Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage, and in particular to an intelligent monitoring and early warning system for a compressed air energy storage reservoir. Background Art

[0002] Compressed air energy storage is a new energy storage technology that uses compressed air as a medium to store surplus electrical energy. When the power grid is at a low point, new energy sources such as wind and light and excess electricity in the power grid are used to drive compressors to compress air to store electrical energy, and then convert electrical energy into compressed air for storage in rock caves, abandoned salt caverns, abandoned mines or other forms of gas storage. When the power grid is at high load, the high-pressure air in the gas storage is released, and the corresponding potential energy of the compressed air is converted into mechanical energy output of the expander, driving the generator to generate electricity.

[0003] Compressed air energy storage gas storage includes ground gas storage (high-pressure gas tanks and low-temperature storage tanks), rock caves, abandoned salt caverns, waste gas mines, artificial chambers, pipelines and other forms. At present, salt cavern gas storage and artificial chamber gas storage are widely used. Compressed air energy storage power stations generally operate in a high-frequency daily cycle of injection and production, that is, one charge and one discharge per day. When the power station is in operation, the gas storage must withstand a maximum compressed air pressure of 10 to 20 MPa. The gas injection and production wellbore of the gas storage is the only way for the gas storage to inject and produce gas. During the injection and production process of the gas storage, the injection and production wellbore is generally subjected to gas internal pressure, temperature load, viscosity, bulging force, excitation force and other loads. The pressure and temperature in the wellbore change periodically with the alternating cycle of the injection and production process of the gas storage. Its significant characteristics are high operating pressure, high cyclic fatigue loss strength, and high gas sealing requirements. As the construction and operation of this large-scale underground gas storage has just started, there is no mature understanding and method for safety and stability evaluation of the deformation, damage law and structural health of the injection and production wellbore during the filling and release process. Therefore, in order to meet the special operating conditions of high-frequency injection and production, it is necessary to establish a monitoring system for the complete wellbore structure, salt cavity, surface, etc. covered by the gas storage system.

[0036] The embodiment of the present invention provides a possible implementation method, such as Figure 1 As shown, a schematic diagram of the structure of an intelligent monitoring and early warning system for compressed gas energy storage is provided. Figure 1 As shown in , the system may include:

[0037] An injection and production wellbore safety monitoring subsystem and a gas storage reservoir surface displacement monitoring subsystem, wherein the injection and production wellbore safety monitoring subsystem comprises a gas production tree disposed at the wellhead of the injection and production gas well and connected to the injection and production gas well, a gas injection and production wellbore penetrating the interior of the injection and production gas well, an optical fiber disposed on the outer wall of the gas injection and production wellbore, monitoring sensors installed around the injection and production gas wellbore and the gas production tree, and a ground data acquisition device connected to the optical fiber, wherein the monitoring sensor is connected to the optical fiber, and the ground data acquisition device is connected to the data platform in the monitoring room;

[0039] The ground data acquisition equipment is used to collect first monitoring data corresponding to each first monitoring point, and transmit all the first monitoring data to the data platform, so that the data platform can perform safety monitoring and early warning on the gas injection and production wellbore and the gas production tree based on the collected first monitoring data;

[0040] The gas storage reservoir surface displacement monitoring subsystem comprises displacement monitoring stations arranged at each second monitoring point arranged on the surface of the gas storage reservoir, and each of the displacement monitoring stations is connected to the data platform;

[0041] For each of the displacement monitoring stations, the displacement monitoring station is used to obtain the second monitoring data of the corresponding second monitoring point at different times, and transmit the second monitoring data at different times to the data platform, so that the data platform can realize displacement monitoring and early warning of the surface of the gas storage based on the second monitoring data obtained at different times, and the second monitoring data includes location coordinates.

[0042] By respectively acquiring the first monitoring data and the second monitoring data through the injection and production wellbore safety monitoring subsystem and the gas storage reservoir surface displacement monitoring subsystem in the solution of the present application, safety monitoring and early warning of the injection and production wellbore and the gas production tree are implemented based on the first monitoring data, and displacement monitoring and early warning of the gas storage reservoir surface are implemented based on the second monitoring data, thereby realizing all-round monitoring and early warning of the compressed air energy storage reservoir both above and below ground.

