[Abstract]:In order to solve the problem caused by the huge amount of magnetic flux leakage detection data in oil and gas pipelines, a detection method for quickly identifying the target defect area to be solved from the magnetic flux leakage detection data is studied. Based on the finite element simulation calculation, the characteristics of 3D magnetic flux leakage detection signal of oil and gas pipeline are studied, and then the detection data are intercepted by segmented threshold, and a piecewise identification method of pipeline defect area to be solved is proposed, which can deal with massive data of magnetic flux leakage detection of oil and gas pipeline quickly and accurately. Based on the magnetic flux leakage detection data of actual oil and gas pipelines, the proposed piecewise identification method is tested and verified. The experimental results show that the proposed method can accurately identify the defect area on the pipeline, which not only contains the defect and its adjacent area, but also does not have excessive independent area, and can effectively control the amount of data in the subsequent processing process.
