Description

Technical Field

[0001] This application relates to the field of detection technology for oil storage devices, and in particular to an online leakage detection method, device, equipment, and storage medium for oil storage devices. Background Technology

[0002] After oil is extracted from the ground, it needs to be stored in oil storage devices to prevent it from deteriorating or evaporating. As the oil storage devices are used for a long time, leaks may occur. In order to remedy the leaks in a timely manner, online leak detection of the oil storage devices is required.

[0003] Currently, online leak detection for oil storage devices mainly involves detecting the medium inside the device and detecting the external environment. However, detecting the medium inside the device cannot determine the leak location or the distribution of the leaked material. Detecting the external environment requires installing multiple sensors outside the device to determine the leak location based on changes in the surrounding environment. Due to the large surface area of ​​the oil storage device, sensors cannot locate the leak in a timely manner. In other words, neither detecting the medium inside nor detecting the external environment can promptly pinpoint the leak location, thus reducing the efficiency of online leak detection for oil storage devices. Summary of the Invention

[0016] The recorded liquid level is compared with the actual liquid level for judgment;

[0017] If the recorded liquid level is equal to the actual liquid level, the actual gas pressure of the non-oil-storage space in the oil storage device is filtered out from the monitoring data, and the simulated gas pressure is filtered out from the target environment data.

[0018] The actual gas pressure is compared with the simulated gas pressure for judgment;

[0023] Optionally, the detected pressure includes liquid pressure, and the step of performing equalization analysis on the detected pressure to determine the pressure concentration point in the area to be detected includes:

[0024] If the detected pressure is liquid pressure, then the liquid pressure is analyzed in layers to determine the liquid layer pressure of each layer.

[0025] A pressure equalization analysis is performed on each liquid layer to determine the pressure concentration point in the area to be tested.

[0026] Optionally, the step of performing pressure equalization analysis on each of the liquid layers to determine the pressure concentration point in the area to be detected includes:

[0027] Perform a pressure equalization analysis on each liquid layer to determine the pressure virtual line in each liquid layer.

[0028] The distribution of the pressure virtual lines in each layer is analyzed to identify the abnormal virtual lines that point to the same area in each layer.

[0029] Based on the abnormal virtual line, the pressure concentration point in the area to be detected is determined.

[0030] Optionally, the step of simulating the current environment of the oil storage device based on the oil storage log to determine the target environmental data within the oil storage device includes:

[0040] This application provides an online leakage detection method, apparatus, device, and storage medium for an oil storage device. Compared with existing technologies that cannot promptly determine the leakage location of an oil storage device during online leakage detection, thus reducing the efficiency of online leakage detection, this application acquires monitoring data and oil storage logs of the oil storage device; based on the oil storage logs, it simulates the current environment of the oil storage device to determine the target environment data within the oil storage device; wherein, based on the current changes in oil storage within the oil storage device, it updates the oil storage logs used in the simulation process to simulate the real environment during the use of the oil storage device; based on the monitoring data and the target environment data, it performs pressure equalization analysis on the oil storage device to determine the leakage area; and it calls a pre-set detection device outside the oil storage device to detect the leakage in the leakage area and determine the leakage location of the oil storage device.

[0050] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0051] This application provides an online leakage detection method for an oil storage device. In the first embodiment of the online leakage detection method for an oil storage device, refer to... Figure 1 The online leakage detection method for the oil storage device includes:

[0052] Step S10: Obtain the monitoring data of the oil storage device and the oil storage log of the oil storage device;

[0053] Step S20: Based on the oil storage log, simulate the current environment of the oil storage device to determine the target environment data within the oil storage device. Specifically, based on the current changes in oil storage within the oil storage device, update the oil storage log used in the simulation process to simulate the real environment during the use of the oil storage device.

[0054] Step S30: Based on the monitoring data and the target environment data, perform pressure equalization analysis on the oil storage device to determine the leakage area of ​​the oil storage device;

[0055] Step S40: Call the preset detection device outside the oil storage device to perform leakage detection on the leakage area and determine the leakage location of the oil storage device.

[0056] The purpose of this embodiment is to promptly determine the location of leaks in oil storage devices during online leak detection, thereby improving the efficiency of online leak detection for oil storage devices.

