Description

Technical Field

[0001] This application relates to the field of underground water-sealed cavern technology, and in particular to a method, apparatus, equipment and storage medium for zoning test of the effectiveness of water curtain in underground water-sealed caverns. Background Technology

[0002] A water-sealed underground cavern is a type of underground storage facility that utilizes a stable groundwater level to create a "water seal" for the safe storage of flammable and explosive media such as petroleum. The water curtain system, as a key structure, continuously injects water through water curtain tunnels and water curtain orifices above the storage cavern to maintain a groundwater level above the cavern's top, thereby preventing oil leakage. To ensure the water curtain system possesses good sealing performance and hydraulic connectivity, water curtain effectiveness tests must be conducted during the construction and operation phases to assess the connectivity between water curtain orifices, verify the water seal effect, and guide the optimized arrangement of additional water curtain orifices.

[0003] Traditional water curtain effectiveness tests typically involve testing the entire water curtain system (containing more than 500 water curtain orifices) as a whole simultaneously. During the test, the opening and closing status of all water curtain orifices must be controlled at the same time, and data such as pressure, flow rate, and water level at each orifice must be collected. Multi-stage hydrodynamic disturbances are then used to determine the system's connectivity and sealing performance.

[0004] Due to the large scale and complex structure of the water curtain system, the overall synchronous test faces challenges such as difficult coordination, long construction period, large data acquisition volume, and susceptibility to interference, resulting in low test efficiency and difficulty in ensuring data quality. Furthermore, if an anomaly occurs in a certain area, it is difficult to quickly locate the problem area, further affecting the accuracy of the test and the project progress. Therefore, how to improve the test efficiency and ensure the reliability of test results in the effectiveness test of the water curtain in underground water-sealed caverns has become an urgent problem to be solved.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] The purpose of this application is to provide a method, apparatus, equipment and storage medium for zonal testing of the effectiveness of water curtain in underground water-sealed caverns, aiming to solve the technical problem of how to improve test efficiency and ensure the reliability of test results in the testing of the effectiveness of water curtain in underground water-sealed caverns.

[0007] To achieve the above objectives, this application proposes a zoning test method for the effectiveness of water curtain in underground water-sealed caverns, the method comprising: The water curtain system was divided into multiple primary test zones according to the project sections; Using the area enclosed by the water curtain tunnel and the construction tunnel as the boundary, each of the primary test zones is divided into multiple secondary test zones; For each of the secondary test zones, effectiveness tests were conducted sequentially, including a natural hydrostatic pressure recovery phase, a first hydrodynamic state phase, and a second hydrodynamic state phase. During the effectiveness test, the pressure, flow rate, and water level data of each water curtain hole and the water level monitoring hole are recorded to complete the effectiveness zone test.

[0008] In one embodiment, the step of dividing the water curtain system into multiple primary test zones according to engineering sections includes: Obtain the engineering section division documents and overall layout information of the water curtain system for the underground water-sealed cavern; The geographical boundaries of each engineering section are clearly defined according to the engineering section division document. Based on the overall layout information of the water curtain system, determine the number of water curtain tunnels and the distribution of water curtain holes within each geographical boundary. Based on the geographical boundary range, the number of water curtain tunnels, and the distribution of water curtain holes, the water curtain system is divided into multiple non-overlapping primary test zones, and each primary test zone is uniquely identified and numbered.

[0009] In one embodiment, the step of dividing each primary test zone into multiple secondary test zones, using the area enclosed by the water curtain tunnel and the construction tunnel as the boundary, includes: Obtain the water curtain tunnel layout information, construction tunnel layout information, and water curtain hole number-location information for each of the first-level test zones; Based on the water curtain tunnel layout information and the construction tunnel layout information, multiple independent enclosed areas within the first-level test zone are identified. For each enclosed area, all water curtain holes contained within the enclosed area are matched to form a set of water curtain hole groups that correspond one-to-one with the enclosed area; Each enclosed area and its corresponding set of water curtain holes are divided into two-level test zones; Each of the secondary test partitions is hierarchically identified and numbered based on the primary test partition number to form a list of secondary test partition numbers.

[0010] In one embodiment, the step of sequentially conducting an effectiveness test on each of the secondary test zones, including a natural hydrostatic pressure recovery phase, a first hydrodynamic state phase, and a second hydrodynamic state phase, includes: An effectiveness test of the natural hydrostatic pressure recovery phase was conducted on each of the aforementioned secondary test zones; An effectiveness test of the first hydrodynamic state stage was conducted on each of the aforementioned secondary test zones; For each of the secondary test zones, an effectiveness test of the second hydrodynamic state stage is conducted.

