[0002] The gas storage column system occupies a vital position in the field of natural gas storage and transportation, and the energy storage reservoir is responsible for peaking the power system through compressed air energy storage, and is a key component of the energy supply chain. At the same time, the safety of the column system has always been a concern. The column may be affected by many factors, including chemical corrosion, erosion, temperature and pressure fluctuations, etc. If the column fails or leaks, it may not only pose a threat to the environment and public safety, but also cause production interruptions and economic losses. Since hidden safety issues such as corrosion and erosion of the column often occur inside the column or in corrosion locations that are not easily detected, it is necessary to monitor the safety of this safety issue. Traditional column safety monitoring methods are often based on empirical models and rules, but empirical models and rules are difficult to adapt to changes in different column conditions and environments, and their monitoring accuracy and applicability are low.

[0003] In the prior art, the pipe string safety monitoring method mainly relies on regular inspections and discrete data collection. Regular inspections and manual data collection require a lot of manpower and time resources, resulting in high operating costs.

The terminal device is used to execute the steps of a pipe string safety management method.

[0025] See also Figure 1 , Figure 1 A flow chart of a safety management method for a pipe string is provided for this application, such as Figure 1 As shown, the present application provides a safety management method for a pipe string, comprising:

[0030] A safety management method for a pipe string in this embodiment determines a safety monitoring strategy through the safety management type of the pipe string to be tested, monitors the sensor data matching the safety monitoring strategy in real time, and obtains monitoring results, so that the safety status of the pipe string to be tested can be monitored in real time, and safety problems existing in the pipe string can be detected in time. Then, safety management measures for the pipe string to be tested are obtained based on the safety management type and the detection results, so that the safety management measures are used to perform safety management on the pipe string to be tested, and timely identification and response to safety problems existing in the pipe string can be achieved, thereby improving the safety of managing the pipe string. The method of the present application realizes automatic monitoring and management of pipe string safety issues without using a large amount of manpower and time resources, so the method of the present application reduces the operating costs of manpower and time.

[0031] Among them, the safety management types include pipeline corrosion and pipeline erosion. Therefore, the specific steps for determining the safety monitoring strategy based on the safety management type may include:

[0032] When the safety management type is pipeline corrosion, the safety monitoring strategy is determined to be the corrosion monitoring strategy;

[0033] When the safety management type is pipeline erosion, the safety monitoring strategy is determined to be the erosion monitoring strategy.

[0034] Optionally, real-time monitoring of sensor data matching the security monitoring strategy is performed, and detection results are obtained based on the sensor data using the security monitoring strategy, including:

[0035] When the safety management type is pipeline corrosion and the corresponding safety monitoring strategy is the corrosion monitoring strategy, the pressure sensor is used to obtain the operating pressure of the pipe string at the corroded part of the pipe string to be tested in real time;

[0036] Obtaining the pipe string information of the pipe string to be tested and the corrosion information of the corroded part, and obtaining the target residual strength of the pipe string to be tested based on the pipe string information and the corrosion information;

[0037] The test result of the pipe string to be tested is determined based on the pipe string operating pressure and the target residual strength.

[0038] In this embodiment, based on the operating pressure of the pipe string and the target residual strength, the test result of the pipe string to be tested is determined, including:

[0039] Determine the pressure ratio based on the string operating pressure and target residual strength;

[0040] The pressure ratio is calculated as:

[0041] K=P / P f ;

[0042] Where K represents the pressure ratio, which is dimensionless, and P represents the operating pressure of the string. f Indicates the target's remaining strength;

[0043] When the pressure ratio is greater than 1, it is determined that the test result of the tested pipe string is in a stable and safe state;

[0044] When the pressure ratio is equal to 1, it is determined that the test result of the tested string is in an unstable safety state;

[0045] When the pressure ratio is less than 1, it is determined that the test result of the tested tubing string is in an unsafe state.

