DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to Figure 1 , Figure 1 FIG. 1 is a flow chart of an earthquake monitoring method based on gas storage reservoir structural parameters according to an embodiment of the present invention. Figure 1 As shown, the method may include steps S101 to S109: Step S101: Collecting seismic geological data, engineering geological and structural design information of the gas storage construction area, wherein the seismic geological data include: historical regional earthquake records and seismic motion parameters of the gas storage construction area, and the engineering geological and structural design information include: regional rock and soil layer distribution characteristics, groundwater conditions, geostress field, rock and soil physical and mechanical parameters, gas storage body design parameters, and gas storage structure parameters.

[0025] In this embodiment, since earthquakes are low-probability events, a project may not encounter an earthquake during its 50-year operation period. Therefore, it is necessary to collect historical earthquake geological data and combine them with engineering geology and structural design information to simulate the possible impacts on the gas storage facility under different earthquake conditions.

[0026] For example, seismic geology data, engineering geology, and structural design information can be obtained through open source database downloads, drone measurements, and purchases.

[0027] Step S102: Based on the historical regional earthquake records and seismic parameters of the gas storage construction area, multiple groups of random seismic time history records with different exceedance probabilities are generated.

[0028] In this embodiment, multiple groups of random seismic time history records with different exceedance probabilities can be obtained by using, but not limited to, the Monte Carlo simulation method. The exceedance probability is the probability that the gas storage facility may encounter an earthquake intensity value greater than or equal to a given seismic intensity value or seismic parameter value within a certain period of time. The seismic time history describes the process of changes in seismic acceleration, velocity or displacement over time, and includes three key elements, namely, the intensity, spectrum and duration of the seismic motion. The intensity is usually characterized by the maximum amplitude (such as the peak acceleration); the spectral characteristics reflect the intensity distribution of different frequency components; and the duration affects the final degree of damage to the structure, especially the structural response in the nonlinear stage.

[0029] By using multiple sets of random seismic time history records with different random exceedance probabilities, the impact of earthquakes of different magnitudes when they actually occur can be simulated.

[0030] Step S103: establishing a three-dimensional numerical simulation model based on the seismic geological data and the engineering geological and structural design information.

[0031] In this embodiment, the three-dimensional numerical simulation model of the gas storage reservoir can be established by, but not limited to, using a finite element structural model establishment method.

[0032] In the present application, a simulation model can be established for an existing gas storage facility, a risk assessment of the gas storage facility can be conducted, and suggestions can be given for its corresponding earthquake risk management. At the same time, a simulation model can also be established for a gas storage facility that has not yet been built based on its design data, and a risk assessment of the gas storage facility can be conducted to estimate the earthquake risk that it may subsequently suffer.

[0033] Step S104: using the generated multiple groups of random seismic time history records under different exceedance probabilities as input conditions, performing dynamic response calculation of the three-dimensional numerical simulation model to obtain damage degree information, wherein the damage degree information includes: the damage range of the sealing layer and the damage range of the lining.

[0034] In this embodiment, multiple groups of random seismic time history records with different exceedance probabilities are generated as input conditions to simulate earthquake conditions of different degrees. The process of calculating the dynamic response of the three-dimensional numerical simulation model can be carried out by but not limited to the method of using dynamic analysis model calculation to finally obtain the specific impact of different earthquake conditions on the gas storage, that is, the damage degree information.

[0035] In this application, since the gas storage has higher requirements on structural stability and airtightness, the damage degree information of the gas storage is determined by the damage range of the sealing layer and the lining.

[0036] Step S105: using a risk quantitative assessment model, according to the exceedance probability in the input conditions and the damage degree information under the earthquake conditions, to obtain the earthquake risk cost under the input conditions.

[0037] In this embodiment, a monetary risk quantitative evaluation model is used to evaluate the impact of earthquakes on gas storage operations based on the probability of earthquake occurrence and the degree of damage under the earthquake conditions. The earthquake risk cost includes the repair cost, that is, the earthquake risk cost under a certain earthquake intensity, and the production loss, that is, the time cost impact of repairing the losses caused by the earthquake.

[0038] Step S106: Based on the earthquake risk cost, corresponding risk control measures are created to obtain a library of disposal methods under earthquake motion conditions of different intensities.

[0039] In this embodiment, based on the earthquake risk cost, the repair measures to be taken for the gas storage when it is affected by earthquakes of different degrees are integrated and classified. The collection of different response and treatment measures is the disposal method library.

[0040] Different methods should be adopted according to the different degrees of damage suffered by the gas storage facility. For example, if the damage is minor, only filling and repair can be considered. If there is extensive damage, structural reinforcement or overall replacement will need to be considered.

[0041] Step S107: construct an earthquake risk assessment model based on multiple groups of random earthquake motion time history records under different exceedance probabilities and corresponding earthquake risk costs, and determine risk control measures plans that match different earthquake risk costs in the disposal method library.

