Abstract: As oil and natural gas contain a lot of corrosive components during gathering process, they will cause corrosion, such as perforation and grooves, etc., so as to ensure the safety of gathering pipelines, it is necessary to detect corrosion defects. Based on the remote-field eddy current detection principle, the remote-field eddy current simulation model based on the gathering pipeline is established. Through the analysis of the influence of the pipeline defect on the amplitude and phase of the magnetic induction axial component, the ralationship of the depth of the inner wall defect and the corresponding detection signal is obtained. The relationship solves the quantitative measurement of the depth of the defect.