[0011] In one embodiment, the step of conducting an effectiveness test on the natural hydrostatic pressure recovery phase for each of the secondary test zones includes: Send a closing command to the valve control device corresponding to all water curtain holes in each of the secondary test zones, so that the valve control device closes the valve of the water curtain hole; When the valve of the water curtain hole is closed, a pressure recording instruction is sent to the pressure monitoring device corresponding to the water curtain hole, so that the pressure monitoring device records the first pressure data of the water curtain hole at a preset recording frequency, and a water level measurement instruction is sent to the water level monitoring device, so that the water level monitoring device measures the first water level data of the water level monitoring hole. When the first pressure data meets the preset stability conditions, pressure recording and water level measurement are stopped, and the effectiveness test of the natural hydrostatic pressure recovery stage is completed.

[0012] In one embodiment, the step of conducting an effectiveness test on each of the secondary test zones in the first hydrodynamic state phase includes: According to the preset hole opening rules, a first group of water curtain holes to be opened and a first group of water curtain holes to be closed are determined from all the water curtain holes in the secondary test zone. When the first group of water curtain holes to be opened is an odd-numbered water curtain hole, the first group of water curtain holes to be closed is an even-numbered water curtain hole. When the first group of water curtain holes to be opened is an even-numbered water curtain hole, the first group of water curtain holes to be closed is an odd-numbered water curtain hole. Send an opening command to the valve control device corresponding to the first group of water curtain holes to be opened, and send a keep-close command to the valve control device corresponding to the first group of water curtain holes to be closed; A pressure recording instruction is sent to the pressure monitoring device corresponding to all the water curtain holes, so that the pressure monitoring device records the second pressure data at a preset recording frequency, and a flow recording instruction is sent to the flow monitoring device corresponding to the first group of water curtain holes to be opened, so that the flow monitoring device records the second flow data at the preset recording frequency. Send a water level measurement command to the water level monitoring device so that the water level monitoring device records the second water level data of the water level monitoring hole at the preset recording frequency; Acquire and parse the second pressure data of the first group of water curtain holes to be closed. If there is a first target water curtain hole with pressure dropping to zero, send a first fine-tuning command to the valve control device corresponding to the first target water curtain hole so that the valve control device adjusts the valve of the first target water curtain hole to a preset water supply pressure and maintains it. When the second pressure data meets the preset stability condition, pressure recording and water level measurement are stopped, and the effectiveness test of the first hydrodynamic state stage is completed.

[0013] In one embodiment, the step of conducting a second hydrodynamic state phase effectiveness test on each of the secondary test zones includes: Switch the first group of water curtain holes to be opened to the second group of water curtain holes to be closed, and switch the first group of water curtain holes to be closed to the second group of water curtain holes to be opened; Send an opening command to the valve control device corresponding to the second group of water curtain holes to be opened, and send a closing command to the valve control device corresponding to the second group of water curtain holes to be closed; A pressure recording instruction is sent to the pressure monitoring device corresponding to all the water curtain holes so that the pressure monitoring device records the third pressure data at the preset recording frequency, and a flow recording instruction is sent to the flow monitoring device corresponding to the second group of water curtain holes to be opened so that the flow monitoring device records the third flow data at the preset recording frequency. Send a continuous water level measurement command to the water level monitoring device so that the water level monitoring device measures the third water level data of the water level monitoring hole at the preset recording frequency; The third pressure data of the second group of water curtain holes to be closed is obtained and analyzed. If there is a second target water curtain hole with pressure dropping to zero, a second fine-tuning command is sent to the valve control device corresponding to the second target water curtain hole so that the valve control device adjusts the valve of the second target water curtain hole to the preset water supply pressure and maintains it. When the third pressure data meets the preset stability condition, pressure recording and water level measurement are stopped, and the effectiveness test of the second hydrodynamic state stage is completed.

[0014] Furthermore, to achieve the above objectives, this application also proposes a zoned test device for the effectiveness of water curtain in underground water-sealed caverns, the device comprising: The primary test zoning module is used to divide the water curtain system into multiple primary test zoning according to the project section; The secondary test zoning module is used to divide each primary test zone into multiple secondary test zones, with the enclosed area of ​​the water curtain tunnel and the construction tunnel as the boundary. The effectiveness test module is used to sequentially perform effectiveness tests on each of the secondary test zones, including a natural hydrostatic pressure recovery phase, a first hydrodynamic state phase, and a second hydrodynamic state phase. The data recording module is used to record the pressure, flow rate, and water level data of each water curtain hole and the water level monitoring hole during the effectiveness test, so as to complete the effectiveness zoning test.

[0015] In addition, to achieve the above objectives, this application also proposes a zoning test device for the effectiveness of water curtain in underground water-sealed caverns. The device includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. The computer program is configured to implement the steps of the zoning test method for the effectiveness of water curtain in underground water-sealed caverns as described above.

[0016] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the zoning test method for the effectiveness of the water curtain in underground water-sealed caverns as described above.

[0017] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the zoning test method for the effectiveness of water curtain in underground water-sealed caverns as described above.

