[0032] S110, obtain the attribute information of the active fault where the pipeline to be detected is located.

[0033] In this embodiment, the attribute information of the active fault where the pipeline to be detected is located may include: peak ground acceleration and the thickness from the bottom of the pipe to the bedrock soil layer.

[0034] S120, if the attribute information of the active fault where the pipeline to be detected is located does not meet the preset conditions, then obtain the stress-strain function corresponding to the first rule, the stress-strain threshold corresponding to the first rule, the measured pipeline centerline parameters of the pipeline to be detected, the seismic parameters corresponding to the target pipeline seismic type, the steel pipe specification parameters, the welding process parameters, and the anti-corrosion layer parameters.

[0038] In this embodiment, the stress-strain function corresponding to the first rule may be determined based on the current standard specifications, and the current standard specifications may include: the seismic technical code for oil and gas pipeline line engineering.

[0039] In this embodiment, both the stress-strain function corresponding to the first rule and the stress-strain threshold corresponding to the first rule may be obtained by querying the design document corresponding to the pipeline to be detected, and the embodiments of the present invention do not limit this.

[0040] In this embodiment, it is necessary to pre-collect the engineering data of the pipeline to be detected. The content and sources of the collected data are as follows: The pipeline seismic special report or design report, which is used to determine the pipeline laying scheme, engineering measures and their technical indicators, and can be obtained from the operation unit or the design unit; The construction drawing specifications and drawings, which are used to determine the pipeline laying scheme, engineering measures and their technical indicators, and can be obtained from the operation unit, the design unit or the construction unit; The seismic safety evaluation report, which is used to determine the nature, occurrence and parameters of active faults, and can be obtained from the operation unit or the design unit; The exploration data, which is used to determine the nature, occurrence and parameters of active faults, and can be obtained from the operation unit or the design unit; The technical specifications and data sheets of the line steel pipe, which are used to determine the mechanical property index requirements of the steel pipe crossing the active fault, and can be obtained from the operation unit or the design unit; The quality certificate of the steel pipe, which is used to determine the mechanical properties of the steel pipe crossing the active fault, and can be obtained from the steel pipe manufacturer or the construction unit; The special report on welding and non-destructive testing, which is used to determine the mechanical properties of girth welds and the allowable defect index requirements, and can be obtained from the operation unit or the design unit; The welding procedure qualification report, which is used to determine the mechanical properties of girth welds, and can be obtained from the construction unit or the welding procedure qualification unit; The information of the pipeline external anti-corrosion layer, which is used to determine the friction coefficient and deformation index of the pipe-soil interaction, and can be obtained from the operation unit or the design unit.

[0041] Determine the pipeline laying scheme, engineering measures, technical indicators, the nature, occurrence of active faults, the mechanical property indicators of the steel pipe crossing the active fault, the mechanical properties of girth welds, the allowable defect indicators, the friction coefficient of pipe-soil interaction and the deformation index according to the pre-collected engineering data of the pipeline to be detected.

[0042] Check whether the collected engineering data is complete. If it is complete, the pipeline seismic performance detection can be carried out. If it is not complete, the engineering materials should be supplemented and collected.

[0043] Specifically, when the engineering data meets the following conditions, it is determined that the engineering data is complete: It can determine the pipeline laying scheme, engineering measures and technical indicator requirements for the pipeline to pass through the active fault; It can determine the nature, occurrence and parameters of the active fault, including the location, occurrence, thickness of the overlying soil layer, dislocation nature, dislocation amount, width of the fracture zone and width of the influence zone, etc.; It can determine the site engineering geological conditions; It can determine the mechanical property index requirements of the steel pipe crossing the active fault; It can determine the mechanical properties of the steel pipe crossing the active fault; It can determine the mechanical properties of girth welds and the allowable defect index requirements; It can determine the mechanical properties of girth welds. When information such as the nature, occurrence and parameters of the active fault is missing, the supplementary exploration work of the active fault should be carried out according to the provisions of the Seismic Design Code for Oil and Gas Transmission Pipeline Projects, the Code for Geotechnical Investigation and the Standard for Geotechnical Investigation of Oil and Gas Fields and Pipelines.