[0046] In this embodiment, when the pipe string to be tested is corroded, the pipe strength of the pipe string to be tested will be reduced. Therefore, the pipe string information of the pipe string to be tested and the corrosion information of the corroded part can be used to understand the pipe strength of the corroded part of the pipe string to be tested, thereby obtaining the pipe strength of the corroded part, which is the target residual strength of the pipe string to be tested. Since the pipe strength of the corroded part is lower than the pipe strength of the uncorroded part, when the safety management type is pipeline corrosion, the corresponding safety monitoring strategy is the corrosion monitoring strategy. At this time, using the pipe string operating pressure and the target residual strength of the corroded part of the pipe string to be tested, it can be understood whether the pipe string to be tested under the target residual strength can withstand the pipe string operating pressure at this time, and the detection result of the safety status corresponding to the pipe string to be tested is obtained. That is, when the pressure ratio is greater than 1, it means that the time that the tested string under the target residual strength can withstand the operating pressure of the string is greater than or equal to the preset time, and the detection result of the tested string is a stable and safe state; when the pressure ratio is equal to 1, it means that the time that the tested string under the target residual strength can withstand the operating pressure of the string is less than the preset time, and the detection result of the tested string is an unstable and safe state; when the pressure ratio is less than 1, it means that the tested string under the target residual strength cannot withstand the operating pressure of the string, and the detection result of the tested string is an unsafe state. The subsequent safety management of the tested string according to the specific safety status can improve the safety of the management process of the tested string.

[0047] Optionally, a pressure sensor is used to obtain the operating pressure of the pipe string at the corroded part of the pipe string to be tested in real time, including:

[0048] Obtain the pipe material type of the pipe string to be tested, and determine the corrosion detection technology for the pipe string to be tested based on the pipe material type;

[0049] The pipe to be tested is tested based on the corrosion detection technology to obtain the corrosion position of the corroded part in the pipe to be tested;

[0050] The pressure sensor is used to detect the pressure at the corrosion position in real time to obtain the operating pressure of the pipe string.

[0051] In this embodiment, the corrosion detection technology for the pipe string to be tested is determined based on the pipe material type of the pipe string to be tested, and the pipe string to be tested is tested based on the corrosion detection technology, so that the pipe string to be tested can be tested in a targeted manner, thereby avoiding the detection error caused by material differences and improving the accuracy of the corrosion position of the corroded part of the pipe string to be tested. A plurality of pressure sensors are installed in sequence from top to bottom in the pipe string to be tested, and the pressure sensor at the corrosion position is used to perform pressure detection, so that the operating pressure of the pipe string at the corroded part of the pipe string to be tested can be obtained in a targeted manner, thereby improving the accuracy of the operating pressure of the pipe string, and further improving the accuracy of the subsequent detection results of the pipe string to be tested obtained by using the operating pressure of the pipe string and the target residual strength.

[0052] In this embodiment, the pipe material categories include ferromagnetic materials and non-ferromagnetic materials; the corrosion detection technology for the pipe string to be tested is determined based on the pipe material category, including:

[0053] When the pipe material is ferromagnetic material, the corrosion detection technology for the pipe to be tested is determined to be eddy current detection technology;

[0054] When the pipe material type is non-ferromagnetic material, it is determined that the corrosion detection technology for the pipe string to be tested is the ultrasonic detection technology.

[0055] In this embodiment, if the pipe to be tested is tested based on the corrosion detection technology and no corrosion position is detected in the pipe to be tested, it means that the pipe to be tested is not corroded, and the sensor data matching the safety monitoring strategy is continuously monitored in real time.

[0056] Optionally, the corrosion information includes corrosion length and corrosion depth; obtaining a target residual strength of the pipe string to be tested based on the pipe string information and the corrosion information includes:

[0057] Determine the expansion coefficient corresponding to the corroded part based on the corrosion length and the pipe string information, and obtain the first pipe string residual strength of the pipe string to be tested based on the pipe string information, the expansion coefficient and the corrosion depth; wherein the pipe string information includes the outer diameter, wall thickness, flow stress and yield strength of the pipe string to be tested;

[0058] The calculation formula for the residual strength of the first pipe string is as follows:

[0059] when hour,

[0060]

[0061] when hour,

[0062]

[0063] σ f =σ s +69.85(MPa),

[0064]

[0065] Where, L represents the corrosion length in mm, D represents the outer diameter of the pipe to be tested in mm, t represents the wall thickness of the pipe to be tested in mm, M represents the Folias expansion coefficient in dimensionless units, P f1 It represents the residual strength of the first pipe string in MPa, a represents the corrosion depth in mm, σ f Represents the flow stress of the pipe string to be tested, σ s Indicates the yield strength of the pipe string to be tested, in MPa;