[0018] One or more technical solutions proposed in this application have at least the following technical effects: First, the water curtain system is divided into multiple primary test zones according to the project sections. This initial breakdown of the massive water curtain system based on the construction management interface facilitates organization, coordination, and responsibility allocation. Second, each primary test zone is further divided into multiple secondary test zones, using the enclosed area between the water curtain tunnel and the construction tunnel as the boundary. This ensures that each test unit is relatively independent in terms of space and hydraulics, which is beneficial for precise control and observation. Then, effectiveness tests are conducted sequentially on each secondary test zone, including the natural hydrostatic pressure recovery stage, the first hydrodynamic state stage, and the second hydrodynamic state stage. The hydraulic connectivity and sealing performance are systematically evaluated by closing and alternately opening the water curtain orifices. During the test, the pressure, flow rate, and water level data of each water curtain orifice and the water level monitoring orifice are recorded simultaneously to ensure the completeness and traceability of the data throughout the process. This application, through the combination of two-level zoning and standardized test procedures, can improve the test efficiency and ensure the reliability of test results in the effectiveness test of water curtains in underground water-sealed caverns.

[0022] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0024] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0025] It should be noted that the executing entity of this application embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or water curtain test control system capable of realizing the above functions. The following uses a water curtain test control system as an example to describe this embodiment and the following embodiments.

[0026] Based on this, the embodiments of this application provide a zoning test method for the effectiveness of water curtain in underground water-sealed caverns, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the zoning test method for the effectiveness of water curtain in underground water-sealed caverns according to this application.

[0027] In this embodiment, the method for zoning the effectiveness of the water curtain in the underground water-sealed cavern includes steps S10 to S40: Step S10: Divide the water curtain system into multiple primary test zones according to the project sections.

[0028] It should be noted that a project section refers to the division of the entire underground water-sealed cavern project into several relatively independent construction or management units according to the needs of project construction and management. Each unit is the responsibility of a different construction unit or is advanced according to different time nodes. The water curtain system refers to a water injection structure system arranged above the oil storage cavern, consisting of water curtain tunnels and water curtain orifices, used to maintain a groundwater level higher than the top of the cavern, thereby creating water seal conditions to prevent oil leakage. A primary test zone refers to several large test areas formed by the preliminary division of the entire water curtain system according to the project section when conducting water curtain effectiveness tests. Each area can independently organize test work.

[0029] As an example, the step of dividing the water curtain system into multiple primary test zones according to engineering sections includes: obtaining the engineering section division document of the underground water-sealed cavern and the overall layout information of the water curtain system; clarifying the geographical boundary range of each engineering section according to the engineering section division document; determining the number of water curtain tunnels and the distribution of water curtain holes within each geographical boundary range according to the overall layout information of the water curtain system; dividing the water curtain system into multiple non-overlapping primary test zones according to the geographical boundary range, the number of water curtain tunnels and the distribution of water curtain holes, and assigning a unique identification number to each primary test zone.

[0030] The engineering section division document refers to the formal technical or management document prepared by the engineering construction unit or design unit to clearly define the division of the underground water-sealed cavern project into several sections for construction or management. It specifies the scope of responsibility, construction interface, and spatial boundaries of each section. The overall layout information of the water curtain system refers to comprehensive technical data describing the spatial layout of the entire underground water-sealed cavern water curtain system, including the location, direction, and number of water curtain tunnels, as well as detailed information such as the spacing, length, elevation, and numbering of water curtain holes. The geographical boundary range refers to the actual physical area boundary corresponding to a certain engineering section in the underground space, usually determined by coordinates, tunnel intersection lines, or structural interfaces, used to define the coverage area of ​​the section in three-dimensional space. The number of water curtain tunnels refers to the number of dedicated tunnels for arranging water curtain holes within a certain geographical boundary range. The distribution of water curtain holes refers to the spatial arrangement characteristics of water curtain holes within a specific area, including their numbering sequence along the water curtain tunnels, spacing, borehole length, elevation position, and whether they are arranged continuously.

[0031] First, the water curtain test control system obtains the engineering section division files and overall layout information of the underground water-sealed cavern from the engineering management platform via a data interface. This includes section division drawings and CAD layout drawings of the water curtain system (e.g., section boundary coordinate files and water curtain hole location data tables exported from the BIM system), ensuring that subsequent zoning work is based on accurate engineering foundation data. Second, the water curtain test control system analyzes the boundary coordinate information in the engineering section division files, automatically identifies and establishes a three-dimensional spatial range model for each section, and clarifies the geographical boundary range of each engineering section (e.g., dividing the entire project into three sections: Q, W, and E, each with clear X / Y / Z coordinate boundaries). This ensures that the zoning is consistent with the actual construction management interface, facilitating the division of responsibilities and coordination for subsequent testing work. Then, the water curtain test control system analyzes the overall layout information of the water curtain system, automatically counting the number of water curtain tunnels and the distribution of water curtain holes within each geographical boundary, including the location, spacing, number, and elevation of the water curtain holes (e.g., counting 3 water curtain tunnels and 142 water curtain holes within section Q, with a hole spacing of 5m to 20m). This ensures that the water curtain system in each zone has relatively complete and independent hydraulic characteristics, avoiding hydraulic interference problems caused by improper zoning. Finally, based on the geographical boundary range, the number of water curtain tunnels, and the distribution of water curtain holes, the water curtain test control system uses a spatial partitioning algorithm to divide the water curtain system into multiple non-overlapping primary test zones, and generates a unique identifier for each primary test zone (e.g., dividing section Q into three primary test zones: A, B, and C). This partitioning method ensures that each zone has clear geographical boundaries and a complete water curtain system structure, and significantly improves the efficiency of water curtain effectiveness testing while ensuring the reliability of test results.

