[0029] Embodiment 1

[0030] Figure 1 It is a flowchart of a method for increasing the production of a natural gas platform well group according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of dealing with the production problems of each well in the natural gas well group. This method can be executed by a device for increasing the production of a natural gas platform well group, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. As Figure 1 shown, the method includes:

[0031] S110. Collect the production information of each well in the natural gas platform well group.

[0032] In this solution, Figure 2 is a schematic diagram of a composite production increase module for a platform well group provided in Embodiment 1 of the present application. As Figure 2 shown, the overall area includes the natural external transportation process of the natural gas platform well group and the composite measure production increase module of the platform well group. Among them, the natural external transportation process of the natural gas platform well group may refer to that the platform gas wells do not rely on any external measure intervention, the single-well wellhead pressure is higher than the trunk pipeline network pressure, the daily gas production basically meets the requirement of liquid carrying, the formation liquid production and the wellhead liquid production are basically balanced, and the gas produced by the platform well group is naturally concentrated to the trunk pipeline for external transportation. The composite measure production increase module of the platform well group refers to automatically executing the matching production increase module by collecting and classifying the single-well production information. When there is liquid accumulation in the wellbore of a single well or multiple wells in the platform well group, the foam drainage or gas lift process is implemented according to the different degrees of liquid accumulation, and the single well or multiple well wellhead pressure is lower than the trunk pipeline network pressure, and pressurized external transportation is implemented. Among them, gas lift is an artificial lift technology, which injects relatively high-pressure gas from the ground into the wellbore (mainly between the casing and the production tubing) through a valve installed at a critical depth in the oil well. The injected gas enters the valve and mixes with the fluid in the production tubing. After mixing, the liquid density decreases, so that the oil reservoir pressure at the bottom of the well can lift the oil to the ground. By maintaining the ground gas injection speed and the ratio of the injected gas to the wellbore fluid stable, the oil well will produce oil at a stable rate. Foam drainage is to inject a surfactant into the bottom of the well. With the agitation of the natural gas flow, after fully contacting the bottom-hole liquid accumulation, a large amount of relatively stable low-density water-containing foam is generated. The foam carries the bottom-hole liquid accumulation to the ground along with the gas flow, so as to achieve the purpose of drainage gas production.

[0033] In this embodiment, the production information includes the oil pressure, casing pressure, daily gas production, and dynamic liquid level data. The oil pressure refers to the remaining pressure after the flowing pressure lifts the oil and gas from the bottom of the well to the wellhead through the tubing, which is called the tubing pressure; the casing pressure, that is, the casing pressure, refers to the pressure applied to the casing in the well on the ground; the dynamic liquid level refers to that when the pumping well is in normal production, there is a liquid level in the annular space between the tubing and the casing. Specifically, the oil pressure, casing pressure, daily gas production, and dynamic liquid level data of each well in the natural gas platform well group can be collected based on a pre-determined composite measure production increase collection module.

[0034] S120. Classify the type of each well according to the production information of each well to obtain target wells; where the target wells include gas lift target wells, foam drainage target wells, boosting target wells, natural production wells, and abandoned pressure wells.

[0035] In this solution, based on a pre-determined composite measure production increase classification module, the oil pressure, casing pressure, daily gas production volume, and flowing fluid level data of each well can be analyzed, and each well in the natural gas platform well group can be classified into gas lift target wells, foam drainage target wells, boosting target wells, natural production wells, and abandoned pressure wells. Among them, the natural production wells produce gas and enter the natural external transmission process, and the abandoned pressure wells are shut down and production stops.

[0036] Specifically, based on the composite measure production increase classification module, determine and screen out the severely liquid-loaded wells with a flowing fluid level immersion depth greater than 500m and less than 1500m as gas lift target wells, or screen out the severely liquid-loaded wells with an oil-casing pressure difference greater than 5MPa as gas lift target wells; screen out the slightly liquid-loaded wells with a flowing fluid level immersion depth less than 500m or an oil-casing pressure difference less than 3MPa as foam drainage target wells; screen out the low-pressure potential wells with an oil pressure greater than 0.1Mpa but less than the gathering main pipeline pressure as boosting target wells.

