Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas reservoir type gas storage, and in particular to a production capacity control method of an oil and gas reservoir type gas storage and related equipment. Background Art

[0002] Depleted oil and gas reservoir gas storage is built using depleted gas or oil layers. It is currently the most commonly used and most economical form of underground gas storage due to its large gas storage capacity, fast transformation speed, reliable operation, and wide peak-shaving range. It accounts for more than 75% of the total number of underground gas storages, and plays an increasingly important role in my country's natural gas supply and peak-shaving.

[0003] To ensure the safe, efficient and stable operation of gas storages, they should operate within a set pressure range. Most of my country's gas storages are buried at a large depth and have a high operating pressure range. The operating pressure of the national pipeline network is about 6-11MPa. Most of my country's oil and gas reservoirs are buried at a large depth and have a lower limit pressure higher than the operating pressure of the national pipeline network. Therefore, the pipeline system can receive gas sources from various gas storages at any time to maximize the production capacity of the gas storages.

[0004] However, there are still some gas storage reservoirs whose lower limit pressure is lower than the pipeline network operating pressure. When the formation pressure of the gas storage reservoir drops to the pipeline network pressure, the gas production process needs to be stopped in advance due to the pressure. The working gas of the gas storage reservoir cannot be fully produced, and the maximum production capacity of the gas storage reservoir cannot be utilized. Summary of the invention

[0043] S3, continuously extracting gas from the oil and gas reservoir through a preset gas extraction plan until the preset lower limit pressure is reached and gas extraction is stopped.

[0044] In the embodiment of the present invention, by real-time monitoring of the outlet pressure of the injection and production station of the oil and gas reservoir gas storage, when it is monitored that the outlet pressure of the injection and production station is lower than the preset pipeline network pressure, the channel between the oil and gas reservoir gas storage and the pipeline network is cut off, and the oil and gas reservoir gas storage is continuously produced through a preset gas production plan, which can effectively increase the gas production of the gas storage, and at the same time increase the gas injection volume, give full play to the peak regulation role of the gas storage, and improve the utilization rate of the gas storage; reduce the pipeline storage pressure during the peak gas consumption period, and ease the gas transmission pressure of the pipeline network; increase the storage and transfer fee income of the gas storage, and shorten the payback time of the gas storage; reduce the operating time of the gas storage branch line, and appropriately reduce the main line maintenance content according to actual needs.

[0045] Optionally, in an exemplary embodiment, continuous gas production is performed on an oil and gas reservoir storage reservoir through a preset gas production plan, including: transporting the stored gas in the oil and gas reservoir storage reservoir to distribution users in the distribution network through a pre-established distribution network.

[0046] In order to increase the production capacity of gas storage, it is necessary to transform the injection and production station of gas storage in combination with the industrial and residential gas consumption in the area where the gas storage is located. Specifically, in areas suitable for the construction of oil and gas reservoir gas storage, the gas demand of local industrial and residential users should be fully investigated, and a distribution network should be established during the construction of the gas storage, and distribution users should be configured.

[0047] In general, the pressure of downstream distribution users is about 3-5MPa, which is much lower than the lower limit operating pressure of the gas storage. During the gas production process of the gas storage, when it is monitored that the pressure of the gas storage drops to the pipeline pressure, the channel between the gas storage and the pipeline is cut off, and gas supply to the natural gas pipeline is stopped. Instead, gas is supplied to distribution users, and the residual pressure of the gas storage is used to continue gas production. The reservoir pressure of the gas storage is continuously exploited to the lower limit pressure, so as to give full play to the production capacity of the gas storage and improve the utilization efficiency of the gas storage. As much gas as possible is produced to improve the economic benefits of the gas storage.

[0048] Optionally, the distribution pressure of the distribution network is lower than the preset pipeline pressure. The distribution pressure of the distribution network is lower than the preset pipeline pressure. After the gas storage pressure drops to the pipeline pressure, the reservoir pressure of the gas storage can be continuously exploited to the lower limit pressure, so as to give full play to the production capacity of the gas storage, improve the utilization efficiency of the gas storage, and extract as much gas as possible to improve the economic benefits of the gas storage.

[0049] Optionally, in an exemplary embodiment, gas is continuously extracted from an oil and gas reservoir gas storage reservoir through a preset gas extraction plan, including: configuring a hydraulic storage tank for the oil and gas reservoir gas storage reservoir, pressurizing and cooling the gas extracted from the oil and gas reservoir gas storage reservoir, and compressing it into the hydraulic storage tank, so as to facilitate its transportation to scattered users by tank trucks.