[0032] Step S20: Using the area enclosed by the water curtain tunnel and the construction tunnel as the boundary, each primary test zone is divided into multiple secondary test zones.

[0033] It should be noted that a water curtain tunnel refers to an underground tunnel located above an oil storage cavern, specifically designed for drilling water curtain holes. Its primary function is to serve as a carrier for the water curtain holes, forming a stable underground water seal by injecting water into them. A construction tunnel refers to an auxiliary tunnel used for construction access, equipment transportation, and ventilation during the construction of an underground water-sealed cavern. It typically includes main and branch construction tunnels and connecting tunnels, and is not directly used for arranging water curtain holes. An enclosed area refers to a closed or semi-closed geometric area formed by one or more water curtain tunnels and adjacent construction tunnels on a planar surface. Its boundaries are defined by the tunnel centerline or structural outline, and it has a clearly defined spatial range. A secondary test zone refers to several smaller test units further subdivided within the primary test zone based on the enclosed area formed by the water curtain tunnels and construction tunnels. Each unit can independently conduct water curtain effectiveness tests to improve the precision and operational feasibility of the tests.

[0034] As an example, the step of dividing each primary test zone into multiple secondary test zones based on the enclosed area of ​​the water curtain tunnel and the construction tunnel includes: obtaining the layout information of the water curtain tunnel, the layout information of the construction tunnel, and the water curtain hole number-location information within each primary test zone; identifying multiple independent enclosed areas within the primary test zone based on the water curtain tunnel layout information and the construction tunnel layout information; for each enclosed area, matching all water curtain holes contained within the enclosed area to form a set of water curtain hole groups corresponding one-to-one with the enclosed area; dividing each enclosed area and the corresponding set of water curtain hole groups into secondary test zones; and assigning hierarchical identification numbers to each secondary test zone based on the primary test zone number to form a list of secondary test zone numbers.

[0035] Water curtain tunnel layout information refers to data describing the spatial location, orientation, length, cross-sectional dimensions, and interconnections of all water curtain tunnels within the first-level test zone (e.g., a first-level zone contains three water curtain tunnels perpendicular to the oil storage cavern, numbered M1, M2, and M3, with total lengths of 800m, 750m, and 820m respectively). Construction tunnel layout information describes the planar and elevational layout of all construction tunnels within the first-level test zone, including their orientation, connections, and relative positions to the water curtain tunnels (e.g., two construction tunnels, S1 and S2, parallel to the oil storage cavern, used for traffic and equipment transport). Water curtain hole number-location information refers to a data set recording the unique number of each water curtain hole and its specific coordinates or relative position in three-dimensional space (e.g., water curtain hole A①-001 is located 10m from the starting point of water curtain tunnel M1, with an elevation of −45.2m). A water curtain hole group refers to the set of all water curtain holes belonging to the same enclosed area. These holes are spatially surrounded by both the water curtain tunnel and the construction tunnel, possessing clear boundaries and hydraulic independence. A primary test zone number is a unique identifier assigned to a primary test zone (e.g., Zone A, Zone B, Zone C, Zone D), used to distinguish primary zones corresponding to different sections. Hierarchical identification numbering involves embedding the primary test zone number within the secondary test zone number, with an additional sequential number, forming a structured numbering system with hierarchical relationships (e.g., A-1, A-2, A-3 representing three secondary zones under Zone A). A secondary test zone number list is a complete list of numbers generated according to the hierarchical identification numbering rules for all secondary test zones, used for test organization, data archiving, and result analysis (e.g., [A-1, A-2, A-3, B-1, B-2, …, D-6]).

[0036] First, the water curtain test control system retrieves the water curtain tunnel layout information, construction tunnel layout information, and water curtain hole number-location information from the engineering database for each primary test zone, ensuring a clear understanding of the spatial orientation of all relevant tunnels and the precise coordinates of all water curtain holes within that zone. Then, based on the water curtain tunnel layout information and the construction tunnel layout information, the system automatically identifies multiple independent, non-intersecting enclosed areas naturally bounded by these tunnel boundaries on a planar surface. Next, for each enclosed area, the system uses a spatial matching algorithm to extract all water curtain holes located within that area, forming a set of water curtain holes that strictly corresponds to that enclosed area. Subsequently, each enclosed area and its corresponding set of water curtain holes are treated as an independent unit, formally divided into a secondary test zone. Finally, each secondary test zone is hierarchically identified and numbered according to its primary test zone number, and a complete list of secondary test zone numbers is generated for subsequent test task scheduling and data management.

