above heating power consumption) under the preset work plan.

[0113] Step S113: Determine the first expected power consumption corresponding to each pumping unit through each of the rated powers, each of the oil extraction volumes per unit time, and each of the expected oil extraction volumes.

[0114] After determining the rated power, the oil extraction volume per unit time, and the expected oil extraction volume of each pumping unit, the above device can calculate the power consumption of the pumping unit within the future preset time cycle as the above first expected power consumption.

[0115] It should be emphasized that since the pumping unit may be affected by factors such as aging and rusting with the increase of the total oil volume already extracted, the above device can also store the mechanical loss influence factors of each pumping unit at the current total oil volume already extracted to represent the influence brought by aging and rusting.

[0116] At the same time, since the number and location of the pumping units in different areas to be powered in the oil field to be powered are different, the above device can also obtain the layout information of the oil field to be powered, where the layout information can include the number and distribution locations of the pumping units in each area to be powered, and determine the DC bus power supply length between each pumping unit and the renewable energy power supply end and the oil pipe connection length between each pumping unit and the storage tank according to the layout information.

[0117] Furthermore, the above device can determine the first estimated power consumption of each pumping unit in combination with the mechanical loss impact factor and the tubing connection length.

[0118] Step S114: Determine the second estimated power consumption corresponding to each storage tank according to each of the constant temperature power consumption and each of the heating power consumption.

[0119] In a specific implementation, the above device can determine the power consumption of the storage tank within a future preset time period based on the sum of the constant temperature power consumption and the heating power consumption of the obtained storage tank, and use it as the above second estimated power consumption.

[0120] Step S115: Determine the total estimated power consumption based on each of the first estimated power consumption and each of the second estimated power consumption.

[0121] In a specific implementation, the above device can use the sum of the first estimated power consumption of each pumping unit under the preset work plan and the sum of the second estimated power consumption of each storage tank under the preset work plan as the total estimated power consumption of the oil field to be powered under the expected work plan.

[0122] Step S12: Obtain the energy loss impact index of the oil field to be powered, and determine the total power demand of the oil field to be powered based on the energy loss impact index and the total estimated power consumption.

[0123] It should be noted that since there may be losses during the transmission of electric energy, the above device can determine the power generated by the renewable energy power supply end and the power provided by the renewable energy power supply end received by the oil field to be powered during the historical time period according to the historical work plan, and then determine the energy loss impact index of the oil field to be powered. Then, based on the total estimated power consumption of the oil field to be powered under the expected work plan and the energy loss impact index, the total power demand is determined, thereby improving the accuracy of the determination.

[0124] Furthermore, in order to reflect the energy utilization rate of each pumping unit and each storage tank in real time, so that users can understand the situation in time and make adjustments, in this embodiment, the above device can also obtain the actual power consumption of the pumping unit under the preset work plan and the above first estimated power consumption, and divide the actual power consumption of the pumping unit by the first estimated power consumption and multiply by 100% to obtain the energy utilization rate of the pumping unit;

[0125] Similarly, the above device can obtain the actual power consumption of the storage tank and the second estimated power consumption under the preset work plan, and divide the actual power consumption of the storage tank by the second estimated power consumption and multiply by 100% to obtain the energy utilization rate of the storage tank.

[0126] After determining the energy utilization rate of the pumping unit and the energy utilization rate of the storage tank, the above-mentioned equipment can monitor the energy utilization rate in real time. When the energy utilization rate of a certain pumping unit is lower than the average energy utilization rate of all pumping units, the above-mentioned equipment can give an early warning. Similarly, when the energy utilization rate of a certain storage tank is lower than the average energy utilization rate of all storage tanks, the above-mentioned equipment can also give an early warning to prompt the user to make relevant adjustments in a timely manner.

[0127] Therefore, since this embodiment can monitor the energy utilization rate of the pumping unit and the storage tank in real time, promptly discover the situations of energy waste and inefficient use, and thus helps to improve the energy utilization efficiency, indirectly avoiding potential dangerous problems of power supply.

[0128] In addition, an embodiment of the present invention also proposes a storage medium, on which an oilfield power supply program is stored. When the oilfield power supply program is executed by a processor, it realizes the oilfield power supply method as described above.

[0129] In addition, referring to Figure 5 , Figure 5 is the structural block diagram of the first embodiment of the oilfield power supply device of the present invention; an embodiment of the present invention also proposes an oilfield power supply device, which includes: a plan acquisition module 501, a parameter acquisition module 502, a power quantity comparison module 503, and a power supply selection module 504;

The total power demand and the total regenerative energy power generation are compared, and the target power supply end is selected for power supply according to the comparison result. Therefore, in this embodiment, a more suitable power supply end can be selected from the mains power supply end and the regenerative energy power supply end as the target power supply end to supply power to the oilfield to be powered, improving the user experience while reducing resource waste and loss.

[0135] As an implementation manner, the power supply selection module 504 is further configured to, when the total power demand is higher than the total regenerative energy power generation, use the regenerative energy power supply end and the mains power supply end as the target power supply end to supply power to the oilfield to be powered; when the total power demand is not higher than the total regenerative energy power generation, use the regenerative energy power supply end as the target power supply end to supply power to the oilfield to be powered.