[0057] In this embodiment, it should be noted that the online leakage detection method for the oil storage device can be applied to the online leakage detection device for the oil storage device. The online leakage detection device for the oil storage device is subordinate to the online leakage detection equipment for the oil storage device, and the online leakage detection equipment for the oil storage device is part of the online leakage detection system for the oil storage device.

[0058] Reference Figure 2 It should be noted that the online leak detection system for the oil storage device includes the oil storage device, a central controller, and a detection device. The central controller is used to receive monitoring data from the oil storage device and the oil storage logs. It is also used to simulate the current environment of the oil storage device based on the oil inflow and outflow volumes in the oil storage logs to obtain target environment data corresponding to the oil storage logs. Furthermore, it is used to compare the monitoring data with the target environment data to determine the leak area that needs to be detected by the detection device. Finally, it is used to call the detection device to detect the leak area and determine the leak location.

[0059] The target environment data may include the amount of oil stored in the oil storage device obtained from the simulation of the oil storage log, or the theoretical liquid level in the oil storage device obtained from the amount of oil stored, i.e., the recorded liquid level, or the pressure in the oil storage device caused by the current amount of oil stored, etc., without any specific limitation.

[0060] The oil storage device can be an oil storage tank, an oil tanker, or something similar; there are no specific limitations.

[0061] The monitoring data includes at least the actual liquid level and actual pressure inside the oil storage device; the target environment data includes at least the recorded liquid level and simulated pressure corresponding to the oil storage log.

[0062] In this embodiment, the leakage area of ​​the oil storage device is determined by comparing the monitoring data with the target environment data obtained by simulating the oil storage device and performing pressure equalization analysis. That is, firstly, it is determined whether the oil storage device has leaked, and further, the leakage area of ​​the oil storage device is determined by the pressure distribution inside the oil storage device.

[0063] It should be noted that the oil storage log records the normal oil volume entering and exiting the oil storage device, as well as the time of entry and exit. By performing oil storage simulation on the oil storage device using the data in the oil storage log, the recorded liquid level and simulated pressure under normal conditions can be determined. That is, the liquid level and pressure of the oil storage device when no leakage occurs should be the same as the recorded liquid level and simulated pressure in the oil storage log within the allowable error range. If the actual liquid level is lower than the recorded liquid level, it can be determined that the oil storage device is leaking. Since the pressure inside the oil storage device is greater than the pressure outside the oil storage device, the pressure inside the oil storage device will push the stored oil or gas inside the oil storage device outward. By analyzing the pressure distribution, the leakage area of ​​the oil storage device can be determined.

[0064] In this embodiment, by acquiring monitoring data collected by the data acquisition module inside the oil storage device, along with the oil storage log, the oil storage device can be detected online. Based on the pressure distribution inside the oil storage device, the leakage area of ​​the oil storage device can be determined, thereby reducing the area detected by the preset detection device outside the oil storage device. This shortens the inspection time of the detection device, enabling the detection device to detect the specific leakage location on the oil storage device in a timely manner, and improving the efficiency of online detection of the oil storage device.

[0065] In this embodiment, refer to Figure 2 , Figure 2 This is a schematic diagram of the network topology of the online leak detection system for the oil storage device in this application.

[0066] The specific steps are as follows:

[0067] Step S10: Obtain the monitoring data of the oil storage device and the oil storage log of the oil storage device;

[0068] In this embodiment, the environment inside the oil storage device is collected by the data acquisition module in the oil storage device. The data acquisition module can collect at least one of the following: actual liquid level, actual pressure, actual temperature, etc. The data acquisition of different environmental factors can be collected by a comprehensive data acquisition module or by multiple corresponding data acquisition modules to collect data according to different categories.

[0069] The integrated data acquisition module can collect temperature data, liquid level data, and pressure data, among others. The corresponding data acquisition modules are temperature data acquisition modules, liquid level data acquisition modules, and pressure data acquisition modules, which are installed in the oil storage device to collect different data about the oil storage device environment.