[0066] Determine the length coefficient corresponding to the corroded part based on the corrosion length and the pipe string information, and obtain the second pipe string residual strength of the pipe string to be tested based on the length coefficient, the pipe string information and the corrosion depth; wherein the pipe string information includes the outer diameter, wall thickness, flow stress and tensile strength of the pipe string to be tested;

[0067] The calculation formula for the residual strength of the second string is as follows:

[0068]

[0069] Where, Q represents the length coefficient, L represents the corrosion length, in mm, D represents the outer diameter of the pipe to be tested, in mm, t represents the wall thickness of the pipe to be tested, in mm, P f2 represents the residual strength of the second string, σ f Represents the flow stress of the pipe string to be tested, σ f =σ b , σ b It represents the tensile strength in MPa, and a represents the corrosion depth in mm;

[0070] Obtaining an average value of the radius between the inner radius and the outer radius included in the pipe string information, and obtaining a third pipe string residual strength of the pipe string to be tested based on the average value of the radius, the corrosion length, the corrosion depth and the pipe string information; wherein the pipe string information includes the flow stress, tensile strength, outer diameter, wall thickness, inner radius and outer radius of the pipe string to be tested;

[0071] The calculation formula for the residual strength of the third pipe string is as follows:

[0072]

[0073] Among them, P f3 represents the residual strength of the third string, σ f Represents the flow stress of the pipe string to be tested, σ f =σ b , σ b Indicates tensile strength, in MPa, D indicates the outer diameter of the pipe to be tested, in mm, t indicates the wall thickness of the pipe to be tested, in mm, a indicates corrosion depth, in mm, L indicates corrosion length, in mm, and R is the average radius between the inner radius and the outer radius of the pipe to be tested, in mm;

[0074] Based on the residual strength of the first pipe string, the residual strength of the second pipe string and the residual strength of the third pipe string, a target residual strength of the pipe string to be tested is obtained.

[0075] In this embodiment, different parameters are used to calculate the residual strength of the test string from different angles to obtain the residual strength of the first string, the residual strength of the second string and the residual strength of the third string, and multiple linear regression is performed based on the residual strength of the first string, the residual strength of the second string and the residual strength of the third string, so that the optimal combination of multiple independent variables is used to jointly predict or estimate the dependent variable to obtain the target residual strength. Compared with the method of predicting the test results by using the residual strength calculated from only one angle, the method of the present application takes into account the influence of parameters at multiple angles on the target residual strength, improves the accuracy of the target residual strength obtained by linear regression, and thus can improve the accuracy of the test results obtained by subsequent predictions.

[0076] Optionally, the detection result includes a stable safety state, an unstable safety state, and an unsafe state;

[0077] Based on the safety management type and test results, determine the safety management measures for the tested pipe string, including:

[0078] When the safety management type is pipeline corrosion and the detection result is a stable and safe state, the sensor data matching the corrosion monitoring strategy corresponding to the pipeline corrosion is continuously monitored in real time;

[0079] When the safety management type is pipeline corrosion and the detection result is an unstable safety state, the injection and production volume of the test string is reduced so that the test string can be injected and produced based on the reduced injection and production volume, and the sensor data matching the corrosion monitoring strategy corresponding to the pipeline corrosion is continuously monitored in real time;

[0080] When the safety management type is pipeline corrosion and the detection result is an unsafe state, a first alarm message is sent to the terminal device, and a first repair strategy for the pipe string to be tested is determined based on the detection result.

[0081] In this embodiment, when the safety management type is pipeline corrosion and the detection result is a stable and safe state, it means that the corrosion of the pipeline in the test string will not affect the use of the test string. At this time, it is only necessary to continue to monitor the test string in real time, so as to understand the corrosion of the pipeline in the test string at any time. When the safety management type is pipeline corrosion and the detection result is an unstable and safe state, it means that the corrosion of the pipeline in the test string will have a slight impact on the use of the test string. At this time, it is only necessary to reduce the injection and production volume of the test string. As long as the test string is injected and produced based on the reduced injection and production volume, it will not affect the use of the test string. At the same time, the test string continues to be monitored in real time, so as to understand the corrosion of the pipeline in the test string at any time. When the safety management type is pipeline corrosion and the detection result is an unsafe state, it means that the pipe string to be tested cannot be used normally at this time. In this case, a first alarm message is sent to the terminal device, so that the staff can promptly understand the unsafe state of the pipe string to be tested and respond to the unsafe state in time. Based on the detection result, a first repair strategy for the pipe string to be tested is determined, and the pipe string to be tested is repaired based on the first repair strategy, thereby realizing the safety management of the pipe string to be tested and improving the safety of the management process of the pipe string to be tested.