[0037] S130. Determine the production increase measure module corresponding to the target wells, and process the target wells based on the production increase measure module to achieve production increase of the natural gas platform well group.

[0038] In this solution, the production increase measure module can include a gas lift module, a foam drainage module, a boosting module, and a production increase execution module. The gas lift module is used to discharge the liquid when severe wellbore liquid loading occurs in a single well or multiple wells of the platform well group. To start the gas lift module, it is necessary to control the electric valve group to connect the gas source inlet (casing gas of the platform well group or gas in the gathering main pipeline network), the gas lift outlet, and the oil-casing annulus inlet of the gas lift target well to form a passage; the foam drainage module is used to improve the liquid-lifting efficiency when slight wellbore liquid loading occurs in a single well or multiple wells of the platform well group. To start the foam drainage module, it is necessary to control the electric valve group to connect the foam drainage outlet and the oil-casing annulus inlet of the foam drainage target well to form a passage; the boosting module is used to boost the pressure when the tubing pressure of a single well or multiple wells in the platform well group is lower than the pressure of the main pipeline network. To start the boosting module, it is necessary to control the electric valve group to connect the tubing of the boosting target well, the gas source inlet, and the boosting external output outlet to form a passage. The production increase execution module starts the corresponding gas lift, foam drainage, and boosting modules for the target wells, monitors the temperature, pressure, displacement, etc. information of each part during the operation of each module. At the same time, the composite production increase acquisition module real-time collects the oil pressure, casing pressure, daily gas production volume, and flowing fluid level condition of the target wells, and the classification module re-matches the measure module selection.

[0039] In this embodiment, Figure 3 is the flow chart of the differential natural gas platform well group production increase process method provided in Embodiment 1 of this application, as Figure 3As shown in the figure, the composite measure production increase acquisition module acquires the oil pressure, casing pressure, daily gas production, and flowing fluid level data of each well in the gas production platform well group; the composite measure production increase classification module classifies each well into gas lift target wells, foam drainage target wells, pressurization target wells, natural production wells, etc. The production increase execution module starts the corresponding gas lift, foam drainage, and pressurization modules for the target wells, and centrally controls the ground pipelines and electric control gate switches of the target wells. During the implementation of pressurization measures such as gas lift, foam drainage, and pressurization by the module, temperature, pressure, and displacement data are acquired in real time. And the composite production increase acquisition module acquires the oil pressure, casing pressure, gas production, and flowing fluid level data during the implementation of the measures, and re-matches the production increase measure module for the target wells according to the data acquisition situation. When the target well resumes natural production, the production increase measure module of the next target well is executed until all the wells in the platform well group can produce naturally; otherwise, it is repeated to achieve the production increase of the gas production platform well group.

[0040] Optionally, the production increase measure module includes a gas lift module, a foam drainage module, a pressurization module, and a production increase execution module;

[0041] Correspondingly, determining the production increase measure module corresponding to the target well and processing the target well based on the production increase measure module includes:

[0042] If the production increase measure module corresponding to the target well is a gas lift module, the gas in the gathering and transportation main pipeline network or the neighboring well gas on the same platform is used as the gas lift circulation medium, and after being triple-pressurized by the gas lift module, it is injected into the oil-casing annulus of the target well through the gas lift outlet, and the accumulated liquid is discharged through the inner channel of the tubing in a circulating manner.

[0043] In this solution, when severe wellbore liquid accumulation occurs in a single well or multiple wells in the platform well group, the gas in the gathering and transportation main pipeline network or the neighboring well gas on the same platform is taken as the gas lift circulation medium, and after being triple-pressurized by the gas lift module, it is injected into the oil-casing annulus of the target well through the gas lift outlet, and the accumulated liquid is discharged through the inner channel of the tubing in a circulating manner.