[0070] It should be noted that the acquired monitoring data can be data within a specified time interval. In other words, the acquired monitoring data is data within a certain period. When detecting leaks in oil storage devices, the latest data must be used to reduce the error rate. For example, if the preset time interval for acquiring monitoring data is 20 minutes, and the latest acquisition time is 14:00, then the acquired data is from 13:40 to 14:00. The monitoring data at 14:00 needs to be filtered from this data.

[0071] It should be noted that the acquired monitoring data can also be real-time data. That is, ignoring the data transmission time, the time of data acquisition is the same as the time of data reception by the central controller, so as to improve the real-time performance of the oil storage device.

[0072] The oil storage log is stored in the central controller. When the central controller needs to use the oil storage log, it can retrieve the oil storage log by calling the module.

[0073] Step S20: Based on the oil storage log, simulate the current environment of the oil storage device to determine the target environment data within the oil storage device. Specifically, based on the current changes in oil storage within the oil storage device, update the oil storage log used in the simulation process to simulate the real environment during the use of the oil storage device.

[0074] In this embodiment, the central controller first determines the oil storage volume recorded in the oil storage log based on the oil output and oil inflow recorded in the oil storage log. Then, the oil storage volume is input into the simulation module, and the oil storage device is simulated through the simulation module. That is, the oil output and oil inflow of the oil storage device are simulated to determine the recorded liquid level in the oil storage device. The theoretical pressure in the oil storage device at the recorded liquid level is determined through the simulation module.

[0075] In this embodiment, before performing environmental simulation on the oil storage device, a simulation model of the oil storage device needs to be determined. The size, shape, and material of the simulation model need to be the same as the oil storage device, and usage traces are set on the simulation model based on usage data to reduce pressure simulation errors. The simulation model can be a 3D model or a 2D model, etc., and there is no specific limitation.

[0076] Specifically, the step of simulating the current environment of the oil storage device based on the oil storage log to determine the target environmental data within the oil storage device includes:

[0077] Step S21: Query the oil storage log to obtain the oil storage amount corresponding to the oil storage log of the oil storage device;

[0078] Step S22: Using the oil storage volume as a simulation parameter, simulate the current environment of the oil storage device to determine the target environmental data within the oil storage device.

[0079] In this embodiment, the oil storage log is queried, and the data of oil entering and leaving the oil storage device is determined according to the time sequence. Based on the data of oil entering and leaving the oil, the oil storage amount corresponding to the oil storage log of the oil storage device is obtained, that is, the oil storage amount that the oil storage device should have when no leakage occurs.

[0080] In this embodiment, the oil storage device is simulated and analyzed based on the oil storage volume. The recording liquid level of the oil storage device is determined using a preset simulation module, and the pressure within the device at the recorded liquid level (i.e., the simulated pressure) is also determined. The recorded liquid level and simulated pressure are then combined to obtain the target environmental data. In this embodiment, the simulation module can obtain the recorded liquid level and simulated pressure of the oil storage device under normal operating conditions, thus providing a highly reliable judgment condition for leak detection.

[0081] Step S30: Based on the monitoring data and the target environment data, perform pressure equalization analysis on the oil storage device to determine the leakage area of ​​the oil storage device;

[0082] In this embodiment, the actual liquid level in the monitoring data is first compared with the recorded liquid level in the target environment data to determine the size relationship between the actual liquid level and the recorded liquid level. Based on the size relationship, it is determined whether there is a leakage area in the oil storage device.

[0083] The leakage area may include one or more areas corresponding to the oil storage space on the oil storage device, or one or more areas corresponding to the non-oil storage space on the oil storage device.

[0084] It should be noted that by detecting the leakage area corresponding to the non-oil storage space, leakage can be prevented in advance after the actual liquid level in the oil storage device rises.

[0085] Specifically, the step of comparing the monitoring data with the target environmental data and performing pressure equalization analysis on the oil storage device to obtain the leakage area of ​​the oil storage device includes:

[0086] Step S31: Compare and judge the monitoring data with the target environment data to determine the area to be detected of the oil storage device;

[0087] Step S32: Filter out the detection pressure corresponding to the area to be detected from the monitoring data;

[0088] Step S33: Perform a balanced analysis on the detected pressure to determine the leakage area where the pressure is concentrated in the area to be detected.

[0089] The area to be tested is divided into the area corresponding to the oil-stored space within the oil storage device and the area corresponding to the non-oil-stored space.