[0043] The scheme of the present invention is further described below in conjunction with the following specific embodiments. In this embodiment, a compressed gas energy storage reservoir intelligent monitoring and early warning system is provided, including an injection and production wellbore safety monitoring subsystem and a gas storage reservoir surface displacement monitoring subsystem, the injection and production wellbore safety monitoring subsystem includes a gas production tree arranged at the wellhead of the injection and production gas well and connected to the injection and production gas well, an injection and production gas wellbore running through the inside of the injection and production gas well, an optical fiber arranged on the outer wall of the injection and production gas wellbore, a monitoring sensor installed around the injection and production gas wellbore and the gas production tree, and a ground data acquisition device connected to the optical fiber, the monitoring sensor is connected to the optical fiber, and the ground data acquisition device is connected to the data platform in the monitoring room;

[0044] The monitoring sensor is used to obtain first monitoring data of the gas injection and production wellbore and the gas tree at each first monitoring point;

[0045] The ground data acquisition equipment is used to collect first monitoring data corresponding to each first monitoring point, and transmit all the first monitoring data to the data platform, so that the data platform can perform safety monitoring and early warning on the gas injection and production wellbore and the gas production tree based on the collected first monitoring data;

[0046] The gas storage reservoir surface displacement monitoring subsystem comprises displacement monitoring stations arranged at each second monitoring point arranged on the surface of the gas storage reservoir, and each of the displacement monitoring stations is connected to the data platform;

[0047] For each of the displacement monitoring stations, the displacement monitoring station is used to obtain the second monitoring data of the corresponding second monitoring point at different times, and transmit the second monitoring data at different times to the data platform, so that the data platform can realize displacement monitoring and early warning of the surface of the gas storage based on the second monitoring data obtained at different times, and the second monitoring data includes location coordinates.

[0048] Among them, the full monitoring implementation object of the above-mentioned injection and production wellbore safety monitoring subsystem is the injection and production gas wellbore and the gas production tree, and the monitoring sensors used for monitoring include at least one of the pressure sensor, temperature sensor, flow sensor, acoustic sensor and gas composition detection sensor. Correspondingly, the monitoring data collected by the pressure sensor is pressure, the monitoring data collected by the temperature sensor is temperature, the monitoring data collected by the flow sensor is flow parameter, the monitoring data collected by the acoustic sensor is the vibration parameter, stress strain and leakage parameter of the injection and production gas wellbore, and the monitoring data detected by the gas composition detection sensor is corrosive gas. Correspondingly, the first monitoring data in the present application includes the monitoring data collected by the above-mentioned different types of sensors.

[0049] Among them, the monitoring sensor can be set at each first monitoring point, and the injection and production wellbore safety monitoring system can be composed of a distributed optical fiber temperature monitoring unit (including a temperature sensor distributed at each first monitoring point), a distributed optical fiber acoustic wave monitoring unit (including an acoustic wave sensor distributed at each first monitoring point, which can monitor wellbore vibration, leakage, stress and strain), and a distributed optical fiber pressure monitoring unit (including a pressure sensor distributed at each first monitoring point). Each monitoring unit can be composed of a downhole permanent optical fiber (fixed on the outer wall of the injection and production wellbore, such as Figure 2 As shown in the figure), ground optical fiber data collection equipment, and intelligent monitoring and safety warning system. Among them, the intelligent monitoring and safety warning system is used to perform safety monitoring and warning on the corresponding first monitoring point based on the corresponding collected monitoring data.

[0050] The ground optical fiber data acquisition device in the solution of the present application may include the ground optical fiber data acquisition device corresponding to each of the above-mentioned monitoring units.

[0051] Optionally, the optical fiber is a downhole distributed optical fiber, and the downhole distributed optical fiber is fixed to the outer wall of the gas injection and production wellbore in the form of an optical cable. For details, see Figure 2 The schematic diagram of the permanent optical fiber layout in the gas injection and production well is shown.

[0052] exist Figure 2 In the present invention, the downhole optical cable (also called distributed optical cable) passes through the gas production tree from the wellhead of the injection and production gas well, and is connected to the temperature, vibration, leakage, stress strain and pressure monitoring host (also called data platform) through ground communication optical fiber traction; optionally, the present application scheme can also set up a data collection room (also called ground data collection equipment) at the well site, which can reduce the laying length of the ground optical fiber and make data collection more stable. The first monitoring data and the second monitoring data obtained by monitoring in the present application scheme can also be transmitted to the on-site monitoring room through the cloud platform (wireless transmission) or the communication optical cable laid on the ground (wired transmission). If the 4G or 5G signal of the well site is good, the wireless transmission method of the cloud platform can be used to save costs to the maximum extent.

[0053] In this application scheme, for the intelligent monitoring and early warning system of compressed gas energy storage reservoir, the optical cables involved can be installed in the following ways:

[0054] 1) Optical cable and ground equipment inspection

[0055] Carry out routine inspections on the ground equipment (equipment installed on the ground, such as ground fiber optic data acquisition equipment) to confirm that the ground equipment is working properly, and then perform signal detection on each optical fiber in the optical cable. Only after the inspection is qualified can it be entered into the well.

[0056] 2) Cable tray installation

[0057] Install the cable reel (the cable in a disc shape before it is lowered into the well) on the cable support and prepare the cable for entering the well. The unwinding speed of the cable during the lowering process should be consistent with the speed of the pipe string to avoid stress or relaxation of the cable due to speed inconsistency between the two.

[0058] 3) Installation of wellhead pulley

[0059] The sky pulley is installed on the derrick above the wellhead. During the process of going down the well, the optical cable first passes through the sky pulley and then reaches the wellhead. With the help of the sky pulley, the friction between the optical cable and the wellhead can be reduced, ensuring the curvature radius of the optical cable at the bend.