[0044] Optionally, the attribute information of the active fault where the pipeline to be detected is located includes: the peak ground acceleration and the thickness of the soil layer from the pipe bottom to the bedrock;

[0045] The preset conditions include:

[0046] The peak ground acceleration of the earthquake motion is less than or equal to a first value, and the thickness from the bottom of the pipe to the bedrock soil layer is greater than or equal to a second value.

[0047] In this embodiment, the first value can be 0.3g, and the second value can be 60 meters. The embodiments of the present invention do not limit this.

[0048] Or, the peak ground acceleration of the earthquake motion is greater than the first value, and the thickness from the bottom of the pipe to the bedrock soil layer is greater than or equal to a third value.

[0049] In this embodiment, the third value is greater than the second value; the third value can be 90 meters.

[0050] It should be noted that according to the seismic design code for oil and gas transmission pipeline line projects, combined with the collected engineering data, it is judged whether the active fault at this place needs to be fortified. If it is judged that no fortification is required, the process can be directly ended without performing pipeline seismic performance detection; otherwise, pipeline seismic performance detection is required.

[0051] In this embodiment, if the preset conditions are met, pipeline seismic performance detection is not required.

[0052] S130. Substitute the measured pipeline center line parameters of the pipeline to be detected, the seismic parameters corresponding to the target pipeline seismic type, the steel pipe specification parameters, the welding process parameters, and the anticorrosion layer parameters into the stress-strain function corresponding to the first rule to obtain the measured stress-strain value corresponding to the first rule.

[0053] S140. Determine the seismic performance detection result according to the measured stress-strain value corresponding to the first rule and the stress-strain threshold corresponding to the first rule.

[0054] In this embodiment, the seismic performance detection result can be the seismic performance grade. For example, if the seismic performance detection result is the first grade of the seismic performance grade, it is determined that the pipeline seismic measures do not need to be rectified; if the seismic performance detection result is the second grade of the seismic performance grade, it is determined that the pipeline seismic measures will be rectified at a selected time; if the seismic performance detection result is the third grade of the seismic performance grade, it is determined that the pipeline seismic measures will be rectified within a time limit.

[0055] In this embodiment, the method for determining the seismic performance detection result based on the measured stress-strain value corresponding to the first rule and the stress-strain threshold corresponding to the first rule may be as follows: If the measured stress-strain value corresponding to the first rule is greater than or equal to the stress-strain threshold corresponding to the first rule, the seismic performance level is determined to be the first level; if the measured stress-strain value corresponding to the first rule is less than the stress-strain threshold corresponding to the first rule, the seismic performance level is determined based on the measured pipeline centerline parameters of the pipeline to be detected, the seismic parameters corresponding to the seismic type of the target pipeline, the steel pipe specification parameters, the welding process parameters, and the stress-strain threshold corresponding to the second rule.

[0056] Optionally, determining the seismic performance detection result based on the measured stress-strain value corresponding to the first rule and the stress-strain threshold corresponding to the first rule includes:

[0057] If the measured stress-strain value corresponding to the first rule is greater than or equal to the stress-strain threshold corresponding to the first rule, the seismic performance level is determined to be the first level;

[0058] If the measured stress-strain value corresponding to the first rule is less than the stress-strain threshold corresponding to the first rule, the measured pipeline centerline parameters of the pipeline to be detected, the seismic parameters corresponding to the seismic type of the target pipeline, the steel pipe specification parameters, and the welding process parameters are substituted into the stress-strain function corresponding to the second rule to obtain the measured stress-strain value corresponding to the second rule, and the seismic performance level is determined based on the measured stress-strain value corresponding to the second rule and the stress-strain threshold corresponding to the second rule.