[0090] The pressure detected may include the actual liquid pressure inside the oil storage device, or the actual gas pressure inside the oil storage device.

[0091] In this embodiment, the actual liquid level is first compared with the recorded liquid level. If the actual liquid level is less than the recorded liquid level and the actual gas pressure is equal to the simulated gas pressure, the area to be detected is determined to be the area corresponding to the oil storage space of the oil storage device. By performing a balance analysis on the liquid pressure, the balance of liquid pressure in the oil storage is determined. From the balance, the pressure concentration area is screened out, and then the leakage area is determined.

[0092] For example, if the actual liquid level extracted from the monitoring data is 65 and the recorded liquid level extracted from the target environment data is 66, it is determined that there is an oil leak in the oil storage device. Then, the area corresponding to the oil storage space of the oil storage device is determined as the area to be detected. The liquid pressure is extracted from the monitoring data and a pressure equalization analysis is performed. Since the pressure inside the oil storage device is greater than the pressure outside the oil storage device, the liquid pressure will be concentrated at the leak location of the oil storage device. By filtering out the area with concentrated pressure from the equalization situation, the leak area can be determined.

[0093] In this embodiment, if the actual liquid level is equal to the recorded liquid level, it is necessary to further determine the actual gas pressure and compare it with the simulated gas pressure obtained based on the oil storage log to determine the relationship between the actual gas pressure and the simulated gas pressure. If the actual gas pressure is less than the simulated gas pressure, the area to be detected is determined to be the area corresponding to the non-oil storage space of the oil storage device. By performing a balance analysis on the actual gas pressure, the balance of the actual gas pressure in the oil storage device is determined. From the balance, the pressure concentration area is screened out, and then the leakage area is determined.

[0094] For example, if the actual liquid level extracted from the monitoring data is 65 and the recorded liquid level extracted from the target environment data is 65, it is determined that there is no oil leakage in the oil storage device. Furthermore, by comparing the actual gas pressure with the simulated gas pressure, it is possible to detect whether there is a leakage area in the area corresponding to the non-oil storage space of the oil storage device. If the actual gas pressure extracted from the monitoring data is 70 and the simulated gas pressure extracted from the target environment data is 72, it is determined that the area corresponding to the non-oil storage space of the oil storage device is the area to be detected. Similarly, by filtering out the areas with concentrated pressure from the equilibrium situation, the leakage area can be determined.

[0095] In this embodiment, if the actual liquid level is lower than the recorded liquid level and the actual gas pressure is lower than the simulated gas pressure, the area to be detected is determined to be the area corresponding to the non-oil-storage space of the oil storage device and the area corresponding to the oil-storage space. That is, the entire oil storage device is to be detected. This requires not only to perform a balance analysis on the actual gas pressure to determine the balance of the actual gas pressure in the oil storage device and to screen out the pressure concentration area from the balance to determine the leakage area, but also to perform a balance analysis on the liquid pressure to determine the balance of the liquid pressure in the oil storage device and to screen out the pressure concentration area from the balance to determine the leakage area.

[0096] Specifically, the step of performing a pressure equalization analysis on the detected pressure to determine the leakage area where the pressure is concentrated in the region to be detected includes:

[0097] S331, Perform a balanced analysis on the detected pressure to determine the pressure concentration point in the area to be detected;

[0098] S332, with the pressure concentration point as the center, determine the fault-tolerant area within a preset area, and define the fault-tolerant area as the leakage area of ​​the area to be detected.

[0099] In this embodiment, since analysis errors may occur when performing equalization analysis on the detected pressure, after determining the pressure concentration point of the area to be detected, the pressure concentration point is used as the center of the preset area to determine the fault tolerance area, and the fault tolerance area is defined as the leakage area, so as to avoid the pressure concentration point not being the leakage location due to analysis errors, which would cause the detection device to detect the wrong location and cause missed detection.

[0100] The preset area is larger than the area of ​​the maximum error range of the equilibrium analysis.