[0060] 4) Fixation of optical cable and injection and production wellbore

[0061] The underground distributed optical fiber is fixed to the outer wall of the compressed air injection and production wellbore pipe string in the form of an optical cable. During the process of lowering the optical cable into the wellbore, an optical cable coupling protector is installed at each wellbore coupling. The optical cable coupling protector can be made of 304 stainless steel and cast as a whole. Its structural dimensions can be customized according to the dimensions of the injection and production wellbore and its coupling.

[0062] 5) Signal detection during the process of lowering the optical cable into the well

[0063] The optical cable is lowered into the upper wellbore, and a fiber optic signal test is performed on each wellbore to verify the integrity of the optical cable. If any signal detection abnormality occurs midway, the cause is immediately investigated. If the optical cable entering the well is damaged, the optical cable is immediately pulled out to find the damaged point and repair it. If the damaged point cannot be repaired, all the optical cables entering the well are pulled out and new optical cables are lowered again.

[0064] 6) Optical cable crossing oil pipe hanging

[0065] a) Confirm that the instrument signal is normal, leave a 50m margin for the optical cable, and cut the optical cable with a pipe cutter;

[0066] b) Put the penetration sealing assembly used for hanging the oil pipe on the optical cable;

[0067] c) Pass the cut end of the optical cable through the optical cable hole on the oil pipe;

[0068] d) Put the penetration sealing assembly used above the oil pipe on the optical cable;

[0069] e) Tighten the sealing link between the penetration sealing assembly and the oil pipe hanger as well as the sealing link between the penetration sealing assembly and the outer armor of the optical cable to complete the high-pressure seal.

[0070] 7) Fiber-optic well operation

[0071] The lowering of the optical fiber is carried out in the order of lowering the pipe string → connecting the wellbore → installing the coupling protector → connecting the wellbore until the installation of the oil pipe hanging on the last wellbore is completed.

[0072] 8) Optical cable crossing the wellhead

[0073] Pass the optical cable through the side of the special four-way cable. The specific passing position needs to be communicated with the design unit. Use a passing sealing assembly to perform metal high-pressure sealing at the special four-way optical cable passing point.

[0074] 9) Connecting underground optical cable with ground optical cable

[0075] a) After the optical cable passes through the wellhead, the ground end of the downhole optical cable is sealed with high pressure;

[0076] b) Lay the ground acquisition optical cable from the data acquisition room to the wellhead;

[0077] c) Connecting underground optical cables with ground optical cables;

[0078] d) Use splicing boxes to protect the fiber fusion points and cable splicing points;

[0079] e) Bury the underground armored optical cables and ordinary communication optical cables.

[0080] In this application, the pressure sensor is installed as follows:

[0081] 1) Pressure sensor bracket installation

[0082] The pressure sensor is fixed to the outer wall of the injection and production wellbore pipe string through the pressure sensor bracket.

[0083] 2) Connect the pressure sensor to the optical cable

[0084] The pressure sensor and the monitoring optical cable are connected by fusion splicing and protected by a splicing protector.

[0085] In the present application, the principle of the data platform performing safety monitoring and early warning on the injection and production wellbore and the gas tree based on the first monitoring data collected by the injection and production wellbore safety monitoring subsystem is as follows:

[0086] Real-time online monitoring can be carried out for each first monitoring point. Each first monitoring point is located around the gas injection and production wellbore and the gas production tree. Based on the monitoring sensor, the gas injection and production wellbore and the gas production tree can be monitored in real time. For the first monitoring data obtained by monitoring, an early warning can be issued when the first monitoring data is greater than a set threshold. For example, when the first monitoring data is temperature, when the temperature is greater than a preset temperature, a corresponding early warning can be issued, and relevant staff can be notified in time to handle it.

[0087] For each first monitoring point, regular monitoring can also be carried out, that is, for each first monitoring point, regular monitoring of the first monitoring point can be carried out based on multiple first monitoring data obtained within a period of time. Specifically, among the multiple first monitoring data corresponding to the first period of time, if the overall trend is stable, it means that the first monitoring point is safe during this period of time and no early warning is needed. If there is abnormal monitoring data (greater than the set value) among the multiple first monitoring data, it means that the first monitoring point is unsafe during this period of time and may be dangerous. At the same time, an early warning is issued, and relevant staff are notified in time to deal with it.

[0088] In this application, the displacement monitoring station can be a GNSS displacement monitoring station or a Beidou displacement monitoring station. This application does not limit the specific type of positioning technology corresponding to the displacement monitoring station. In this application, for the displacement monitoring station involved in the surface displacement monitoring subsystem of the gas storage reservoir, the installation process is as follows:

[0089] The first step is to install the equipment of the displacement monitoring station

[0090] 1. After the completion of the base, first fix the solar panel on the pole, lead out the power line and mark it, fix the pole on the base, the solar panel is tilted to face due south, the power line of the solar panel is connected to the pole through the buried pipe, and the battery is placed on the pole containing the receiver. The positive and negative poles of the solar panel and the battery should not be connected reversely or incorrectly, and the cross-sectional area of ​​the wire used for connection should not be less than 1.5mm 2 .