[0082] In this embodiment, when the detection result is an unsafe state, the specific steps of determining the first repair strategy of the tested pipe string based on the detection result may include:

[0083] Determine the repair value of the tested pipe string based on the unsafe state and determine the rescue well strategy;

[0084] The first repair strategy is determined based on the repair value and the rescue well strategy.

[0085] Among them, the rescue well strategy is to drill a rescue well for the pipe to be tested; if the repair value is greater than or equal to the preset value, it means that the corrosion of the pipe to be tested can still be repaired and used normally, then a rescue well is drilled next to the pipe to be tested, and the well is entered to use at least one repair technology of anti-corrosion coating, corrosion inhibitor, plating technology, and cathodic protection to repair the pipe to be tested, and the pipe to be tested is continuously monitored in real time to facilitate the understanding of the pipeline corrosion situation in the pipe to be tested at any time; if the repair value is less than the preset value, it means that the corrosion in the pipe to be tested can no longer be repaired to a state where it can be used normally, then the currently corroded pipe to be tested is discarded, and the parameters of the new pipe are determined based on factors such as material, pipe diameter, steel grade, wall thickness, inner diameter, and line weight, a rescue well is drilled next to the pipe to be tested, and the well is entered to replace the pipe to be tested with the new pipe, and the new pipe is continuously monitored in real time to facilitate the understanding of the pipeline corrosion situation in the new pipe.

[0086] Optionally, real-time monitoring of sensor data matching the security monitoring strategy is performed, and detection results are obtained based on the sensor data using the security monitoring strategy, including:

[0087] When the safety management type is pipeline erosion and the corresponding safety monitoring strategy is the erosion monitoring strategy, the sensor group is used to collect the flow pressure, erosion flow rate and erosion flow rate of the wellhead of the well where the pipe string to be tested is located in real time;

[0088] Based on the flow pressure, erosion flow rate and erosion flow velocity, the real diameter of the pipe string to be tested is obtained;

[0089] The true diameter is calculated as follows:

[0090]

[0091] Among them, v e Indicates the erosion velocity in m / s, q e Indicates the erosion flow rate, the unit is 10 4 m3 / d; d represents the inner diameter of the pipe to be tested, in mm;

[0092] Obtain the equivalent diameter of the pipe string to be tested;

[0093] The calculation formula of equivalent diameter is as follows:

[0094]

[0095] Among them, d s It represents the equivalent diameter of the annular space between the tested pipe string and the corresponding casing, in mm. D represents the inner diameter of the casing, in mm. 1 Indicates the outer diameter of the pipe to be tested, in mm;

[0096] The test results are obtained based on the equivalent diameter and the true diameter.

[0097] In this embodiment, based on the equivalent diameter and the true diameter, the specific steps of obtaining the detection result may include:

[0098] Calculate the difference between the equivalent diameter and the true diameter;

[0099] When the difference is not 0, it is determined that the detection result is that erosion occurs;

[0100] When the difference is 0, it is determined that the detection result is that no erosion occurs.

[0101] In this embodiment, since pipeline erosion is likely to occur at the wellhead and bottom of the well where the tested pipe string is located during the injection and production process, and the air flow flows from the bottom of the well to the wellhead, the flow pressure at the wellhead is smaller than the flow pressure at the bottom of the well, while the flow velocity is increasing. Therefore, as long as the erosion flow velocity at the wellhead can meet the condition of no obvious erosion, the erosion flow velocity at any section of the tested pipe string will also be able to meet this condition. At the same time, since the equivalent diameter of the tested pipe string increases after the pipe erosion occurs in the tested pipe string, when the tested pipe string is injected and produced, the actual diameter of the tested pipe string calculated based on the flow pressure, erosion flow rate and erosion flow rate at the wellhead of the well where the tested pipe string is located collected by the sensor group is compared with the equivalent diameter when the tested pipe string has not been eroded, so that it can be understood whether the tested pipe string has undergone pipe erosion, that is, when the difference between the equivalent diameter and the actual diameter is not 0, it indicates that the tested pipe string has undergone pipe erosion, that is, the detection result is that erosion has occurred, and when the difference between the equivalent diameter and the actual diameter is 0, it indicates that the tested pipe string has not undergone pipe erosion, that is, the detection result is that erosion has occurred. Safety management of the tested pipe string based on the detection result can improve the safety of the management process of the tested pipe string.