[0059] In this embodiment, the pipeline seismic performance detection method should be consistent with the design document of the pipeline to be detected: When the design document adopts the strain-based design method, the strain method should be used to detect the seismic performance of the pipeline to be detected, that is, to verify that the strain of the pipeline under the action of the active fault meets the requirement of the allowable strain; when the design document adopts the stress-based design method, the stress method should be used to detect the seismic performance of the pipeline to be detected, that is, to verify that the stress of the pipeline under the action of the active fault meets the requirement of the allowable stress.

[0060] In this embodiment, according to the design document, a stress function and / or a strain function consistent with the design document are selected. The strain value and / or stress value of the pipeline under the action of an active fault: When the design document calculates the strain value and / or stress value of the pipeline under the action of an active fault by an analytical method, the analytical method in the corresponding standard specifications should also be used for calculating the strain value and / or stress value during the seismic performance detection of the pipeline, and the analytical formula should be the formula in the corresponding standard specifications. When the design document calculates the strain value and / or stress value of the pipeline under the action of an active fault by the finite element method, the finite element method should also be used for calculating the strain value and / or stress value during the seismic performance detection of the pipeline, and the establishment of the finite element model should meet the requirements of the corresponding standard specifications.

[0061] In this embodiment, the seismic performance of the pipeline needs to be detected by using the current standard specifications and the construction period standard specifications respectively. That is to say, the measured stress and strain values corresponding to the current standard specifications and the measured stress and strain values corresponding to the construction period standard specifications need to be calculated by using the stress and strain functions corresponding to the current standard specifications and the construction period standard specifications respectively.

[0062] In this embodiment, the stress and strain function corresponding to the second rule can be determined based on the construction period standard specifications, and the construction period standard specifications can include: Code for Seismic Design of Steel Oil (Gas) Pipelines, Code for Seismic Design of Steel Oil (Gas) Pipelines, and Technical Code for Seismic Design of Oil and Gas Pipeline Line Projects. In this embodiment, if the seismic performance level is the first level, it is determined that no rectification of the pipeline seismic measures is required.

[0063] In this embodiment, substituting the measured pipeline centerline parameters of the pipeline to be detected, the seismic parameters corresponding to the target pipeline seismic type, the steel pipe specification parameters, and the welding process parameters into the stress and strain function corresponding to the second rule, obtaining the measured stress and strain value corresponding to the second rule, and the method for determining the seismic performance level according to the measured stress and strain value corresponding to the second rule and the stress and strain threshold corresponding to the second rule can be: querying the design document to obtain the stress and strain function and the stress and strain threshold corresponding to the construction period standard specifications, and using the stress and strain function corresponding to the construction period standard specifications as the stress and strain function corresponding to the second rule, and using the stress and strain threshold corresponding to the construction period standard specifications as the stress and strain threshold corresponding to the second rule.

[0064] Optionally, determining the seismic performance level according to the measured stress and strain value corresponding to the second rule and the stress and strain threshold corresponding to the second rule includes:

[0065] If the measured stress and strain value corresponding to the second rule is greater than or equal to the stress and strain threshold corresponding to the second rule, it is determined that the seismic performance level is the second level;

[0066] If the measured stress-strain value corresponding to the second rule is less than the stress-strain threshold corresponding to the second rule, the seismic performance level is determined to be the third level.

[0067] In this embodiment, the measured stress-strain value may include: the measured stress value and / or the measured strain value. The stress-strain threshold may include: the measured stress threshold and / or the measured strain threshold.

[0068] In this embodiment, if the measured stress-strain value corresponding to the first rule is greater than or equal to the stress-strain threshold corresponding to the first rule, it is determined that the test passes based on the current standard specifications, and there is no need to determine whether the test passes based on the construction period standard specifications. The seismic performance level is directly determined to be the first level. That is to say, under the condition that the test passes based on the current standard specifications, regardless of whether the test passes based on the construction period standard specifications, the seismic performance level is grade I, that is, no rectification is required. If the measured stress-strain value corresponding to the first rule is less than the stress-strain threshold corresponding to the first rule, it is determined that the test fails based on the current standard specifications. In the case where the test fails based on the current standard specifications but passes based on the construction period standard specifications, the seismic performance level is determined to be grade II, that is, rectification is scheduled; in the case where the test fails based on the current standard specifications and also fails based on the construction period standard specifications, the seismic performance level is determined to be grade III, that is, rectification is required within a time limit.