[0091] 2. Install the SIM card into the device and organize the wires inside the pole. After the installation is completed, cover the antenna cover and fix it with anti-theft screws. At this time, the displacement monitoring station is installed.

[0092] Step 2: Setting up the second monitoring point

[0093] 1. Arrangement of the location of the second monitoring point

[0094] 1) The arrangement of the second monitoring point corresponding to the salt cavern project should not hinder the normal work of the monitored object and should reduce the adverse impact on the construction work.

[0095] 2) The monitoring signs should be stable, obvious and well-structured. The location of the second monitoring point should avoid obstacles and be easy to observe.

[0096] 3) Principles for selecting the second monitoring point

[0097] The deformation monitoring system (gas storage reservoir surface displacement monitoring subsystem) mainly works with the receivers in the displacement monitoring station, so the site selection must follow the receiver site selection rules and the basic requirements for the receiver station site selection.

[0098] 2. Setting of observation conditions

[0099] The visibility to the sky is good, there should be no large obstacles above 15°, and there should be no metal conductors above 15°. It is convenient for instrument placement and observation operations, away from possible interference sources and away from environments that are prone to multipath.

[0100] 3. Choice of location and facilities

[0101] Good geological conditions, stable points, easy to preserve, taking into account traffic and other conditions as much as possible, making full use of existing observation facilities that meet the requirements, and trying to choose a location where the micro-environment of the station is consistent with the surrounding macro-environment; when selecting a site, it is necessary to conduct data quality analysis on the reference station (the reference station corresponding to the displacement monitoring station) and the second continuous monitoring point, analyze the observation conditions of each second monitoring point, accept the number of observation satellites, position precision factor, etc., and keep records;

[0102] Since we need to install a solar power supply system, we need to ask the locals about the wind and weather conditions at the selected location and keep records. When we survey the selected location, we need to keep detailed records and take photos to facilitate subsequent stone burial and observation.

[0103] 4. Layout of benchmark points

[0104] Combined with the on-site construction environment and the master plan layout, the benchmark point layout should be selected outside the gas storage reservoir settlement influence area. In the surface settlement positioning based on the displacement monitoring station, the benchmark point is set as a stable reference position. Since surface settlement is a relative change process, a fixed and known reference point is required to measure the position changes of other monitoring points. Therefore, the position coordinates of a pre-set benchmark point are considered to be unchanged during the entire monitoring period, or its changes are within a negligible range.

[0105] In the solution of the present application, the second monitoring data includes position coordinates, which may be X-axis coordinates, Y-axis coordinates and Z-axis coordinates respectively.

[0106] For each second monitoring point, real-time online monitoring or periodic monitoring can be performed. The specific implementation process is similar to that of the first monitoring point, and will not be repeated here.

[0107] For a second monitoring point, in the present application scheme, the principle of monitoring and early warning the displacement of the surface of the gas storage reservoir based on the second monitoring data collected at different times by the surface displacement monitoring subsystem of the gas storage reservoir by the data platform is as follows:

[0108] Taking the GNSS displacement monitoring station as an example, the GNSS displacement monitoring station is mainly composed of a GNSS antenna, a solar panel, a main control box (with a main control transmission module inside) and a mounting bracket (station pole), including two parts: a base station and a measuring station. The GNSS displacement monitoring station can upload data to the environmental monitoring platform through the 4G signal network. It is suitable for surface displacement monitoring and building deformation monitoring, such as landslides, slope displacement, bridge deformation, reservoir dams, mining geological disasters, etc.

[0109] Among them, the base station imports known precise coordinates and combines them with the satellite positioning coordinates, calculates the satellite positioning correction data through internal programs, and sends the correction data to each measuring station through LoRa wireless communication. The measuring station uses the satellite positioning coordinates and the obtained base station correction data to upload the corrected data (position coordinates) to the data platform through the network.

[0110] For the location coordinates received by the data platform at the current moment, if the X-axis coordinate and Y-axis coordinate corresponding to the current moment do not shift in the horizontal direction compared with the standard X-axis coordinate and Y-axis coordinate, it means that the surface of the gas storage reservoir has not shifted horizontally; if the Z-axis coordinate corresponding to the current moment does not shift in the vertical direction compared with the standard Z-axis coordinate, it means that the surface of the gas storage reservoir has not shifted in the vertical direction; similarly, if the X-axis coordinate and Y-axis coordinate corresponding to the current moment shift in the horizontal direction compared with the standard X-axis coordinate and Y-axis coordinate, it means that the surface of the gas storage reservoir has shifted horizontally; if the Z-axis coordinate corresponding to the current moment shifts in the vertical direction compared with the standard Z-axis coordinate, it means that the surface of the gas storage reservoir has shifted in the vertical direction, that is, vertical settlement.