[0042] In this embodiment, multiple sets of earthquake risk cost calculation results can be integrated through but not limited to the use of machine learning methods to construct an earthquake risk assessment model for predicting the disasters that may be caused by subsequent earthquakes, and matching it with a disposal method library to obtain risk control measures that match different earthquake risk costs.

[0043] Step S108: During the operation of the current gas storage, the seismic motion in the area where the current gas storage is located and the stress level of the gas storage structure are monitored.

[0044] In this embodiment, during the actual operation of the gas storage facility, real-time seismic monitoring should be carried out in the surrounding areas to provide timely warning and response to possible earthquake disasters. At the same time, the structural stress level of the gas storage facility itself should be monitored. Since the structural stability of the gas storage facility can be reflected by the structural stress level, monitoring the structural stress level of the gas storage facility itself can ensure that problems are discovered and handled in a timely manner, which is beneficial to the maintenance and use of the gas storage facility.

[0045] Step S109: Assess the earthquake risk cost of the current gas storage reservoir through an earthquake risk assessment model, and output corresponding risk control measures.

[0046] In this embodiment, after the earthquake risk assessment model is established, the earthquake risk cost of the gas storage facility can be judged at any time according to the seismic conditions in the current area. Therefore, when an actual earthquake occurs, the earthquake risk can be timely assessed through the earthquake assessment model associated with the disposal method library, and corresponding response plans can be made.

[0047] In combination with the above embodiments, in one implementation, the present invention further provides a seismic monitoring method based on gas storage reservoir structural parameters. In the method, the above step S104 may specifically include steps S201 to S202: Step S201: Based on the generated multiple groups of random seismic time history records under different exceedance probabilities as input conditions, dynamic response calculation of the three-dimensional numerical simulation model is performed, and the stress of the sealing layer and the lining under each group of the input conditions is recorded.

[0048] In this embodiment, the damage degree information includes at least: the damage range of the sealing layer and the damage range of the lining. Among them, the generated multiple groups of random seismic time history records under different exceedance probabilities are used as input conditions to simulate earthquake conditions of different degrees. The process of dynamic response calculation of the three-dimensional numerical simulation model can be achieved by, but not limited to, using the method of dynamic analysis model calculation, and finally obtain the specific impact of different earthquake conditions on the gas storage. The specific manifestation of the damage to the sealing layer and the lining is the stress received by the sealing layer and the lining.

[0049] Step S202: The allowable stress of the sealing layer material is σ Rs , the allowable stress of the lining material is σ Rc In each group of calculation results, the sealing layer stress is greater than the allowable stress σ Rs The total volume of the region V s , is determined as the damage range of the sealing layer; the lining stress is greater than σ Rc The total volume of the region V c , determined as the damage range of the lining.

[0050] In this embodiment, the damage of the sealing layer and lining can be judged by calculating the stress borne by the sealing layer and lining. The allowable stress threshold of the sealing layer and lining of the gas storage reservoir can be obtained through the gas storage reservoir design documents and actual construction information. When the sealing layer or lining is subjected to stress exceeding the threshold, it can be regarded as damaged. By calculating the total volume of the area subjected to stress exceeding the allowable stress, the damage range of the sealing layer or lining can be obtained.

[0051] In combination with the above embodiments, in one implementation, the present invention further provides a seismic monitoring method based on gas storage reservoir structural parameters. In the method, the above step S105 may specifically include steps S301 to S303: Step S301: Determine the repair cost C according to the damage range of the sealing layer and the damage range of the lining. repair , the repair cost C repair The amount of work used to reflect the repair work.

[0052] In this embodiment, the damage range of the sealing layer and the damage range of the lining are used to determine the repair cost C repair According to the extent of the damage, the amount of work required for the repair project will also vary, and the economic cost of the repair project will also vary accordingly. The repair of the gas storage facility includes the repair of the sealing layer and the repair of the lining.

[0053] Step S302: Determine the production reduction loss C according to the number of days of shutdown and the daily benefit of the energy storage power station. loss The number of days of suspension of production is related to the workload of the repair project.

[0054] In this embodiment, the earthquake risk cost also includes the production loss C loss After suffering an earthquake disaster, the energy storage power station supplied by the gas storage reservoir cannot continue to work during the repair process. Therefore, the earthquake risk cost includes not only the repair cost of the gas storage reservoir, but also the economic loss caused by the suspension of the energy storage power station. The number of days of suspension depends on the degree of damage to the gas storage reservoir. The greater the degree of damage, the greater the amount of repair work and the more days of suspension. The smaller the degree of damage, the smaller the amount of repair work and the fewer days of suspension. The loss of production reduction C loss It is also related to the daily benefits of the energy storage power station. The product of the daily economic benefits of the energy storage power station and the number of days of shutdown is the production loss C. loss .

[0055] Step S303: P f ×(C repair +C loss ) is determined as the earthquake risk cost, where P f is the probability of occurrence of earthquake intensity at the site.