[0102] In some embodiments of the present application, the flow pressure, erosion flow rate and erosion flow rate of the wellhead of the well where the pipe string to be tested is located can be simulated by CFD simulation or erosion calculation mathematical model to simulate the simulation model of the pipe string to be tested. The simulation model consists of g The calculation formula Substitute v e The calculation formula where v e is the erosion velocity, m / s; ρ g is the gas density, kg / m3; γ g is the relative density of gas; p is the oil (casing) pipe flow pressure, MPa; Z is the gas deviation coefficient; T is the gas temperature.

[0103] Optionally, the detection result includes whether erosion has not occurred or whether erosion has occurred; based on the safety management type and the detection result, safety management measures for the tested pipe string are determined, including:

[0104] When the safety management type is pipeline erosion and the detection result is that no erosion has occurred, the sensor data matching the erosion monitoring strategy corresponding to the pipeline erosion is continuously monitored in real time;

[0105] When the safety management type is pipeline erosion and the test result is erosion, the erosion condition of the pipe string to be tested is obtained;

[0106] When the erosion condition is non-destructive erosion, the injection and production volume of the pipe string to be tested is reduced so that the pipe string to be tested is injected and produced based on the reduced injection and production volume, and the sensor data matching the erosion monitoring strategy corresponding to the pipeline erosion is continuously monitored in real time;

[0107] When the erosion condition is destructive erosion, a second alarm message is sent to the terminal device, and the gas leakage condition of the pipe string to be tested is obtained, and a second repair strategy for the pipe string to be tested is determined based on the gas leakage condition.

[0108] In this embodiment, when the safety management type is pipeline erosion, and the detection result is that no erosion has occurred, it means that the situation of pipeline erosion in the tested pipe string will not affect the use of the tested pipe string. At this time, it is only necessary to continue to monitor the tested pipe string in real time, so as to understand the situation of pipeline erosion in the tested pipe string at any time. When the safety management type is pipeline erosion, and the detection result is that erosion has occurred, it means that the situation of pipeline erosion in the tested pipe string will affect the use of the tested pipe string. At this time, it is necessary to conduct a specific analysis of the erosion situation of the tested pipe string. If the erosion situation is non-destructive erosion, it means that the situation of pipeline erosion in the tested pipe string will have a slight impact on the use of the tested pipe string. At this time, it is only necessary to reduce the injection and production volume of the tested pipe string. As long as the tested pipe string is injected and produced based on the reduced injection and production volume, it will not affect the use of the tested pipe string. At the same time, continue to monitor the tested pipe string in real time, so as to understand the situation of pipeline erosion in the tested pipe string at any time. If the erosion is destructive erosion, it means that the pipe string to be tested cannot be used normally. Then, a second alarm message is sent to the terminal device, so that the staff can timely understand the destructive erosion of the pipe string to be tested and respond to the destructive erosion in time. For the destructive erosion, the second repair strategy is determined according to the leakage of the pipe string to be tested, and the pipe string to be tested is repaired based on the second repair strategy, thereby realizing the safe management of the pipe string to be tested and improving the safety of the management process of the pipe string to be tested.

[0109] In this embodiment, the leakage of the pipe to be tested is determined based on the difference between the real-time flow rate and the standard flow rate in the pipe to be tested, and / or the change of the gas content in the pipe to be tested. The leakage situation includes the leakage volume per unit time. If the leakage volume per unit time is less than or equal to the preset leakage volume, it means that the leakage caused by erosion in the pipe to be tested is not serious and can be used normally after repair. Then the second repair strategy can be to use at least one repair technology of thermal spraying, sealant, and anti-erosion coating to repair the pipe to be tested, and continuously monitor the pipe to be tested in real time, so as to understand the erosion of the pipe in the pipe to be tested at any time. If the leakage volume per unit time is greater than the preset leakage volume, it indicates that the leakage of the pipe string to be tested is serious, and the leakage caused by erosion in the pipe string to be tested cannot be repaired to a state where it can be used normally. In this case, the currently eroded pipe string to be tested is discarded, and the parameters of a new pipe string are determined based on factors such as material, pipe diameter, steel grade, wall thickness, inner diameter, and line weight. The pipe string to be tested is replaced with the new pipe string, and the new pipe string is continuously monitored in real time to facilitate the understanding of the erosion of the pipeline in the new pipe string at any time.