[0111] Among them, the standard X-axis coordinate, Y-axis coordinate and Z-axis coordinate may refer to the position coordinates corresponding to when the surface of the gas storage reservoir is not offset, that is, the position coordinates of the reference point determined above.

[0112] In this application, Beidou positioning technology can be used to conduct all-round displacement monitoring of the surface of the gas storage reservoir, and can mainly monitor the settlement and horizontal displacement of the soil at the top of the salt cavern corresponding to the surface of the gas storage reservoir. In order to reduce the impact of on-site construction, solar power supply is selected. The solar power supply duration is long enough for the equipment to work normally in 15 consecutive days of rainy weather. The second monitoring data is uploaded to the data platform through wireless transmission. The data platform can view the second monitoring data in real time. When the second monitoring parameter exceeds the alarm value, the data platform will sound an alarm and notify on-site personnel to check for safety hazards.

[0113] In the present application scheme, the above-mentioned injection and production wellbore safety monitoring subsystem and the gas storage reservoir surface displacement monitoring subsystem can communicate data through the 5G gateway device. Specifically, the monitoring sensor is connected to the network port or Modbus interface, and the compressed gas energy storage reservoir intelligent monitoring and early warning system can be connected to the on-site 5G base station through two 5G SIM cards with fixed IP addresses. The two 5G wireless modules in the compressed gas energy storage reservoir intelligent monitoring and early warning system dial-up to the base station at the same time for hot backup of data. The 5G base station transmits the received data to the data platform and stores it through the database of the data platform. The data generated by the gas storage reservoir surface displacement monitoring subsystem can also be connected to the power station smart site management system. The data generated by the injection and production wellbore safety monitoring subsystem can also be connected to the production control system through the interface station and the one-way isolation network switch, and included in the power station DCS system, thereby realizing the interconnection and interoperability of the data corresponding to the compressed gas energy storage reservoir intelligent monitoring and early warning system with the on-site management platform.

[0114] In the present application, the data platform is also used to monitor the operating status of each link in the injection and production gas production process in the form of a configuration screen.

[0115] Among them, each link refers to each node involved in the gas injection and production process, and each node represents the equipment and process involved in the gas injection and production process. By monitoring the operating status of each link in the gas injection and production process in the form of a configuration screen, abnormal conditions in the gas injection and production process can be discovered in a timely manner.

[0116] Specifically, in the scheme of the present application, devices representing motors, sensors, valves, etc. can be dragged and dropped to the corresponding positions of each device in the gas injection and production process in the production line graphical interface, and the relevant parameters and monitoring data of each device in the gas injection and production process can be displayed to achieve the purpose of monitoring the production process.

[0117] It can be understood that when the data platform monitors the operating status of each link in the gas injection and production process in the form of a configuration screen, it can combine the collected first monitoring data and the second monitoring data. For example, when the safety monitoring and early warning of the gas injection and production wellbore and the gas production tree are carried out based on the collected first monitoring data, and the displacement of the surface of the gas storage reservoir is monitored and warned based on the second monitoring data obtained at different times, each first monitoring data and each second monitoring data involved in the monitoring process, the results of the safety monitoring and early warning of the gas injection and production wellbore and the gas production tree based on the collected first monitoring data, and the results of the monitoring and early warning of the displacement of the surface of the gas storage reservoir based on the second monitoring data obtained at different times can be displayed in the form of a configuration screen.

[0118] Furthermore, in the present application, the system further comprises a video capture device connected to the data platform, the video capture device being used to obtain at least one monitoring screen corresponding to the gas production tree at the ground wellhead, and transmitting at least one monitoring screen to the data platform; the data platform is also used to determine whether the configuration screen corresponding to the same time is consistent with the preset production simulation screen. Figure 1 To.

[0119] Among them, the production simulation diagram is a picture describing the normal production process.

[0120] Optionally, the above information to be displayed, including at least one monitoring screen and a configuration screen, can be displayed in a Web or APP manner.

[0121] Optionally, when the data platform monitors the operating status of each link in the injection and production gas production process in the form of a configuration screen, it can also be combined with the above-mentioned at least one monitoring screen, so that each link in the injection and production gas production process can be monitored more comprehensively.

[0122] Optionally, the production process screen (at least one monitoring screen and a configuration screen) can reflect the characteristics of each production link, and the production process screen can be displayed in various forms such as trend charts, bar charts, and related parameter groups. Among them, for the trend charts and bar charts corresponding to the production process screens, the production process data involved in the injection and production gas production process (including each first monitoring data) can be extracted based on multiple production process screens within a period of time, and the data change trend can be determined based on the production process data to generate a trend chart or a bar chart, so as to reflect the data change trend through the trend chart or bar chart.