[0044] Specifically, for the severely liquid-accumulated well, when the gas lift module is executed, the gas lift gas source can be the gas in the gathering main pipeline network, or the single-well casing gas with a casing pressure greater than 3 MPa and less than 6 MPa and an instantaneous flow greater than 600 Nm 3 / h in the platform well group. After being triple-pressurized by the gas lift module, the output pressure can reach up to 23 MPa at most, and the output displacement is greater than 600 Nm 3 / h; The pressurization execution module controls the on - ground pipeline, wellhead, and the switch states of the electric control gates to form a passage. The high - pressure gas source is injected into the annulus between the casing of the target well through the gas lift outlet of the gas lift module, and the accumulated liquid is discharged through the tubing circulation and enters the natural external transportation process. During the implementation of the gas lift module, the submergence depth of the moving liquid level and the casing - tubing pressure difference of the target well are collected. When the submergence depth of the moving liquid level is less than 500 m or the casing - tubing pressure difference is less than 3 MPa, the implementation of the gas lift module can be stopped and switched to the implementation of the foam drainage module. The foam drainage agent is injected into the annulus between the casing of the target well through the foam drainage outlet, and the injection regime is carried out according to the conventional foam drainage process until the submergence depth of the moving liquid level of the target well no longer increases or the casing - tubing pressure difference is less than 1.5 MPa. If the situation of increased accumulated liquid occurs, the foam drainage module can be implemented again; for newly added severely accumulated liquid wells in the platform well group, the gas lift module and the foam drainage module are repeatedly executed.

[0045] By implementing the gas lift module to discharge the accumulated liquid in the target well, it can improve the overall daily gas production of the differential platform well group. At the same time, it effectively avoids the complexity of production - increasing equipment types, repeated installation, and repeated well - going by personnel. The measures are automatically and timely intervened, reducing production costs and labor intensity of personnel, and enhancing the development efficiency of the platform well group.

[0046] Optionally, determining the production - increasing measure module corresponding to the target well and processing the target well based on the production - increasing measure module further includes:

[0047] If the production - increasing measure module corresponding to the target well is the foam drainage module, a drip - feeding pump is used to inject the foam drainage agent into the casing of a single well or multiple wells, and it is injected into the annulus between the casing of the target well through the foam drainage outlet.

[0048] In this embodiment, when mild wellbore accumulated liquid occurs in a single well or multiple wells of the platform well group, a drip - feeding pump is used to inject the foam drainage agent into the casing of a single well or multiple wells, and it is injected into the annulus between the casing of the target well through the foam drainage outlet to improve the lifting efficiency of the accumulated liquid.

[0049] Specifically, for mildly accumulated liquid wells, the foam drainage module is executed, and at the same time, the switch states of the on - ground pipeline, wellhead, and electric control gates are controlled to form a foam drainage passage, and the foam drainage agent is injected into the annulus between the casing of the target well through the foam drainage outlet.

[0050] By implementing the foam drainage module, the lifting efficiency of the accumulated liquid can be improved, thereby improving the overall daily gas production of the differential platform well group. At the same time, it effectively avoids the complexity of production - increasing equipment types, repeated installation, and repeated well - going by personnel. The measures are automatically and timely intervened, reducing production costs and labor intensity of personnel, and enhancing the development efficiency of the platform well group.

[0051] Optionally, determining the production - increasing measure module corresponding to the target well and processing the target well based on the production - increasing measure module further includes:

[0052] If the stimulation measure module corresponding to the target well is a pressurization module, in the case where the tubing pressure of a single well or multiple wells is lower than the main pipeline network pressure, pressurization is carried out by relying on a single set or a double set of compressor units according to different tubing pressures, so that the pressure after pressurization is higher than the main pipeline pressure, and it enters the gas gathering main pipeline through the pressurized export pipeline.