[0110] In this embodiment, the specific steps of obtaining the erosion condition of the pipe string to be tested may include:

[0111] When the absolute value of the difference between the equivalent diameter and the true diameter is less than or equal to a preset threshold, the erosion condition of the pipe string to be tested is determined to be non-destructive erosion;

[0112] When the absolute value of the difference between the equivalent diameter and the true diameter is greater than a preset threshold, it is determined that the erosion condition of the pipe string to be tested is destructive erosion.

[0113] Optionally, the method further comprises:

[0114] Generate string safety inspection and hazard prevention reports based on inspection results and safety management measures;

[0115] Store string safety inspection and hazard prevention reports in a preset database.

[0116] In this embodiment, the detection results obtained by real-time detection and the corresponding safety management measures are automatically filled in according to the preset report requirements, and the pipe string safety detection and hazard prevention report is obtained and stored in the preset database. In this way, the staff can check the historical safety management of the pipe string to be tested at any time, and perform maintenance on the pipe string to be tested in a timely manner, thereby further improving the safety of the management of the pipe string to be tested.

[0119] Figure 3 This is a flow chart of a safety management method for a pipe string provided in an exemplary embodiment of the present application, as shown in FIG. Figure 3 As shown, the method of the present application is aimed at the safety detection and prediction of gas (energy) storage pipe strings. Figure 3In the present invention, when it is necessary to monitor the pipeline corrosion of the pipe column, first determine whether the pipe material type of the pipe column monitored on site is ferromagnetic material. If so, use ultrasonic detection technology to detect whether there is pipeline corrosion in the pipe column. If not, use eddy current detection technology to detect whether there is pipeline corrosion in the pipe column. When there is pipeline corrosion, use pressure sensor to detect the operating pressure of the pipe column at the corroded part of the pipe column. At the same time, according to the relevant information of the pipe material, that is, the pipe column information, using ASMEB31G standard, DNVRPF101 specification or PCORRC specification, based on the pipe column information and the corrosion information of the corroded part of the pipe column, the residual strength of the pipe column is calculated from multiple angles: the residual strength of the first pipe column, the residual strength of the second pipe column and the residual strength of the third pipe column, and multiple linear regression is performed on the three residual strengths to obtain the target residual strength of the pipe column. The pressure ratio is calculated based on the operating pressure of the pipe column and the target residual strength, and the detection result of the pipe column is determined to be a conservative safety state (stable safety state), a temporary safety state (unstable safety state) or an unsafe state based on the pressure ratio. When the test result is a conservative safety state, the pipe string is continuously monitored in real time; when the test result is a temporary safety state, the injection and production volume of the pipe string is reduced, and then the pipe string is continuously monitored in real time; when the test result is an unsafe state, the first alarm information is sent to the terminal device, and it is determined whether a rescue well is needed. When a rescue well is needed, the rescue well is drilled and then closed. When a rescue well is not needed, the rescue well is closed. When performing a rescue well, the repair value is determined based on the residual value of the pipe string. When the repair value is greater than or equal to the preset value, it means that the pipe string can be repaired, and at least one repair technology selected from anti-corrosion coating, corrosion inhibitor, plating technology, and cathodic protection is used to repair the pipe string, and the repaired pipe string is operated normally, and the pipe string is continuously monitored in real time; when the repair value is less than the preset value, it means that the pipe string cannot be restored, and the pipe string is replaced with a new pipe string, and the new pipe string is operated, and the new pipe string is continuously monitored in real time.