[0123] Optionally, in the process of monitoring each link in the injection and production process of gas based on each first monitoring data, each second monitoring data, each monitoring screen and each configuration screen, the data platform can also obtain parameters such as equipment status, alarm status and economic indicators of each equipment involved in the injection and production process based on at least one of each first monitoring data, each second monitoring data, each monitoring screen and each configuration screen, and can also display the real-time values ​​of parameters such as equipment status, alarm status and economic indicators of each equipment in real time.

[0124] Based on the above solution, the data platform can also query the historical trends of each device to understand the parameters such as the device status, alarm status and economic indicators of each device in the historical period based on the historical trends. Among them, the historical trend can be determined based on each first monitoring data, each second monitoring data, each monitoring screen and configuration screen corresponding to the historical period, which can reflect the device status, alarm status and economic indicators of each device in the historical period.

[0125] Based on the above solution, the data platform can also determine the maximum value, minimum value and average value of a certain monitoring data within a period of time based on each first monitoring data and each second monitoring data within the period of time.

[0126] Optionally, the data platform is also used to obtain historical playback data for display based on a user's production process playback request for the injection and production gas well, wherein the production process playback request includes a data identifier of the historical playback data, and the historical playback data includes at least one monitoring screen and a configuration screen.

[0127] The data identifier may be used to indicate which historical time period the historical playback data belongs to, or specifically, which target monitoring point (which may be at least one first monitoring point and / or at least one second monitoring point) corresponds to which historical time period.

[0128] Optionally, the above historical playback data may also include the first monitoring data and / or the second monitoring data corresponding to the data identifier.

[0129] Specifically, in the present application scheme, graphic simulation technology and real-time database technology can be used to conduct an in-depth analysis of the production process to obtain the above-mentioned historical playback data, wherein the graphic simulation technology is used to simulate the first monitoring data and / or the second monitoring data corresponding to the data identifier included in the historical playback data to obtain the corresponding simulation screen for display, and the real-time database technology is used to store the acquired screen in real time so as to provide the user with the historical playback data corresponding to the request when a production process playback request is obtained.

[0130] Furthermore, within the historical data cycle saved in the real-time database, the monitoring screen within any time period can be called up for playback at will. The playback of historical playback data supports multiple fast-forward and slow-forward functions, and supports data playback for any time period, providing a basis for fault and accident reproduction and analysis.

[0131] By querying the historical playback data corresponding to the historical time period based on the production process playback request, the overall operation status of the process flow in the injection and production gas production process can be understood based on the historical playback data. The historical playback data in the application scheme also supports fast display (for example, refreshing 5 minutes of operation status in 1 second) and fast forward when displayed, and can also provide users with settings for data cycle, playback cycle, speed, etc. to meet different playback needs.

[0132] For the historical playback function of the screen corresponding to the historical playback data, you can specify the historical playback data of any time period for playback, which is convenient for reviewing the production operation status. For the playback function, the front-end can use svg and canvas drawing technology to realize the web-side screen display, and support multi-screen synchronous playback at the same time. Specifically, the playback parameters (parameters collected by the system, including but not limited to wellhead gas temperature, annular space temperature, well annular space pressure, etc., also including the first monitoring data and the second monitoring data) are stored in the front-end cache, and each screen is obtained from the front-end cache for synchronous playback, so as to achieve synchronous playback of multiple screens at the same time.

[0133] Furthermore, in the present application scheme, the gas injection and production process can be monitored based on DCS. When displaying historical playback data, the historical playback data can be consistent with the monitoring process of DCS, so that the historical operating conditions (all parameters and states) of the underground gas storage gas production tree and the gas injection and production wellbore gas injection and production can be reproduced more accurately.

[0134] Furthermore, while displaying historical playback data, the currently displayed monitoring screen can also be switched based on the user's screen switching request, and the consistency of parameters can be maintained during the switch. In the process of switching screens, the system can maintain parameter consistency. This means that no matter which monitoring screen the user views, the corresponding parameter values ​​at the same time are the same. As an example, when the user sees the configuration screen of the gas storage injection and production wellbore, and the temperature is A, when switching to the configuration screen corresponding to the gas production tree, the temperature parameter of the gas injection and production wellbore is still displayed as A at the same time. This consistency of parameters ensures that analysts can accurately evaluate the relationship between different systems and the transfer of parameters, and avoid data confusion and misunderstanding caused by screen switching.

[0135] Specifically, the intelligent monitoring and early warning system for compressed gas energy storage reservoirs includes:

[0136] 1. Data acquisition and association

[0137] The data platform extracts historical data (i.e., historical first monitoring data and / or second monitoring data) from the real-time database. These historical data contain various parameters during the operation of the unit, such as time series data of physical quantities such as temperature, pressure, flow, and speed. The sampling period and accuracy of these data are determined according to the system settings and actual needs. For example, temperature data can be sampled once per second, pressure data can be sampled once every 5 seconds, etc.