[0050] In the embodiment of the present invention, during the gas production process of the gas storage, when it is monitored that the pressure of the gas storage drops to the pipeline pressure, the passage between the gas storage and the pipeline is cut off, and gas supply to the natural gas pipeline is stopped. Instead, the residual pressure of the gas storage is used to continue gas production by liquefying and compressing natural gas, and the reservoir pressure of the gas storage is continuously produced to the lower limit pressure. While giving full play to the production capacity of the gas storage, the utilization efficiency of the gas storage is improved, and as much gas as possible is produced to improve the economic benefits of the gas storage.

[0051] Figure 2 This is a block diagram of an oil and gas reservoir gas storage capacity control system according to an exemplary embodiment of the present application. Figure 2 As shown, the oil and gas reservoir gas storage capacity control system includes: a pressure monitoring module and a main control module.

[0052] The pressure monitoring module is used to monitor the outlet pressure of the injection and production station of the oil and gas reservoir in real time;

[0053] The main control module is used to cut off the passage between the oil and gas reservoir and the pipeline network when the outlet pressure of the injection and production station is lower than the preset pipeline network pressure; it is also used to continuously produce gas from the oil and gas reservoir through a preset gas production plan until the preset lower limit pressure is reached and gas production is stopped.

[0054] In the embodiment of the present invention, when it is monitored that the outlet pressure of the injection and production station is lower than the preset pipeline pressure, the passage between the oil and gas reservoir gas storage and the pipeline is cut off, and the oil and gas reservoir gas storage is continuously produced through the preset gas production plan. Compared with the traditional gas production method of only supplying gas to the pipeline and stopping production when the pressure is equal to the pipeline pressure, the gas production volume of the implementation scheme of the present invention is significantly increased, and the amount of gas that can be injected in the next stage is also increased, and the annual injection and production gas volume is increased. The reservoir voids near the bottom of the well are fully flushed, the permeability around the well is improved, the skin coefficient is reduced, the bottom of the well pollution is improved, and the gas injection and production capacity of a single well is further improved, which is conducive to the gas storage to reach full capacity and production.

[0055] The embodiments of the present invention can effectively increase the gas output of the gas storage and increase the gas injection volume at the same time, give full play to the peak-shaving effect of the gas storage, and improve the utilization rate of the gas storage; reduce the pipeline storage pressure during the peak gas consumption period and ease the gas transmission pressure of the pipeline network; increase the storage and transfer fee income of the gas storage and shorten the payback time of the gas storage; reduce the operating time of the gas storage branch line, and appropriately reduce the maintenance content of the trunk line according to actual needs.

[0056] Optionally, in an exemplary embodiment, the oil and gas reservoir gas storage facility capacity control system also includes a pre-established distribution network; the pre-established distribution network is used to transport the stored gas in the oil and gas reservoir gas storage facility to distribution users in the distribution network.

[0057] In order to increase the production capacity of the gas storage, it is necessary to transform the gas storage injection and production station in combination with the industrial and residential gas consumption in the area where the gas storage is located. After the pressure of the gas storage drops to the pipeline pressure, the channel between the gas storage and the pipeline is cut off, and the residual pressure of the gas storage is used to continue gas production by increasing downstream users. The reservoir pressure of the gas storage is continuously exploited to the lower limit pressure, so as to give full play to the production capacity of the gas storage, improve the utilization efficiency of the gas storage, and extract as much gas as possible to improve the economic benefits of the gas storage.

[0058] Optionally, the distribution pressure of the distribution network is lower than the preset pipeline pressure. The distribution pressure of the distribution network is lower than the preset pipeline pressure. After the gas storage pressure drops to the pipeline pressure, the reservoir pressure of the gas storage can be continuously exploited to the lower limit pressure, so as to give full play to the production capacity of the gas storage, improve the utilization efficiency of the gas storage, and extract as much gas as possible to improve the economic benefits of the gas storage.

[0059] Optionally, in an exemplary embodiment, the oil and gas reservoir gas storage reservoir capacity control system also includes a hydraulic storage tank configured for the oil and gas reservoir gas storage reservoir; the gas stored in the oil and gas reservoir gas storage reservoir is pressurized and cooled after being produced, and compressed into the hydraulic storage tank, so as to be transported to scattered users by tank trucks.