[0101] refer to Figure 4For example, if the pressure concentration point of the oil storage device is determined to be point A through equilibrium analysis, but the actual leakage location of the oil storage device is point B, if point A is directly detected, the result will be that there is no leakage at point A or there is no tendency to leak at point A. However, if a preset area is expanded outward from point A to obtain a fault-tolerant area, that is, a leakage area, point B will be included. If the leakage area is detected, leakage or leakage tendency will be detected at point B, thus avoiding missed detection.

[0102] Step S40: Call the preset detection device outside the oil storage device to perform leakage detection on the leakage area and determine the leakage location of the oil storage device.

[0103] The detection device can detect pressure, temperature, and other parameters.

[0104] It should be noted that multiple detection devices are installed. Since the oil storage device may detect multiple leak areas simultaneously, if only one detection device is installed, only one leak area can be timed, and other leak areas cannot be monitored in a timely manner. If multiple devices are installed, multiple leak areas can be detected simultaneously, improving detection efficiency.

[0105] In this embodiment, after determining the leakage area, the detection device is invoked to detect the leakage area of ​​the oil storage device. This avoids installing a large number of detection devices around the oil storage device, reducing the cost of installing detection devices. It also avoids installing a small number of detection devices to conduct overall detection and investigation of the entire oil storage device, thus improving the efficiency of detection.

[0106] In this embodiment, monitoring data from the oil storage device is acquired by a data acquisition device, and the oil storage log of the oil storage device is obtained. The oil storage volume corresponding to the oil storage log is determined through the oil storage log. The oil storage volume is used as the input for simulation to simulate the oil storage device and determine the target environmental data corresponding to the oil storage device, that is, the environmental data when the oil storage device is not leaking. By comparing the monitoring data and the target environmental data, and performing pressure equalization analysis on the oil storage device, the leakage area is determined. Then, a detection device preset outside the oil storage device is used to detect the leakage area to accurately determine the leakage location of the oil storage device. In this embodiment, determining the leakage area through monitoring data can reduce the number of detection devices, reduce costs, or reduce the inspection area of ​​the detection devices, thus reducing inspection time. Detecting the leakage area through the detection device can accurately locate the leakage location, thereby improving the speed of determining the leakage location and thus improving the online leakage detection rate of the oil storage device.

[0107] This application provides an online leakage detection method, apparatus, device, and storage medium for an oil storage device. Compared with existing technologies that cannot promptly determine the leakage location of an oil storage device during online leakage detection, thus reducing the efficiency of online leakage detection, this application acquires monitoring data and oil storage logs of the oil storage device; based on the oil storage logs, it simulates the current environment of the oil storage device to determine the target environment data within the oil storage device; wherein, based on the current changes in oil storage within the oil storage device, it updates the oil storage logs used in the simulation process to simulate the real environment during the use of the oil storage device; based on the monitoring data and the target environment data, it performs pressure equalization analysis on the oil storage device to determine the leakage area; and it calls a pre-set detection device outside the oil storage device to detect the leakage in the leakage area and determine the leakage location of the oil storage device. In this application, monitoring data and oil storage logs of the oil storage device are obtained, and the oil storage logs are updated in real time according to changes in the oil volume of the oil storage device. Based on the data in the oil storage logs, the current environment of the oil storage device under working conditions is simulated, that is, the simulation includes changes in oil volume, to obtain the target environment data inside the oil storage device that finally corresponds to the oil storage logs. The monitoring data is compared with the target environment data to determine the leakage area of ​​the oil storage device. Then, a pre-set detection device on the outside of the oil storage device is called to detect the leakage area and determine the specific location of the leakage. In other words, in this application, the leakage area of ​​the oil storage device is first determined by monitoring data and real-time updated oil storage logs, and then the detection device on the outside of the oil storage device is called to accurately detect the leakage area to narrow down the detection area of ​​the detection device, thereby determining the leakage location of the oil storage device in real time and improving the efficiency of online leakage detection of the oil storage device.

[0108] Furthermore, based on the above embodiments of this application, another embodiment of this application is provided, in which reference is made to... Figure 5 The step of comparing the monitoring data with the target environmental data to determine the area to be detected of the oil storage device includes:

[0109] Step S010: Filter out the actual liquid level in the oil storage device from the monitoring data, and filter out the recorded liquid level of the oil storage device from the target environment data;

[0110] Step S202: Compare the recorded liquid level with the actual liquid level to determine the liquid level;

[0111] Step S030: If the recorded liquid level is equal to the actual liquid level, then the actual gas pressure of the non-oil-storage space in the oil storage device is filtered out from the monitoring data, and the simulated gas pressure is filtered out from the target environment data.