[0069] Optionally, it further includes:

[0070] If the seismic performance level is the second level, the reminder time is determined according to the current time and the first time length;

[0071] If the seismic performance level is the third level, the reminder time is determined according to the current time and the second time length, where the second time length is less than the first time length.

[0072] In this embodiment, if the seismic performance level is the third level, the seismic measures need to be rectified within the specified time limit. If the seismic performance level is the second level, the seismic measures need to be rectified at a scheduled time. That is, in the case where the seismic performance level is the third level, the seismic measures need to be rectified as soon as possible to ensure the safety of the pipeline.

[0073] Optionally, the measured pipeline centerline parameters include at least one of the measured pipeline centerline position, the measured position of the pipeline crossing the active fault, the measured position of the hot-bent pipe, the measured direction, the measured angle, and the measured curvature radius. The seismic parameters corresponding to the seismic type of the target pipeline include at least one of the measured physical performance parameters of the backfill material, the type of smooth coating layer, and the thickness of the smooth coating layer. The backfill material is sampled at the intersection of the pipeline to be detected and the active fault within a preset distance range on both sides of the centerline of the pipeline to be detected. The steel pipe specification parameters include the measured wall thickness and / or the measured pipeline mechanical parameters. The welding process parameters include the measured welding type and / or the measured weld mechanical parameters. The anticorrosion layer parameters include at least one of the measured anticorrosion layer type, the measured anticorrosion layer thickness, and the measured adhesion of the anticorrosion layer.

[0074] In this embodiment, the seismic type of the target pipeline may be the type of seismic fortification measures for the pipeline. For example, the seismic type of the target pipeline includes at least one of the trench replacement measure type, the wide and shallow trench measure type, and the smooth coating layer engineering measure type.

[0075] In this embodiment, when the seismic type of the target pipeline is the trench replacement measure type, the seismic parameters corresponding to the seismic type of the target pipeline include the scope of the trench replacement measure and the measured physical performance parameters of the backfill material. Specifically, the method for obtaining the seismic parameters corresponding to the seismic type of the target pipeline may be as follows:

[0076] I. Combine the design documents to determine the scope of the trench replacement measure along the axial direction of the pipeline.

[0079] IV. When using other materials other than soil and sand for trench replacement, the physical and mechanical properties of the backfill material should be reviewed according to the relevant parameter content in the design documents.

[0080] V. Samples should be taken within 1 m on both sides of the pipeline centerline. When sampling, interference and damage to the pipeline should be avoided.

[0081] VI. The backfill material samples should be kept in their original state when sampling.

[0082] VII. The number of sampling points should not be less than 2, and the number of samples at each point should not be less than 6 groups.

[0083] VIII. For the obviously unreasonable data in the test materials, the reasons shall be analyzed (such as the representativeness of the specimens, abnormal situations during the test process, etc.), and the unreasonable data shall be discarded. When the test data do not meet the requirements of statistical analysis, the sampling quantity shall be increased and the test data shall be rechecked.

[0084] IX. It is necessary to recheck the buried depth of the pipe top.

[0085] In this embodiment, when the seismic type of the target pipeline is the wide and shallow pipe trench measure type, the seismic parameters corresponding to the seismic type of the target pipeline include: the scope of adopting the wide and shallow pipe trench measure, and the measured physical performance parameters of the backfill material. Specifically, the method for obtaining the seismic parameters corresponding to the seismic type of the target pipeline can be:

[0086] I. In combination with the design documents, determine the scope of adopting the wide and shallow pipe trench engineering measure along the axial direction of the pipeline.

[0087] II. Near the intersection point of the pipeline and the active fault, excavate a trench in the direction perpendicular to the axial direction of the pipeline to explore the boundary, size and buried depth of the pipe top of the wide and shallow pipe trench.