[0060] In the embodiment of the present invention, after the pressure of the gas storage reservoir drops to the pipeline pressure, the passage between the gas storage reservoir and the pipeline network is cut off, and the residual pressure of the gas storage reservoir is used to continue gas extraction by adding a liquefied natural gas / compressed natural gas device, and the reservoir pressure of the gas storage reservoir is continuously extracted to the lower limit pressure, so as to give full play to the production capacity of the gas storage reservoir, improve the utilization efficiency of the gas storage reservoir, extract as much gas as possible, and improve the economic benefits of the gas storage reservoir.

[0061] An embodiment of the present invention further provides a computer-readable storage medium, comprising instructions, which, when executed on a computer, enable the computer to execute the method for controlling the production capacity of an oil and gas reservoir provided in any of the above embodiments.

[0062] An embodiment of the present invention also provides an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the method for controlling the production capacity of an oil and gas reservoir provided in any of the above embodiments is implemented.

[0063] The embodiment of the present invention further provides a computer program product, which includes computer instructions, and the computer instructions are stored in a computer-readable storage medium. The processor of the 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 capacity control method provided in the above various optional embodiments.

[0064] The technical solution of the present invention is further described in detail below in conjunction with a specific example. Figure 3A schematic diagram of a gas storage gas production process provided by an exemplary embodiment of the present invention.

[0065] like Figure 3 As shown, the underground gas storage is connected to the gas storage well field, the gas storage well field is connected to the station, the station is connected to the long-distance pipeline, and the pipeline connecting the station and the long-distance pipeline is provided with a valve connected to the trunk line. The station is also directly connected to the distribution users (which may include multiple distribution users, Figure 3 Only user 1 is shown in the figure. The station is also connected to a liquefied gas tank. When the outlet pressure of the injection and production station is lower than the preset pipeline pressure, the gas in the gas storage reservoir is produced, pressurized and cooled, and compressed into a hydraulic storage tank (i.e., the liquefied gas tank in the figure) to facilitate transportation to scattered users (such as Figure 3 User 2).

[0066] Assuming that the design operating pressure of the gas storage in the embodiment of the present invention is 5-12MPa, during the winter supply guarantee period, the minimum pressure of the pipeline network connected to the gas storage is about 6MPa. When the wellhead pressure reaches 7MPa, affected by the operating pressure of the pipeline network, the outlet pressure of the produced gas is lower than the pipeline network pressure, and the produced gas cannot be transported to the pipeline network. The gas production period ends prematurely, the reservoir inventory is not effectively utilized, and the production capacity of the gas storage is not effectively utilized.

[0067] Based on this operating condition, two distribution users are designed for the gas storage, with distribution pressures of 3.8MPa and 4.2MPa respectively, and one compressed natural gas user. When the outlet pressure reaches the same level as the pipeline pressure, the channel between the gas storage and the gas transmission trunk line is cut off, and the gas storage directly supplies downstream users.

[0068] During the 2022-2023 winter supply guarantee period, the gas storage reservoir used the oil and gas reservoir gas storage capacity control method provided by the embodiment of the present invention from February 12 to March 10 to produce 19.02 million cubic meters of gas. During the 2023-2024 winter supply guarantee period, the gas storage reservoir used the oil and gas reservoir gas storage capacity control method provided by the embodiment of the present invention from February 5 to February 26 to produce a total of 8.3 million cubic meters of gas.

[0069] According to the above examples, it can be seen that the embodiments of the present invention can effectively increase the gas production of the gas storage by configuring the oil and gas reservoir gas storage with distribution users or hydraulic storage tanks, while increasing the gas injection volume and improving the utilization rate of the gas storage. In the later stage of gas production, the pipeline network is replaced to transmit gas to downstream users, reducing the pipeline storage pressure during the peak period of gas consumption and alleviating the gas transmission pressure of the pipeline network. Give full play to the peak-shaving role of the gas storage and effectively increase the working gas volume. Shorten the pipeline transmission distance of the consignor, and directly supply the downstream users from the gas storage to reduce the pipeline transmission fee. Increase the storage and transfer fee income of the gas storage and shorten the payback time of the gas storage. Reduce the operating time of the gas storage branch line, and appropriately reduce the maintenance content of the trunk line according to actual needs.