[0037] Step S30: Perform effectiveness tests on each of the secondary test zones, including the natural hydrostatic pressure recovery stage, the first hydrodynamic state stage, and the second hydrodynamic state stage.

[0038] It should be noted that the natural hydrostatic pressure recovery stage refers to the process of closing all valves of the water curtain orifices within the secondary test zone, keeping them in a closed state, and continuously monitoring the pressure changes within each water curtain orifice and the water level in the monitoring well until the system returns to a stable natural hydrostatic pressure state. This stage is used to obtain baseline pressure data under the initial hydrogeological conditions of the test area (e.g., stability is defined as the difference between the maximum and minimum values ​​in five consecutive readings being less than 10% of the final value). The first hydrodynamic state stage refers to the process of intermittently opening the valves of the odd- or even-numbered water curtain orifices within the secondary test zone after the natural hydrostatic pressure recovery is completed, while keeping the remaining water curtain orifices closed, and simultaneously recording the pressure of all water curtain orifices, the flow rate of the opened orifices, and the water level in the monitoring well until the system reaches a new stable state again. This stage is used to disturb the groundwater system and test the hydraulic connectivity between the water curtain orifices. The second hydrodynamic state stage refers to the process after the first hydrodynamic state stage, where the water curtain orifices opened in the previous stage are closed, and the previously closed orifices are opened (i.e., odd and even numbers are reversed). The pressure, flow rate of all open orifices, and water level of the monitored orifices are recorded until the system stabilizes again. This stage further verifies the symmetry and connectivity reliability of the hydraulic response and identifies potential low-permeability or isolated areas. The effectiveness test is a standardized hydrological test procedure conducted to evaluate the sealing performance and hydraulic connectivity of a groundwater-sealed cavern water curtain system. It includes the three consecutive stages mentioned above, and uses pressure, flow rate, and water level response data to comprehensively determine whether the water curtain system meets the water seal safety requirements.

[0039] Understandably, the water curtain test control system performs effectiveness tests sequentially for each secondary test zone: First, it enters the natural hydrostatic pressure recovery phase, closing all valves of the water curtain holes in that secondary test zone, continuously monitoring and recording the pressure and water level of each water curtain hole, collecting data at a frequency of 0min–10min–20min–30min–1h–2h–4h–6h, and then recording every 6 hours until the pressure reaches a stable state (i.e., the difference between the maximum and minimum values ​​in 5 consecutive readings is less than 10% of the final value); then it enters the first hydrodynamic state phase, intermittently opening the valves of the odd- or even-numbered water curtain holes in that zone to inject water, while the remaining water curtain holes... Keep the system closed and simultaneously record the pressure of all water curtain orifices, the flow rate of the open orifices, and the water level of the water level monitoring orifices, at the same frequency as the previous stage, until the system stabilizes again. Then, enter the second hydrodynamic state stage, close the water curtain orifices opened in the previous stage, and open the previously closed water curtain orifices, recording the pressure, flow rate, and water level data at the same frequency, until the system reaches a stable state again. If the pressure of the unreplenished water curtain orifice drops to zero in the second or third stage, fine-tune its valve to maintain a water supply pressure of 0.1 MPa and record the corresponding flow rate. After the three stages are completed, the effectiveness test of this secondary test zone is completed, and then the next secondary test zone is tested in sequence according to the same procedure.

[0040] Step S40: During the effectiveness test, the pressure, flow rate and water level data of each water curtain hole and the water level monitoring hole are recorded to complete the effectiveness zoning test.

[0041] It should be noted that water level monitoring wells are boreholes specifically installed around or at key locations within the underground water-sealed cavern water curtain system to observe changes in groundwater level. These wells do not participate in water injection; they are solely used to monitor groundwater pressure or level response in real time during the experiment, assisting in assessing the hydraulic connectivity and water seal effectiveness between the wells. Water level data refers to the time-series records of groundwater elevation or corresponding hydraulic head values ​​collected through the water level monitoring wells at each stage of the effectiveness test. These data reflect the response characteristics and stability of the groundwater system under experimental disturbances.

[0042] This embodiment provides a zoning test method for the effectiveness of water curtain in underground water-sealed caverns. First, the water curtain system is divided into multiple primary test zones according to engineering sections, allowing for initial decomposition of the large system based on construction management interfaces, facilitating organization, coordination, and responsibility allocation. Second, each primary test zone is further divided into multiple secondary test zones, using the area enclosed by the water curtain tunnel and the construction tunnel as the boundary. This ensures that each test unit is relatively independent spatially and hydraulically, facilitating precise control and observation. Then, effectiveness tests are sequentially conducted on each secondary test zone, including a natural hydrostatic pressure recovery stage, a first hydrodynamic state stage, and a second hydrodynamic state stage. Hydraulic connectivity and sealing performance are systematically evaluated by closing and alternately opening the water curtain orifices. During the test, pressure, flow rate, and water level data from monitoring orifices at each water curtain orifice are recorded simultaneously, ensuring complete and traceable data throughout the process. This embodiment, through the combination of two-level zoning and a standardized test procedure, improves test efficiency and ensures the reliability of test results in the effectiveness testing of water curtain in underground water-sealed caverns.

