[0033] like Figure 1As shown, the pipeline seismic data quality optimization and risk assessment level prediction system 001 includes at least one processor 011 and a memory 012 that is communicatively connected to the at least one processor; wherein the memory 012 stores instructions that can be executed by the at least one processor 011, and the instructions are executed by the at least one processor 011 so that the at least one processor 011 can execute the pipeline seismic data quality optimization and risk assessment level prediction method provided in an embodiment of the present application.

[0034] Figure 2 A flow chart of a pipeline seismic data quality optimization and risk assessment level prediction method provided in an embodiment of the present application. Figure 2 As shown, in some embodiments, the pipeline seismic data quality optimization and risk assessment level prediction method includes the following steps:

[0035] S1, collecting risk data to obtain a first risk data set, a second risk data set and a third risk data set.

[0036] The risk data is a plurality of groups of data related to the oil and gas pipeline earthquake risk level. Each group of the data includes a type of indicator of the oil and gas pipeline earthquake risk factor and the corresponding risk situation. The risk situation can be indicated by risk classification. In one implementation, the number of groups of risk data is 129.

[0037] There are many types of risk data collected. For example, indicators related to the pipeline risk factors include pipeline steel grade, minimum yield strength of pipes, burial depth, pipeline defect type, number of pipeline defects, geological conditions, number of elbows, soil liquefaction, faults, river bank landslides and mountain landslides. For another example, indicators related to the earthquake hazard include earthquake fault zones, earthquake history within a preset number of years, earthquake peak acceleration and distance from the epicenter. For another example, the degree of pipeline damage or pipeline damage status. The degree of pipeline damage is divided into four categories. Exemplarily, the degree of pipeline damage includes the operable limit state, the pressure integrity limit state, the complete limit state, and the global collapse limit state.

[0038] The pipeline damage state can be divided into tensile stress or strain state, compressive stress or strain state, and buckling stress or strain state;

[0039] There are many ways to collect risk data, such as on-site seismic surveys and finite element simulations.

[0040] When data is collected by on-site seismic survey, it is advisable to use pipeline leakage or connection failure as the rating.

[0041] When finite element simulation is used, Abaqus or OpenSees may be used. In some embodiments, when executing step S1, the pipeline seismic data quality optimization and risk assessment level prediction method further includes:

[0042] S11, according to the laying conditions of the oil and gas pipeline, through multi-parameter calculation, the stress and strain results of the oil and gas pipeline under different laying conditions are obtained.

[0043] In some embodiments, the laying conditions include three laying areas: soil liquefaction area, landslide area, and fault area. In different laying areas, multiple parameters including pipeline angle, pipeline strength grade, and pipeline thickness have different values. When performing finite element analysis, calculations are performed based on different parameter values.

[0044] S12, obtain the risk level based on the stress-strain results.

[0045] The stress-strain results are the maximum stress-strain of the pipeline under earthquake conditions under different conditions, which are used to indicate different pipeline damage states. Risk classification is performed based on the pipeline damage state.

[0046] The first risk data set is used as the training set.

[0047] The second risk dataset is used as a test set.

[0048] The third risk data set is used as the set to be evaluated.

[0049] S2: training multiple risk models based on the first risk data set.

[0050] In some embodiments, the multiple risk models include artificial neural network model (ANN), random forest model, decision tree model, support vector machine model (SVM), gradient boost model, naive Bayes model, adaptive algorithm model (Adaptive Boosting, AdaBoost) and prior data fitting network model (Tab Prior-Data Fitted Network, TabPFN).

[0051] AdaBoost is a binary classifier.

[0052] The random forest algorithm generates the number of sub-datasets by sampling the original data set with replacement through the number of decision trees (n_estimators), that is, the number of decision trees. min_samples_leaf sets the number of samples on the leaves of each decision tree. If the number is less than the set value, it will be pruned. It is set to 2. The min_samples_split parameter sets the minimum number of samples required for a decision tree to form a new branch. If the number is less than the set value, it will no longer branch. It is set to 2.

[0053] In some embodiments, the artificial neural network model uses a sequential model to construct a three-layer neural network. Each layer of the neural network includes an input layer, a first hidden layer, a second hidden layer and an output layer. The first hidden layer is provided with a first activation function. The second hidden layer is provided with a first activation function. The output layer is provided with a second activation function. In one implementation, the input layer includes N nodes, where N is a collection parameter. The first hidden layer includes 64 neurons. The second hidden layer includes 32 neurons. The output layer includes 1 neuron. In one example, the first activation function is a relu function. The second activation function is a sigmoid function.

[0054] In some embodiments, when training multiple risk models based on the first risk data set, the risk model is a decision tree model, and the pipeline seismic data quality optimization and risk assessment level prediction method further includes:

[0055] S21, based on information entropy and Gini index, the parameters of the risk model are optimized.

[0056] Gini and Entropy are used to screen features respectively.

[0057] The calculation formula of information entropy includes:

[0058]

[0059] Where D represents the current sample set; k represents the total number of sample categories; p k It is expressed as the proportion of the k-th sample category in D.

[0060] It can be understood that the smaller the value of Ent(D), the higher the purity of D.

[0061] In one implementation, the value of k corresponding to binary classification is "2".

[0062] In some embodiments, the Gini index is used to classify features. The calculation formula of the Gini index includes:

[0063]

[0064] The criterion parameter is used to set the impurity judgment method, using the Gini criterion.

[0065] In some embodiments, when training multiple risk models based on the first risk data set, the risk model is a gradient boosting model, and the pipeline seismic data quality optimization and risk assessment level prediction method further includes:

[0066] S201, through grid search, find the optimal parameters and optimize the parameters of the risk model.

[0067] In some embodiments, based on the gridsearch traversal, the optimal parameters are determined to be a learning rate of 0.05, a maximum depth of 3, and n_estimators of 200.

[0068] The two parameters of Accuracy and precision are used to evaluate the model effect. Accuracy is defined as (TP+TN) / (TP+TN+FP+FN), and precision is defined as TP / (TP+FP), where TP is predicted to be positive and the actual result is positive; FP is predicted to be positive and the actual result is negative; TN is predicted to be negative and the actual result is negative; and FN is predicted to be negative and the actual result is positive.

[0069] S3, inputting the second risk data set into each risk model to obtain the risk result output by each risk model.

[0070] S4, based on the risk results of each risk model, an error data set is obtained.

[0071] S5, eliminating the erroneous data set from the third risk data set to obtain a fourth risk data set.

[0072] In this way, the goal of optimizing data quality is achieved.

[0073] S6. Based on the fourth risk data set, train each risk model to obtain a target risk model.

[0074] The embodiments of the present application can improve the quality of pipeline seismic data collection through multi-model cross-validation, and obtain a model with higher prediction accuracy, thereby achieving accurate and dynamic prediction of pipeline seismic risk levels.

[0075] This application establishes a connection between risk factors and risk levels. After the oil and gas pipeline to be tested inputs data into the target risk model, the risk results obtained are more accurate.

[0076] A comparison is given below between the method provided in the embodiment of the present application (after optimization) and the method not provided (before optimization) to illustrate the effect of the present application.

[0078]

[0079] As shown in Table 1, the data that were predicted incorrectly by all eight models were extracted to observe the problems in the model predictions, and the data that were predicted incorrectly were eliminated.

[0080] like Figure 3 and Figure 4 As shown in the figure, by comparison, the prediction accuracy of the eight models is further improved. It can be seen that Gradientboost has achieved the maximum prediction accuracy of 100%, indicating that the trained model can effectively predict the pipeline seismic risk level.