[0120] Figure 3In the process of pipeline erosion detection, since erosion is easy to occur at the wellhead and bottom of the pipe string, sensor groups are installed at the wellhead and bottom of the pipe string. The flow pressure, erosion velocity and erosion flow rate are detected by the sensor groups installed at the wellhead and bottom of the well according to the real-time monitoring on site. Combined with CFD simulation or erosion calculation mathematical model, a simulation model of the pipe string is constructed. Using the simulation model and the measured flow pressure, erosion velocity and erosion flow rate, it is judged whether erosion has occurred in the pipe string, and the pipe string is continuously monitored in real time when no erosion occurs. When erosion occurs, the erosion of the pipe string at the wellhead and bottom of the well is detected. The erosion situation is judged by the leakage situation of the pipe string. The leakage situation includes the leakage volume per unit time. If the leakage volume per unit time is less than or equal to the preset leakage volume, it means that the leakage caused by erosion in the pipe string is not serious, that is, the erosion is not obvious. Then, after reducing the injection and production gas volume, it will not affect the use of the pipe string. At this time, the pipe string continues to be monitored in real time; if the leakage volume per unit time is greater than the preset leakage volume, it means that the leakage of the pipe string is serious, that is, the erosion is obvious, and the second alarm information is sent to the terminal device. A second repair strategy for the pipe string is determined based on the leakage situation of the pipe string. If the leakage amount per unit time is less than or equal to the preset leakage amount, the second repair strategy may be to repair the pipe string using at least one repair technology selected from thermal spraying, sealant, and anti-erosion coating, and to operate the repaired pipe string normally, and to continuously monitor the pipe string in real time. If the leakage amount per unit time is greater than the preset leakage amount, the second repair strategy may be to abandon the currently eroded pipe string, and to determine the parameters of a new pipe string based on factors such as material, pipe diameter, steel grade, wall thickness, inner diameter, and line weight, and to replace the pipe string with the new pipe string, and to operate the new pipe string, and to continuously monitor the new pipe string in real time.

[0121] The safety management method of the pipe string provided in the above-mentioned embodiment of the present application uses data collected by sensors to monitor the corrosion and erosion in the pipe string in real time. At the same time, through CFD simulation and erosion calculation mathematical model, the erosion calculation chart is completed, and the theoretical calculation model is combined with the actual field detection data to determine whether erosion occurs in the pipe string, which helps to discover the corrosion and erosion problems in the pipe string as early as possible, and determine the corresponding safety management measures for rectification, thereby avoiding the occurrence of pipe string failure, while eliminating a large number of regular inspections and manual data collection, reducing manpower and operating costs. This application improves the monitoring efficiency and maintainability of the pipe string through automation and remote monitoring, and has higher flexibility and adaptability. It can also be adjusted according to the operating conditions and environmental changes of different pipe strings, thereby providing more accurate prediction results.

[0122] The method of the present application can be used to monitor the safety status of the pipe string system of gas storage and energy storage in real time. The sensor group collects and analyzes data related to the flow, pressure, flow rate, etc. of the pipe string, and combines the theoretical calculation model to continuously evaluate the performance and safety of the pipe string. It can monitor abnormal conditions in the pipe string system in real time, such as corrosion, erosion, and flow and pressure fluctuations. Once an abnormality is detected, an alarm is issued in real time, and necessary measures are taken to prevent accidents. It helps to discover potential problems in advance, take preventive maintenance measures, and reduce the risk of failure. By providing real-time pipe string status information, the process method of the present invention can also be used to optimize pipe string operations. Decisions on maintenance or replacement are made based on data to improve efficiency, reduce energy costs, and extend the life of the pipe string. For the energy industry, ensuring the safety of the pipe string system is crucial. In the present application, the following effects are achieved: (1) Based on scientific laws, high-precision sensors and real-time data acquisition technology are reasonably set up to monitor the status of the pipe string in real time, and an alarm can be generated immediately to notify the ground data analysis and processing center whether there is an abnormality in the pipe string, thereby eliminating monitoring delays. (2) Ultrasonic and magnetic technologies can detect and predict hidden problems inside the pipe, which helps to detect and correct them early and avoid pipe failure events. (3) Through automation and remote monitoring, the need for regular inspections and manual data collection is reduced, thereby reducing human resources and operating costs. (4) It provides an innovative and efficient method for pipe safety monitoring, aiming to reduce the risk of failure, improve the reliability and safety of the pipe system, and reduce costs and human resources requirements. It has broad application potential in the energy industry and related fields.