[0043] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the zoning test method for the effectiveness of water curtain in underground water-sealed caverns according to this application. Step S30 of the zoning test method for the effectiveness of water curtain in underground water-sealed caverns includes steps S31 to S33: Step S31: Conduct an effectiveness test on the natural hydrostatic pressure recovery phase for each of the secondary test zones.

[0044] As an example, the steps of conducting an effectiveness test on the natural hydrostatic pressure recovery phase for each of the secondary test zones include: sending a closing command to the valve control device corresponding to all water curtain orifices in each secondary test zone, so that the valve control device closes the valve of the water curtain orifice; when the valve of the water curtain orifice is closed, sending a pressure recording command to the pressure monitoring device corresponding to the water curtain orifice, so that the pressure monitoring device records the first pressure data of the water curtain orifice at a preset recording frequency, and sending a water level measurement command to the water level monitoring device, so that the water level monitoring device measures the first water level data of the water level monitoring orifice; when the first pressure data meets the preset stability condition, stopping the pressure recording and water level measurement, and completing the effectiveness test on the natural hydrostatic pressure recovery phase.

[0045] The preset recording frequency refers to the time sequence arrangement of data collection by the pressure monitoring device and the water level monitoring device at fixed time intervals during the natural hydrostatic pressure recovery phase. Specifically, starting from the beginning of the test, data is recorded at 0 minutes, 10 minutes, 20 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, and 6 hours, and then continuously every 6 hours until the stability condition is met. The first pressure data refers to the time-series pressure values ​​collected by the pressure monitoring device at each water curtain orifice with the valves closed during the natural hydrostatic pressure recovery phase. This reflects the process of the system recovering from a disturbed state to a natural hydrostatic pressure state. The first water level data refers to the time-series groundwater level data measured by the water level monitoring device at the water level monitoring orifice during the natural hydrostatic pressure recovery phase. This helps determine whether the regional groundwater system has reached a hydrostatic equilibrium state. The preset stability condition refers to the quantitative standard for determining whether the natural hydrostatic pressure recovery phase has ended, i.e., the pressure data shows no continuous upward or downward trend, and the difference between the maximum and minimum values ​​in five consecutive records is less than 10% of the final value in those five records.

[0046] Step S32: Conduct an effectiveness test of the first hydrodynamic state stage for each of the secondary test zones.

[0047] As an example, the step of conducting an effectiveness test on each of the secondary test zones in the first hydrodynamic state stage includes: determining a first group of water curtain holes to be opened and a first group of water curtain holes to be closed from all water curtain holes in the secondary test zone according to a preset orifice opening rule, wherein when the first group of water curtain holes to be opened is an odd-numbered water curtain hole, the first group of water curtain holes to be closed is an even-numbered water curtain hole, and when the first group of water curtain holes to be opened is an even-numbered water curtain hole, the first group of water curtain holes to be closed is an odd-numbered water curtain hole; sending an opening command to the valve control device corresponding to the first group of water curtain holes to be opened, and sending a keep-close command to the valve control device corresponding to the first group of water curtain holes to be closed; sending a pressure recording command to the pressure monitoring device corresponding to all the water curtain holes, so that the pressure monitoring device records the pressure according to the pressure monitoring device. The system records second pressure data at a preset recording frequency and sends a flow recording instruction to the flow monitoring device corresponding to the first group of water curtain orifices to be opened. The flow monitoring device records the second flow data at the preset recording frequency. A water level measurement instruction is sent to the water level monitoring device so that the water level monitoring device records the second water level data of the water level monitoring orifice at the preset recording frequency. The system acquires and parses the second pressure data of the first group of water curtain orifices to be closed. If there is a first target water curtain orifice with pressure dropping to zero, a first fine-tuning instruction is sent to the valve control device corresponding to the first target water curtain orifice so that the valve control device adjusts the valve of the first target water curtain orifice to a preset water supply pressure and maintains it. When the second pressure data meets the preset stability condition, pressure recording and water level measurement are stopped, completing the effectiveness test of the first hydrodynamic state stage.

[0048] The preset orifice opening rule refers to a control strategy that, during the first hydrodynamic state stage, opens or closes or closes or closes or closes all or odd-numbered or even ... The second flow rate data refers to the time-series data of water injection flow recorded by the corresponding flow monitoring device at a preset recording frequency for only the first group of water curtain orifices to be opened during the first hydrodynamic state stage. The second water level data refers to the time-series data of groundwater level measured by the water level monitoring device at a preset recording frequency for the water level monitoring orifices during the first hydrodynamic state stage, used to reflect the regional water level response under experimental disturbance. The first target water curtain orifice refers to a specific water curtain orifice in the first group of water curtain orifices to be closed whose second pressure data shows a pressure drop to zero, indicating the possible existence of hydraulic isolation or low-permeability areas, requiring fine-tuning intervention. The first fine-tuning command is the adjustment command sent by the water curtain test control system to the valve control device corresponding to the orifice when the pressure of the first target water curtain orifice is detected to drop to zero, used to slightly open the originally closed valve to maintain a small amount of water injection at a preset supply pressure. The preset supply pressure is the target supply pressure value set during the fine-tuning operation, specifically 0.1 MPa, used to prevent complete pressure loss of the water curtain orifice while avoiding significant interference with the overall hydrodynamic state.

