Specifically, in the area suitable for building an oil and gas reservoir storage, the gas demand of local industrial users and residential users is fully investigated, a distribution network is established during the construction of the storage, and distribution users are configured.

[0047] Generally, the pressure of the downstream distribution user is about 3-5 MPa, which is much lower than the lower limit operating pressure of the storage. During the gas extraction process of the storage, when it is monitored that the pressure of the storage decreases to the pipeline network pressure, the channel between the storage and the pipeline network is cut off, the gas transmission to the natural gas pipeline network is stopped, and the gas transmission to the distribution user is changed, the residual pressure of the storage is used to continue the gas extraction, the reservoir pressure of the storage is continuously exploited to the lower limit pressure, the productivity of the storage is fully played, the utilization efficiency of the storage is improved, and as much gas as possible is extracted to improve the economic benefit of the storage.

[0048] Optionally, the distribution pressure of the distribution network is lower than the preset pipeline network pressure. The distribution pressure of the distribution network is lower than the preset pipeline network pressure, the reservoir pressure of the storage can be continuously exploited to the lower limit pressure after the pressure of the storage decreases to the pipeline network pressure, the productivity of the storage is fully played, the utilization efficiency of the storage is improved, and as much gas as possible is extracted to improve the economic benefit of the storage.

[0050] In the embodiment of the present application, in the gas extraction process of the gas storage, when it is monitored that the pressure of the gas storage decreases to the pressure of the pipe network, the channel between the gas storage and the pipe network is cut off, the gas extraction to the pipe network is stopped, the gas extraction is continued by using the residual pressure of the gas storage in the form of liquefied compressed natural gas, the reservoir pressure of the gas storage is continuously exploited to the lower limit pressure, the production capacity of the gas storage is fully utilized, the utilization efficiency of the gas storage is improved, and the economic benefit of the gas storage is improved as much as possible.

[0051] Figure 2 The oil and gas reservoir gas storage production capacity regulation system is shown in an exemplary embodiment of the present application. As shown in the figure, the oil and gas reservoir gas storage production capacity regulation system comprises a pressure monitoring module and a main control module. Figure 2 The main control module is used for cutting off the channel between the oil and gas reservoir gas storage and the pipe network when the outlet pressure of the injection-production station is lower than the preset pipe network pressure, and is also used for continuously extracting gas from the oil and gas reservoir gas storage by a preset gas extraction scheme until the gas extraction is stopped when the preset lower limit pressure is reached.

[0052] The pressure monitoring module is used for monitoring the outlet pressure of the injection-production station of the oil and gas reservoir gas storage in real time.

[0053] The main control module is used for cutting off the channel between the oil and gas reservoir gas storage and the pipe network when the outlet pressure of the injection-production station is lower than the preset pipe network pressure, and is also used for continuously extracting gas from the oil and gas reservoir gas storage by a preset gas extraction scheme until the gas extraction is stopped when the preset lower limit pressure is reached.

[0054] In the embodiment of the present application, when it is monitored that the outlet pressure of the injection-production station is lower than the preset pipe network pressure, the channel between the oil and gas reservoir gas storage and the pipe network is cut off, and the oil and gas reservoir gas storage is continuously extracted by a preset gas extraction scheme. Compared with the traditional gas extraction mode in which only gas is extracted to the pipe network and the gas extraction is stopped when the pressure is equal to the pipe network pressure, the gas extraction amount is significantly increased in the embodiment of the present application, and at the same time, the injectable gas amount in the next stage is also increased, the annual injection-production gas amount is improved. The reservoir space near the well bottom is fully flushed, the wellbore permeability is improved, the skin factor is reduced, the well bottom pollution is improved, the single well injection and production capacity is further improved, and it is beneficial to the capacity and production of the gas storage.

[0055] The embodiment of the present application can effectively increase the extracted gas amount of the gas storage, increase the gas injection amount, fully utilize the peak regulation effect of the gas storage, improve the utilization rate of the gas storage, reduce the pipe storage pressure during the gas consumption peak period, slow down the pipe network gas transmission pressure, increase the storage and transfer fee income of the gas storage, shorten the payback time of the gas storage, reduce the operation time of the gas storage branch line, and appropriately reduce the main line maintenance content according to the actual needs.

[0056] Optionally, in an exemplary embodiment, the oil and gas reservoir gas storage production capacity regulation system further comprises a pre-established distribution network; the pre-established distribution network is used for transporting the gas in the oil and gas reservoir gas storage to the distribution users in the distribution network.

[0057] In order to improve the productivity of the gas storage, the gas injection and production station of the gas storage needs to be reformed in combination with the industrial gas and residential gas in the area where the gas storage is located. After the pressure of the gas storage is reduced to the pipeline pressure, the channel between the gas storage and the pipeline is cut off, the surplus pressure of the gas storage is utilized by increasing the downstream users, the reservoir pressure of the gas storage is continuously exploited to the lower limit pressure, the productivity of the gas storage is fully utilized, the utilization efficiency of the gas storage is improved, and the economic benefit of the gas storage is improved as much as possible.

