The invention provides a method and a device for an oil and gas pipeline deformation detection verification test. The method comprises the following steps that a pipeline to be detected is fixed on a ground support, five lifting jack devices are installed in the middle of the pipeline to be detected, a pipeline inertial measuring device is installed on a pipeline deformation detecting device which is well designed, the pipeline deformation detecting device is pulled to pass through the pipeline to be detected, the pipeline inertial measuring device and an odometer arranged on an odometer wheel of the pipeline deformation detecting device automatically record detection data of the pipeline, the pipeline reaches a predetermined settlement amount of a certain length of a pipeline section by means of the self-weight of the pipeline and the lifting jack devices, the pipeline is pulled to pass through the settled and deformed pipeline, the pipeline settlement deformation and pulling test is repeated, accuracy and effectiveness of data are guaranteed, various kinds of speed are adopted for pulling every time the pipeline is deformed, results of multiple pulling tests are compared, and a pipeline deformation detection device performance verification pulling test is finished. The method and the device provide test data for detector calibration and performance index tests, and improve accuracy and reliability of pipeline integrity evaluation results.

Description

technical field [0001] The invention relates to an oil and gas pipeline deformation detection verification test method and device. It relates to the technical field of piping systems. Background technique [0002] Oil and gas pipeline deformation detection verification test is an important method for the verification of pipeline deformation detection performance indicators, and is the basis for analyzing and evaluating pipeline deformation detection data. The test results can provide basis and reference for pipeline detection and data analysis. [0003] With the development of oil and gas pipeline integrity technology, the requirements for the controllability of pipeline safety are getting higher and higher. It is not only necessary to fully grasp the defects of the pipeline itself, but also to identify the external influences on the pipeline. Especially in recent years, the movement of pipes caused by geological landslides, frost heaving and thawing, and pipeline excavatio...

Problems solved by technology

However, in its industrial application, there is still the problem of determining the performance index of deformation detection, especially the case that has not been successfully used in China. It is urgent to test and verify the performance index of deformation detection and perform calibration to solve the problem of pipe deformation detection.

[0004] CN101451812A discloses a pipeline deformation detection method, although it can detect the movement of the pipe body to a certain extent, but it is not ideal in determining the deformation detection performance index