[0049] Step S33: Conduct an effectiveness test of the second hydrodynamic state stage for each of the secondary test zones.

[0050] As an example, the step of conducting an effectiveness test on the second hydrodynamic state stage for each of the secondary test zones includes: switching the first group of water curtain holes to be opened to the second group of water curtain holes to be closed, and switching the first group of water curtain holes to be closed to the second group of water curtain holes to be opened; sending an opening command to the valve control device corresponding to the second group of water curtain holes to be opened, and sending a closing command to the valve control device corresponding to the second group of water curtain holes to be closed; sending a pressure recording command to the pressure monitoring device corresponding to all the water curtain holes, so that the pressure monitoring device records the third pressure data at the preset recording frequency, and sending a flow recording command to the flow monitoring device corresponding to the second group of water curtain holes to be opened, so that the pressure monitoring device records the third pressure data at the preset recording frequency, and sending a flow recording command to the flow monitoring device corresponding to the second group of water curtain holes to be opened, so that the flow ... The flow monitoring device records the third flow data at the preset recording frequency; a continuous water level measurement command is sent to the water level monitoring device to enable the water level monitoring device to measure the third water level data of the water level monitoring orifice at the preset recording frequency; the third pressure data of the second group of water curtain orifices to be closed is acquired and analyzed; if there is a second target water curtain orifice with pressure dropping to zero, a second fine-tuning command is sent to the valve control device corresponding to the second target water curtain orifice to enable the valve control device to adjust the valve of the second target water curtain orifice to the preset water supply pressure and maintain it; when the third pressure data meets the preset stability condition, pressure recording and water level measurement are stopped, and the effectiveness test of the second hydrodynamic state stage is completed.

[0051] The second group of water curtain orifices to be closed refers to the group of water curtain orifices that were switched to the closed state during the effectiveness test of the second hydrodynamic state phase. These are the same as the first group of water curtain orifices to be opened during the effectiveness test of the first hydrodynamic state phase (for example, if odd-numbered water curtain orifices were opened during the effectiveness test of the first hydrodynamic state phase, then these odd-numbered orifices will be closed during the effectiveness test of the second hydrodynamic state phase, becoming the second group of water curtain orifices to be closed). The third group of water curtain orifices to be opened refers to the group of water curtain orifices that were switched to the open state during the effectiveness test of the second hydrodynamic state phase. These are the same as the first group of water curtain orifices to be closed during the effectiveness test of the first hydrodynamic state phase (for example, if even-numbered water curtain orifices were closed during the effectiveness test of the first hydrodynamic state phase, then these even-numbered orifices will be opened during the effectiveness test of the second hydrodynamic state phase, becoming the second group of water curtain orifices to be opened). The third pressure data refers to the pressure time-series data collected by the pressure monitoring device at a preset recording frequency for all water curtain orifices (including newly opened and newly closed ones) during the second hydrodynamic state phase, used to determine whether the system has reached a stable state again. The third flow rate data refers to the time-series data of the injection flow rate recorded by the corresponding flow monitoring device at a preset recording frequency for the second group of water curtain orifices to be opened during the second hydrodynamic state stage. The third water level data refers to the time-series data of the groundwater level measured by the water level monitoring device at a preset recording frequency during the second hydrodynamic state stage, used to reflect the regional water level response under disturbance during this stage. The second target water curtain orifice refers to a specific water curtain orifice in the second group of water curtain orifices to be closed whose third pressure data shows a pressure drop to zero, indicating potential hydraulic isolation or low permeability issues requiring fine-tuning intervention. The second fine-tuning command refers to the adjustment command sent by the water curtain test control system to the valve control device corresponding to the orifice when the pressure of the second target water curtain orifice is detected to drop to zero, used to slightly open the originally closed valve to maintain a small amount of water injection at a preset supply pressure, preventing complete pressure loss.

[0052] This embodiment first performs an effectiveness test on each secondary test zone during the natural hydrostatic pressure recovery phase, then performs an effectiveness test on the first hydrodynamic state phase, and finally performs an effectiveness test on the second hydrodynamic state phase. This three-stage progressive test process is implemented in an orderly manner based on the zones, which can improve the test efficiency and ensure the reliability of the test results in the effectiveness test of water curtain in underground water-sealed caverns.

[0053] In this embodiment, the water curtain system of the underground water-sealed cavern is as follows: Figure 3 As shown in the figure, this diagram illustrates the layout of a group of caverns and their water curtain system. A typical cavern project consists of three or more groups of caverns, with generally more than five water curtain tunnels and 500 to 1000 water curtain openings. Figure 3 The explanation will be based on a single set of cave jars.