[0138] At the same time, the intelligent monitoring and early warning system of compressed gas energy storage reservoirs in this scheme can call out monitoring screens that are completely consistent with DCS (gas storage reservoir control system). These monitoring screens are a direct presentation of the actual operating status of the unit, and the monitoring screens include operating status indicator lights of the equipment (such as the start and stop status of the pump, the opening and closing status of the valve, etc.), dynamic display of the process flow and other monitoring screens. By associating the historical data in the intelligent monitoring and early warning system of compressed gas energy storage reservoirs with the corresponding monitoring screens, analysts can clearly see the actual working status of the equipment under specific parameters at a certain moment.

[0139] 2. Recreate historical working conditions

[0140] By using the above-mentioned associated historical data and monitoring screens, the system can reproduce all parameters and states of the unit's historical operating conditions. For example, when analyzing a past main valve failure event, the system can locate the period before the trip and view the changes in parameters such as pressure at that time. At the same time, the operating status of each device associated with the main valve in the monitoring screen can be observed, so as to fully understand the overall operating conditions of the main valve at that time.

[0141] 3. Flexible screen switching

[0142] Users can easily switch screens during playback. These screens cover all aspects of the entire gas storage operation process. For example, when analyzing a fault involving the interaction of multiple systems, users can switch from the injection and production wellbore compression screen to the gas tree screen, and then to the gas storage data access screen, etc., to track the propagation and impact of the fault between different scenarios.

[0143] Optionally, the data platform is further used to display the first target monitoring data based on the first target monitoring data and the pre-established first BIM model, wherein the first target monitoring data includes at least one first monitoring data and a configuration screen corresponding to at least one first monitoring point, and the first BIM model is a model for describing the spatial positions of all first monitoring points corresponding to the injection and production gas wellbore and / or the gas production tree;

[0144] Based on the second target monitoring data and the pre-established second BIM model, the second target monitoring data is displayed, wherein the second target monitoring data includes a configuration screen corresponding to at least one second monitoring data and at least one second monitoring point, and the second BIM model is a model used to describe the spatial positions of all second monitoring points corresponding to the surface of the gas storage reservoir.

[0145] Optionally, when the data platform displays the first target monitoring data based on the first target monitoring data and the pre-established first BIM model, it is specifically used to:

[0146] Displaying the first target monitoring data at a first monitoring point corresponding to the first BIM model;

[0147] When the data platform displays the second target monitoring data based on the second target monitoring data and the pre-established second BIM model, it is specifically used to:

[0148] The second target monitoring data is displayed at a second monitoring point corresponding to the second BIM model.

[0149] In the present application, by finely modeling the gas production trees and injection and production wells corresponding to the gas storage and their respective monitoring points, BIM is deeply integrated with the real-time production situation to achieve real-time display of the injection and production operating data, which is associated with the alarm data. This allows for rapid and accurate positioning of the alarm site, improving on-site operation control efficiency.

[0150] Optionally, the data platform is also used to provide a trend analysis function, specifically:

[0151] Acquire a data query request from a user for a target monitoring point, where the target monitoring point includes at least one first monitoring point and / or at least one second monitoring point;

[0152] Based on the data query request, obtaining target monitoring data of the target monitoring point within a time interval;

[0153] Based on the target monitoring data within the time interval, display the data corresponding to the data query request; and / or, generate and display a trend analysis curve based on the target monitoring data within the time interval.

[0154] In the present application, a Web-based visual analysis tool can be used to provide accurate and timely production process information (target monitoring data). The software provides two configuration methods. For general users, the trend analysis curve is displayed by customizing a combination of measurement points (target monitoring points, including at least two monitoring points) to assist in analysis; for advanced users, the target monitoring points can be selected at will through client configuration to automatically generate the required trend analysis curve, so as to enter into an in-depth and intuitive trend analysis.

[0155] Trend analysis includes two major functions: historical data query and historical curve query. Among them, historical data query specifically refers to: querying the target monitoring data of the target monitoring point within the time interval. Specifically, according to the time interval (custom) or collection cycle (seconds, minutes, hours), combined with the set summary method (average, variance, range, maximum, minimum), obtain the target monitoring data corresponding to the target monitoring point to be queried for query and display, and can support export.

[0156] The present application scheme also supports the comparison of monitoring data from multiple monitoring points, that is, the target monitoring points to be queried are at least two monitoring points. After obtaining the target monitoring data corresponding to each monitoring point based on the above method, the target monitoring data corresponding to at least two monitoring points are compared and displayed.

[0157] Historical curve query specifically refers to: querying the target monitoring data within the time interval to generate a trend analysis curve. Specifically, the historical data (target monitoring data) of a single or multiple measuring points (target monitoring points) within a period of time (time interval) can be plotted into a historical curve (trend analysis curve), through which the historical change trend of the corresponding target monitoring data can be intuitively understood; when drawing the curve, the corresponding target monitoring data can be sampled in a dynamic period when the data volume is large. When multiple trend analysis curves are drawn at the same time, the method of merging coordinate axes can be used so that data with different change ranges can best reflect the change trend.