[0112] Step S040: Compare and determine the actual gas pressure with the simulated gas pressure;

[0113] Step S050: If the actual gas pressure is equal to the simulated gas pressure, then the area corresponding to the oil storage space in the oil storage device is determined as the area to be detected.

[0114] It should be noted that the oil stored in the oil storage device may be of low or high concentration. If the oil storage device stores high-concentration oil, the oil in the storage device will not flow out of the leak hole under the current pressure, and it also prevents the gas in the storage device from flowing out of the leak hole. At this time, the recorded liquid level is equal to the actual liquid level, and the actual gas pressure is equal to the simulated gas pressure. This usually leads to the mistaken conclusion that there is no leak in the oil storage device, resulting in a false detection of the leak location. In this embodiment, when the judgment result is that the recorded liquid level is equal to the actual liquid level, and the actual gas pressure is equal to the simulated gas pressure, the area corresponding to the oil storage space in the oil storage device is determined as the area to be detected. Further detection is performed on this area to detect the leak hole where there is no oil leakage.

[0115] In this embodiment, if a hole appears in the oil storage device, the pressure inside the oil storage device will force the oil inside the oil storage device to flow towards the hole. Even if the pressure cannot force the oil out of the oil storage device, there will be a tendency for pressure concentration at the leak hole. By analyzing the pressure balance, the leak hole of the oil storage device, that is, the leak location, can be determined, thereby avoiding missed detection.

[0116] Furthermore, based on the above embodiments of this application, another embodiment of this application is provided. In this embodiment, the detected pressure includes liquid pressure, and the step of performing equalization analysis on the detected pressure to determine the pressure concentration point in the area to be detected includes:

[0117] Step C10: If the detected pressure is liquid pressure, then perform a layered analysis of the liquid pressure to determine the liquid layer pressure of each layer.

[0118] Step C20: Perform pressure equalization analysis on each liquid layer to determine the pressure concentration point in the area to be detected.

[0119] In this embodiment, since the pressure of the oil stored in the oil storage device comes from the gas and its own gravity, that is, the closer to the bottom of the oil storage device, the greater the pressure of the oil. The liquid pressure can be layered according to the pressure magnitude, the pressure of each liquid layer can be determined, and then the liquid layer pressure can be balanced to determine the trend direction of pressure concentration, and the pressure concentration point can be determined according to the trend direction.

[0120] In this embodiment, by performing a stratified analysis of the liquid pressure, the directional trend of the liquid pressure is refined, so as to more accurately determine the pressure concentration point.

[0121] Specifically, the step of performing pressure equalization analysis on each of the liquid layers to determine the pressure concentration points in the area to be detected includes:

[0122] Step C21: Perform an equalization analysis on the pressure of each liquid layer to determine the pressure virtual line in the pressure of each liquid layer;

[0123] Step C22: Analyze the distribution of the pressure virtual lines in each layer to determine the abnormal virtual lines where the pressure virtual lines in each layer converge.

[0124] Step C23: Based on the abnormal virtual line, determine the pressure concentration point in the area to be detected.

[0125] It should be noted that the pressure virtual line is an analysis line for the directional distribution of pressure.

[0126] In this embodiment, a pressure virtual line is determined for the pressure of each liquid layer, and anomaly virtual lines with concentrated directions are analyzed based on the pressure virtual lines. Based on the directional trend of the anomaly virtual lines, the pressure concentration point of the oil storage device is determined.

[0127] In this embodiment, the pressure virtual line can be transmitted to the user's monitor so that the user can determine the size of the leakage opening based on the concentration of the pressure virtual line.

[0128] In this embodiment, reference Figure 6 By performing stratified analysis of liquid pressure, the directional trend of liquid pressure is refined, and the concentration trend of liquid pressure is intuitively represented by pressure virtual lines. The pressure concentration point can be determined more accurately, and the pressure virtual lines can also be transmitted to the user's monitor, so that the user can judge the size of the leak and prepare repair materials in advance.