[0054] The water curtain tunnels are located approximately 25 meters above the oil storage caverns and consist of multiple tunnels. Water curtain holes, 50-100 meters long and spaced 5-20 meters apart, are drilled 1-2 meters above the floor of the water curtain tunnels. The water curtain tunnels and water curtain holes together form a water curtain system. During construction and operation, water is injected into the water curtain holes to maintain a relatively stable groundwater level, ensuring the safety of the water seal for oil storage.

[0055] like Figure 3 As shown, two water curtain tunnels are arranged above the cavern. Water curtain tunnel 1 has 19 water curtain holes, numbered A①-001 to 019; water curtain tunnel 2 has 24 water curtain holes, numbered A②-001 to 024.

[0056] Experimental zoning principles and methods: (1) The first step is to divide the entire water curtain system into several areas according to the project section division, namely water curtain system A / B / C / D / E areas, such as Figure 4 As shown; (2) The second step is to divide the water curtain system of each section into several areas, using the area enclosed by the water curtain tunnel and the construction tunnel as the boundary; (3) The third step, such as Figure 5 Taking Zone A of the water curtain system in a project section as an example, the outermost left group of water curtain holes is Zone A-1, the area enclosed by the two adjacent water curtain tunnels is Zone A-2, and the outermost right water curtain hole is Zone A-3. The division principle for the remaining Zones B / C / D / E is similar.

[0057] (4) In the fourth step, during the experiment, effectiveness tests were conducted separately in areas A-1, A-2 and A-3.

[0058] The water curtain effectiveness test consists of the following three consecutive stages: (1) First stage: Natural hydrostatic pressure recovery stage Close all valves of the water curtain orifices in the test area and record the pressure of all water curtain orifices at the following frequency: Record the data for the following periods after the start of the test: 0 min, 10 min, 20 min, 30 min, 1 h, 2 h, 4 h, and 6 h, and then every 6 hours thereafter. Recording should continue until the pressure reaches a stable state, which is defined as a state where the value shows no continuous trend of change, and the difference between the maximum and minimum values ​​in five consecutive readings is less than 10% of the final value.

[0059] The water level in the monitoring well was measured simultaneously during the test.

[0060] (2) Second stage: First hydrodynamic state Open the valves of the water curtain orifices at intervals (numbered either even or odd), while keeping the remaining orifices (odd or even) closed. Record the pressure of all water curtain orifices and the flow rate of the opened orifices. The recording frequency is: This phase begins at 0 min-10 min-20 min-30 min-1 h-2 h-4 h-6 h, and is recorded every 6 hours thereafter, continuing until the pressure stabilizes and a static system is formed, meaning the values ​​show no continuous trend of change, and the difference between the maximum and minimum values ​​in 5 consecutive readings is less than 10% of the final value.

[0061] During the test, the flow rate of the water curtain orifice was recorded simultaneously, and the water level of the water level monitoring orifice was measured.

[0062] (3) Third stage: Second hydrodynamic state Open the water curtain orifice valves that were closed in stage ②, and close the water curtain orifice valves that were opened in stage ②. Record the pressure of all water curtain orifices, record the flow rate of the opened water curtain orifices, and measure the water level at the water level monitoring orifice. The recording time requirements are the same as for stage 2.

[0063] In stages ② and ③ above, if the pressure of the water curtain hole that is not replenished drops to zero, the valve should be finely adjusted to supply water at a pressure of 0.1 MPa, and the flow rate should be measured and recorded.

[0064] In practical applications, the Heilongjiang XAL underground water-sealed cavern project is currently the largest underground water-sealed cavern project under construction in China, with a designed capacity of 6 million m³. The underground works mainly consist of the main cavern (oil storage), water curtain system, process shafts, main and branch construction roadways, connecting roadways, and ventilation shafts.

[0065] The water curtain system consists of water curtain tunnels and a group of water curtain holes. There are a total of 7 water curtain tunnels, 5 of which are perpendicular to the oil storage cavern and used to install water curtain holes, and 2 are parallel to the oil storage cavern and used for traffic passage. They adopt a straight wall arched cross section with dimensions of 7m×5m and a total length of 6185m. The group of water curtain holes is arranged 1.5m above the bottom plate of the water curtain tunnels, with a spacing of 5m to 20m and a length of 48.5m to 100.0m, totaling 719 holes.

[0066] The water curtain system is divided into zones A, B, C, and D based on the project layout and section division. Combined with the boundary layout between the water curtain tunnel and the construction tunnel, the effectiveness testing zones are further divided into 24 zones. After optimization of the testing zones, the completion time for effectiveness testing in each zone was reduced from over 20 days to 7 days, improving testing efficiency by 285%.

[0067] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the zoning test method for the effectiveness of the water curtain in underground water-sealed caverns. Any simple modifications based on this technical concept are within the scope of protection of this application.

The data recording module 40 is used to record the pressure, flow rate and water level data of each water curtain hole and the water level monitoring hole during the effectiveness test, so as to complete the effectiveness zoning test.