[0088] III. Near the intersection point of the pipeline and the active fault, take samples of the backfill material for rechecking the physical and mechanical parameters, including: ① Determine the type of the backfill material through soil classification tests (including particle analysis test, liquid-plastic limit test, etc.); ② Determine the unit weight of the backfill material through the unit weight test; ③ Determine the cohesion and internal friction angle of the backfill material through direct shear test (quick shear), triaxial shear test, etc.

[0089] IV. Samples shall be taken within 1 m on both sides of the pipeline center line, and interference and damage to the pipeline shall be avoided during sampling.

[0090] V. The original state shall be maintained during sampling of the backfill material.

[0091] VI. The number of sampling points shall not be less than 2, and the number of samples taken at each point shall not be less than 6 groups.

[0092] VII. For the obviously unreasonable data in the test materials, the reasons shall be analyzed (such as the representativeness of the specimens, abnormal situations during the test process, etc.), and the unreasonable data shall be discarded.

[0093] When the test data do not meet the requirements of statistical analysis, the sampling quantity shall be increased and the test data shall be rechecked.

[0094] In this embodiment, when the seismic type of the target pipeline is the smooth coating measure type, the seismic parameters corresponding to the seismic type of the target pipeline include: the scope of adopting the smooth coating measure, the type of the smooth coating and the thickness of the smooth coating. Specifically, the method for obtaining the seismic parameters corresponding to the seismic type of the target pipeline can be:

Specifically, the method for obtaining the measured pipeline center line parameters can be as follows:

[0099] Conduct on-site pipeline center line measurement, and the measurement range is the pipeline center line within the seismic fortification area:

[0100] 1. Mark the line position. Use equipment such as Radiodetection to preliminarily detect and mark the pipeline line position and orientation on the ground, and the marking should be densified at the pipeline orientation change points.

[0101] 2. Excavate exploration pits. Combine the design documents and the Radiodetection results to excavate exploration pits on the pipeline to accurately obtain the pipeline center line coordinates. The exploration pit positions should be set at the pipeline orientation change points and the pipeline elevation change points to accurately obtain the pipeline center line coordinates and describe the pipeline center line position. If there is a hot bend compensation structure within the range, exploration pits should be arranged at the hot bend compensation structure to accurately obtain information such as the position coordinates, direction, angle, and curvature radius of the hot bend.

[0102] 3. Measure the coordinates. Use equipment such as total station to measure the pipe top coordinates at the exploration pit positions, and the horizontal coordinates and elevation coordinates should be measured.

[0103] 4. Recheck the line position. Compare the measured pipeline coordinates with the design documents.

If there is a hot bend, it is also necessary to recheck whether the position, direction, angle, and curvature radius of the hot bend meet the requirements of the design documents. In the case where there is no hot bend and the pipeline center line coordinates, the position and angle of crossing the active fault both meet the requirements of the design documents, obtain the measured pipeline center line position and the measured position of crossing the active fault. In the case where there is a hot bend and the measured pipeline center line coordinates, the measured position and angle of crossing the active fault both meet the requirements of the design documents, and the measured position, measured direction, measured angle, and measured curvature radius of the hot bend also all meet the requirements of the design documents, obtain the measured pipeline center line position, the measured position of crossing the active fault, the measured position of the hot bend, the measured direction, the measured angle, and the measured curvature radius.

[0105] 1. Recheck the wall thickness of steel pipes using equipment such as ultrasonic thickness gauges, including the wall thickness of straight pipes, cold-bent pipes, and hot-bent pipes within the seismic fortification range of the pipeline.

[0106] 2. According to documents such as the quality certificate of steel pipes, query the physical and mechanical properties of steel pipes, including stress-strain curves, yield strength, tensile strength, yield ratio, uniform elongation rate, etc.; when using a strain-based design method, mechanical property parameters in the longitudinal direction (i.e., the axial direction) of the steel pipe should be obtained.

[0107] Compare and analyze the steel pipe specification parameters and the steel pipe data in the design document. When the requirements of the design document are met, obtain the measured wall thickness and / or the measured pipeline mechanical parameters.