[0053] In this embodiment, when the tubing pressure of a single well or multiple wells in the platform well group is lower than the main pipeline network pressure, pressurization is carried out by relying on a single set or a double set of compressor units according to different tubing pressures, so that the pressure after pressurization is higher than the main pipeline pressure, and it enters the gas gathering main pipeline through the pressurized export pipeline.

[0054] Specifically, execute the pressurization module, and at the same time control the on-off states of the surface pipeline, wellhead, and electric control gate to form a pressurization path, and enter the gas gathering main pipeline through the pressurized export; according to the oil pressure of different target wells, the control assembly selects to perform primary or secondary pressurization to ensure that the pressure after pressurization is higher than the gas gathering main pipeline pressure; if there is liquid accumulation in the target well of the pressurization module, the above steps can be re-executed for auxiliary liquid drainage; when the pressurization module is implemented for the target well and other liquid accumulation wells need to perform the gas lift module in the platform well group, the pressurization module can be temporarily stopped, and the gas lift module is preferentially executed. After the target well of the gas lift module resumes natural production, the pressurization module is re-implemented.

[0055] Further, for the low-pressure potential well transformed into an abandoned pressure well, close the electric control gate of the target well and shut down the well for production suspension.

[0056] By executing the pressurization module, the total daily gas production of the differential platform well group can be increased. At the same time, it effectively avoids the complexity of stimulation equipment types, repeated installation, and repeated well visits by personnel. The measures are automatically and timely intervened, reducing production costs and labor intensity of personnel, and improving the development efficiency of the platform well group.

[0057] Optionally, determining the stimulation measure module corresponding to the target well and processing the target well based on the stimulation measure module further includes:

[0058] If the stimulation measure module corresponding to the target well is a stimulation execution module, centrally control the start and stop of the gas lift module, foam drainage module, and pressurization module, and control all electric control valves, connecting pipelines, temperature, pressure, and flow sensors of the natural gas platform well group, and collect the temperature, pressure, and displacement data of the gas lift outlet, foam drainage outlet, and pressurized export to achieve synchronous switching of the target well of the natural gas platform well group.

[0059] In this solution, when the gas production of the gas platform well group needs to be increased, the centralized control of the gas lift module, foam drainage module, and pressurization module is implemented for start and stop. The centralized control of all the electric control valves, connecting pipelines, temperature, pressure, and flow sensors of the platform well group is carried out. The temperature, pressure, and displacement data of the gas lift outlet, foam drainage outlet, and pressurization external output outlet are collected centrally to realize the synchronous switching of the composite production increase measure module and the target wells of the platform well group.

[0060] Through the automatic selection and optimized implementation of the production increase execution module, overall matching measures are implemented for the platform well group. By continuously collecting data, automatically judging, selecting target wells, and implementing measures, the overall daily gas production of the differentiated platform well group can be increased. At the same time, it effectively avoids the complexity of production increase equipment, repeated installation, and repeated well visits by personnel. The measures are automatically and timely intervened, reducing production costs and the labor intensity of personnel, and improving the development efficiency of the platform well group.

[0061] Optionally, the method further includes:

[0062] Controlling the industrial power grid or gas generator of the gas platform well group to provide power drive for the production increase execution module.

[0063] Specifically, the industrial power grid or gas generator of the platform well group where it is located can be selected to provide power drive for the composite measure production increase measure module.

[0064] Optionally, the treatment of the target well includes:

[0065] Processing the target well according to the preset priority; among them, the treatment order of the target well is the gas lift target well, the foam drainage target well, and the pressurization target well in sequence.

[0066] In this solution, if there are implementation requirements for the pressurization module, foam drainage module, and gas lift module in the gas wells of the platform well group at the same time, considering that the gas lift implementation period is short, the effect is quick, and the production increase potential of the target well is large, the gas lift target well can be preferentially implemented, followed by the foam drainage target well and the pressurization target well.

[0067] By setting priorities to process the target wells, the implementation period can be shortened and the production increase potential of the target wells can be improved.