[0058] Optionally, the distribution pressure of the distribution network is lower than the preset pipeline pressure.

[0059] Optionally, in an example embodiment, the oil and gas reservoir gas storage productivity control system further comprises a hydraulic storage tank configured for the oil and gas reservoir gas storage; after the gas in the oil and gas reservoir gas storage is produced, the gas is pressurized, cooled, and compressed to the hydraulic storage tank, and then is transported to scattered users by tank car.

[0060] In the embodiment of the application, after the pressure of the gas storage is reduced to the pipeline pressure, the channel between the gas storage and the pipeline is cut off, the surplus pressure of the gas storage is utilized by increasing the liquefied natural gas / compressed natural gas device, the reservoir pressure of the gas storage is continuously exploited to the lower limit pressure, the productivity of the gas storage is fully utilized, the utilization efficiency of the gas storage is improved, and the economic benefit of the gas storage is improved as much as possible.

[0061] The embodiment of the application further provides a computer readable storage medium, which comprises instructions, when the instructions are run on a computer, the computer executes the oil and gas reservoir gas storage productivity control method provided in any of the above embodiments.

[0062] The embodiment of the application further provides an electronic device, which comprises a memory, a processor, and a computer program stored in the memory and executable on the processor, when the processor executes the program, the oil and gas reservoir gas storage productivity control method provided in any of the above embodiments is realized.

[0063] The embodiment of the application further provides a computer program product, which comprises computer instructions stored in a computer readable storage medium. A processor of a computer device reads the computer instructions from the computer readable storage medium, and the processor executes the computer instructions, so that the computer device executes the oil and gas reservoir gas storage productivity control method provided in the various optional embodiments.

[0064] The technical solutions of the application are further described in detail below in combination with a specific example. Figure 3A schematic diagram of a gas production process of a gas storage is provided for an exemplary embodiment of the present application.

[0065] As shown in Figure 3 , the underground gas storage is connected to a gas storage well field, the gas storage well field is connected to a station, the station is connected to a long-distance pipeline, and a valve connected to a trunk line is arranged on a pipeline connecting the station and the long-distance pipeline. The station is also directly connected to a distribution network and a distribution user (which can include multiple distribution users, only user 1 is shown in the figure), and the station is also connected to a liquefied tank. Figure 3 When the outlet pressure of the injection-production station is lower than the preset pipeline network pressure, the produced gas in the gas storage is pressurized and cooled, and is compressed to a liquid pressure tank (i.e., the liquefied tank in the figure) for convenient transportation to scattered users (such as user 2 in the figure) by tank car. Figure 3

[0066] It is assumed that the design and operation pressure of the gas storage in the embodiment of the present application is 5-12 MPa, and during the winter supply period, the pressure of the pipeline network connected to the gas storage is about 6 MPa at the lowest. When the wellhead pressure is extracted to 7 MPa, the outlet pressure of the produced gas is lower than the pipeline network pressure due to the influence of the pipeline network operation pressure, and the produced gas cannot be transported to the pipeline network, the gas production period ends in advance, and the gas storage reservoir is not effectively utilized, and the production capacity of the gas storage is not effectively utilized.

[0067] Based on this working condition, two distribution users with distribution pressures of 3.8 MPa and 4.2 MPa, respectively, and one compressed natural gas user are designed for the gas storage, and the channel between the gas storage and the gas trunk line is cut off after the outlet pressure is equal to the pipeline network pressure, and the downstream users are directly supplied by the gas storage.

[0068] During the 2022-2023 winter supply period, the gas storage uses the oil and gas reservoir gas storage production capacity regulation method provided in the embodiment of the present application to produce 19.02 million cubic meters of gas from February 12 to March 10. During the 2023-2024 winter supply period, the gas storage uses the oil and gas reservoir gas storage production capacity regulation method provided in the embodiment of the present application, and accumulates 8.3 million cubic meters of gas from February 5 to February 26.

[0069] As can be seen from the above example, by configuring a distribution user or a liquid pressure tank for the oil and gas reservoir gas storage, the embodiment of the present application can effectively increase the produced gas amount of the gas storage, increase the gas injection amount, and improve the utilization rate of the gas storage. In the later gas production period, the pipeline network supplies gas to downstream users, reduces the pipeline storage pressure during the gas consumption peak period, and slows down the pipeline network gas transmission pressure. The gas storage plays a role in peak shaving, effectively increases the working gas amount, shortens the pipeline transportation distance of the consignor, directly supplies downstream users from the gas storage, reduces the pipeline transportation cost, increases the gas storage storage and transfer fee income, shortens the gas storage payback time, reduces the running time of the gas storage branch line, and appropriately reduces the trunk line maintenance content according to the actual needs.