[0056] In this example, the earthquake risk cost is not only affected by the repair cost C repair and production loss C loss The two aspects of influence also depend on the probability of occurrence of earthquake intensity P at the gas storage site. f The probability of occurrence includes the probability of earthquake occurrence and the probability that the earthquake intensity will cause damage to the gas storage. Taking the three factors into consideration, the earthquake risk cost P of the earthquake risk assessment model is constructed. f ×(C repair +C loss ).

[0057] In combination with the above embodiments, in one implementation, the present invention further provides a seismic monitoring method based on gas storage reservoir structural parameters. In the method, the above step S107 may specifically include step S401: Step S401: using the multiple groups of random seismic time history records under different exceedance probabilities and the corresponding earthquake risk costs as training samples, training the machine learning model to obtain the earthquake risk assessment model.

[0058] In this embodiment, first, for each sample seismic time history record, the sample seismic time history record is marked according to whether the sample seismic time history record indicates that the earthquake will cause damage to the three-dimensional numerical simulation model. The marking process can be completed manually, that is, manually judging whether the sample seismic time history record poses a risk to the three-dimensional numerical simulation model, and then marking the sample seismic time history record, so that the sample seismic time history record carries the mark.

[0059] Each sample seismic time history record is marked according to the above process, thereby obtaining a plurality of sample seismic time history records carrying marks.

[0060] Then, features are extracted from each labeled sample seismic time history record, and the extracted features are input into a classifier (e.g., softmax, Bayesian, SVM, xgboost) for training until the first preset model after training has the function of predicting the probability of a three-dimensional numerical simulation model suffering from earthquake risk represented by a single seismic time history record. The first preset model after training is the earthquake risk assessment model.

[0061] Finally, after obtaining the earthquake risk assessment model, for a single seismic motion time history record, for example, the seismic motion time history record of an actual earthquake, the single seismic motion time history record can be input into the earthquake risk assessment model, and the earthquake risk assessment model can be used to predict the probability that the gas storage facility may be subject to earthquake risk represented by the seismic motion time history record.

[0062] In combination with the above embodiments, in one implementation, the present invention further provides a seismic monitoring method based on gas storage reservoir structural parameters. In the method, the above step S102 may specifically include steps S501 to S502: Step S501: Determine the upper and lower limits of the ground motion intensity PGA based on the historical regional earthquake records in the gas storage construction area.

[0063] In this example, due to the regional nature of earthquake risk assessment, for the northwestern region where earthquakes are more frequent, establishing upper and lower limits of earthquake intensity can more specifically simulate possible earthquake situations, and the random seismic motion time history records used as input are more realistic.

[0064] Step S502: For the target PGA, based on the Monte Carlo simulation method, with PGA as the target value, generate the multiple groups of random seismic time history records under different exceedance probabilities.

[0065] In this example, multiple groups of random seismic time history records with different exceedance probabilities can be obtained by, but not limited to, using the Monte Carlo simulation method. The Monte Carlo simulation method establishes a probability model or a random process so that its parameters or numerical characteristics are equal to the solution of the problem: these parameters or numerical characteristics are then calculated through observation or sampling tests of the model or process, and finally the approximate value of the solution is given. The error of this method is independent of the dimension of the problem. It can directly solve problems with statistical properties, and there is no need to discretize continuous problems. In the application of random seismic time history record simulation, the randomness of earthquake occurrence can be simulated more accurately, and a large amount of data input can be provided for the establishment of a reliable earthquake risk assessment model.

[0066] In combination with the above embodiments, in one implementation, the present invention further provides a seismic monitoring method based on gas storage reservoir structural parameters. In the method, the above step S106 may specifically include steps S601 to S602: Step S601: Based on the earthquake risk cost, risk control measures for corresponding engineering quantities are created, wherein the risk control measures include: strengthening structures, sealing and repairing, and increasing emergency reserves.

[0067] In this example, based on the earthquake risk cost, targeted risk control measures are proposed, such as strengthening structures, sealing and repairing, and increasing emergency reserves (the engineering volume of the emergency measures plan is totaled according to the earthquake risk cost). According to the specific quantified risk cost obtained by the risk assessment model, corresponding emergency reserves can be made to quickly respond to earthquake damage when an earthquake disaster occurs.

[0068] Step S602: Risk control measures are created for different earthquake risk costs to form a disposal method library under earthquake motion conditions of different intensities.

[0069] In this example, due to the randomness of earthquake occurrence, different degrees of response measures should be taken for different degrees of earthquake damage. Therefore, the risk assessment model can be used to estimate the loss of gas storage caused by the earthquake, evaluate the amount of post-disaster repair work, and form a disposal plan based on the amount of work. A library of disposal methods under different intensities of seismic motion conditions can be formed. After an extreme disaster occurs, the speed of risk response can be improved to provide support for the risk management plan.