[0158] In the present application, for any of the above trend analysis curves, the user is also provided with functions such as curve area zooming in, zooming out, curve printing, style configuration, etc. to meet the different needs of users.

[0159] Optionally, the relevant data involved in the intelligent monitoring and early warning system for compressed air energy storage gas storage reservoirs in the present application scheme can be connected to the production control system (third-party system). The intelligent monitoring and early warning system for compressed air energy storage gas storage reservoirs is connected to the data of the production control system, collects data with the help of the real-time data protocol interface, and isolates the data through the isolation network switch. The relevant data involved in the intelligent monitoring and early warning system for compressed air energy storage gas storage reservoirs adopts one-way transmission to ensure that the safe zone 1 in the production control system can control the stable operation of the system, realize real-time data collection and storage of the gas storage reservoir production process, and the data is stored in the safe zone 2 in the production control system, and the data is synchronized again through the isolation network switch to the mirror database of the safe zone 3 in the production control system, and data is exchanged with each other at the application layer of the safe zone 3.

[0160] Optionally, the data platform is further used to analyze the first monitoring data corresponding to each of the first monitoring points at different times and / or the second monitoring data at different times, generate a comprehensive report, and provide the comprehensive report to the user.

[0161] In the present application scheme, a complete, flexible, and visual comprehensive report configuration platform can also be provided. Based on this platform, the first monitoring data corresponding to each of the first monitoring points at different times and / or the second monitoring data at different times can be comprehensively processed and statistically analyzed. Data combination and calculation can be conveniently performed to generate reports to form unit or whole plant production and operation reports (collectively referred to as comprehensive reports). The comprehensive reports can also be converted into Excel format for display and printing, and can also be published via the WEB for query.

[0162] Optionally, the data platform is further used to generate a first alarm message when an abnormality is detected in the gas injection and production wellbore and / or the gas production tree, and to generate a second alarm message when an abnormality is detected in the displacement of the surface of the gas storage.

[0163] Specifically, in the present application scheme, early warning rules are set for the important parameters of each equipment involved in the gas injection and production process (which can be determined based on the first monitoring data and / or the second monitoring data). Through this scheme, the change trend of each important parameter can be monitored dynamically in real time, and the historical data corresponding to each important parameter under the same working conditions can be compared. Once the early warning rule is triggered, the early warning information will be pushed to the specific user to remind the user to check and process it in time to provide support for eliminating the fault. The user finally confirms or cancels the alarm and fills in the measures and processing results for eliminating the fault. The system will automatically record and incorporate it into the knowledge base.

[0164] In the present application scheme, a management function for production accidents, equipment failures, parameter exceeding limits and other emergency events occurring during the gas injection and production process can also be provided. By using this management function, events / alarms can be defined and set, that is, the definition and setting of conditions for determining whether an abnormality occurs in the gas injection and production wellbore and / or the gas production tree, and the definition and setting of conditions for determining whether an abnormality occurs in the displacement of the surface of the gas storage reservoir. When accidents and emergencies occur during the gas injection and production process, an alarm prompt can be quickly issued based on the first alarm information and / or the second alarm information.

[0165] The data platform can also provide query and statistical analysis functions for historical events (events corresponding to the first alarm information and / or the second alarm information).

[0166] Through the scheme of the present invention, a full-space, all-round, three-dimensional monitoring system can be designed for the underground salt cavern gas storage of the compressed gas energy storage power station based on various monitoring means such as Beidou, optical fiber sensing, and instruments.

[0167] Furthermore, the present application may also include the following solutions:

[0168] Each first monitoring point and each second monitoring point are displayed in the form of a BIM model, each first monitoring point corresponds to a first mark, each second monitoring point corresponds to a second mark, and when an abnormality occurs at one or several monitoring points and an early warning is required, the target mark corresponding to the abnormal monitoring point can be displayed at the corresponding position of the BIM model to more clearly indicate the location of the abnormal monitoring point. The target mark can be at least one first mark and / or at least one second mark.

[0169] In the present application scheme, when displaying the target mark corresponding to the monitoring point where the abnormality occurs, if there are many target marks to be displayed, in order to display the target marks more clearly, the following scheme is also proposed:

[0170] A control instruction for scaling the BIM model is generated according to the user's scaling operation on the display screen; in response to the control instruction, a focus position indicated by the user on the display screen is obtained; it is determined whether the focus position belongs to a first mark range of the display mark; when the focus position belongs to the first mark range, a target display mark is searched from the display mark; the BIM model is scaled according to the position information of the found target display mark to display the target mark more clearly, and the BIM model is adaptively scaled according to the position information of the target display mark corresponding to the actual target, thereby overcoming the deviation problem caused by scaling based on the focus position in the prior art, and the user's viewing experience is better.

[0171] The above description is only a preferred embodiment of the present invention and an explanation of the technical principles used. Those skilled in the art should understand that the disclosure scope involved in the present invention is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above disclosed concept.