[0068] The technical solution of the embodiment of the present invention collects the production information of each well in the gas platform well group, divides the type of each well according to the production information of each well to obtain the target wells. Then, the production increase measure module corresponding to the target wells is determined, and the target wells are processed based on the production increase measure module to achieve the production increase of the gas platform well group. By implementing this technical solution, the overall daily gas production of the differentiated platform well group is increased. At the same time, it effectively avoids the complexity of production increase equipment, repeated installation, and repeated well visits by personnel. The measures are automatically and timely intervened, reducing production costs and the labor intensity of personnel, and improving the development efficiency of the platform well group.

[0069] In this solution, a total of 6 production wells, namely A, B, C, D, E, and F, are arranged in a platform well group. Based on the composite production enhancement acquisition module, the production information of the production wells is collected. It can be determined that the flowing fluid level depth of Well A is 1850 m, the flowing fluid level depth of Well E is 1300 m, and the tubing pressure of Well B is 0.3 MPa, and the pressure of the gas gathering main line is 3.5 MPa. The composite measure production enhancement classification module determines that Well A and Well E are severely liquid-accumulating wells and need to implement the gas lift module and the foam drainage module. Moreover, the liquid accumulation degree of Well A is higher than that of Well E. Therefore, Well A is preferentially taken as the target well. Well B is determined as the pressurization target well. Therefore, the production enhancement execution module of this well group issues an instruction to sequentially execute the gas lift and foam drainage modules on Wells A and E, and then implement the pressurization module on Well E.

[0070] Specifically, as Figure 2 shown, the initial states of the electric control valves of the platform well group A1 - F2, J1, Q1, P1, and Z1 are all fully closed, and the states of A out - F out are normally open. Well C of the platform well group meets the requirements of the gas source inlet and serves as the gas lift gas source. The production enhancement execution module opens the electric control valves C2, A2, J1, and Q1, introduces the casing gas of Well C into the gas source inlet, and after three - stage pressurization by the gas lift module, it enters the annulus between the tubing and the casing of Well A through the gas lift outlet pipeline and the electric control valve A2, and starts to implement the gas lift liquid drainage process. The production enhancement measure module and the composite production enhancement analysis module continuously monitor the flowing fluid level depth and instantaneous gas production of Well A. When the flowing fluid level depth gradually drops below 500 m, the execution module issues an instruction to close the electric control valves C2, J1, and Q1, stop the operation of the gas lift module, start the foam drainage module, and open the electric control valve P1. The foam drainage liquid is injected into the annulus between the tubing and the casing of Well A through the foam drainage outlet and the electric control valve A2 to complete the injection of the foam drainage agent. After Well A can produce naturally, the production enhancement execution module issues an instruction to close the foam drainage module, the electric control valve P1, and the electric control valve A2. After the implementation of the gas lift and foam drainage modules on Well A is completed, the process switches to Well E to implement the gas lift module and the foam drainage module. After Well E can produce naturally, the relevant process electric control valves are closed.

[0071] Furthermore, after the implementation of the gas lift module on Wells A and E is completed, the pressurization module is implemented for Well B. Close the electric control valve B out (A1 is in the closed state), open the electric control valves B1, J1, and Z1. In this way, the low - pressure gas source of Well B enters the pressurization module through J1 and is pressurized and exported to the gas gathering main line after two - stage compression. When the wellhead pressure of Well B does not meet the minimum pressure requirement of the gas source inlet and the pressure can be quickly restored through well - shutting operation, the pressurization execution module can pause the pressurization module, close B1 and B out, and wait for the pressure to recover to meet the minimum gas source inlet pressure, and then re - execute the pressurization module. When the pressure of Well B recovers slowly after a long - time well - shutting and is still 0.1 MPa lower than the minimum wellhead pressure of the gas source, the classification module determines it as an abandoned pressure well and shuts down the well for production suspension. The composite measure production enhancement module implements the gas lift, foam drainage, and pressurization modules for other wells in the platform well group and repeats the implementation.
