Abstract: The application of eddy current internal inspection technology can effectively evaluate the distribution and depth of defects in offshore oilfield oil pipelines,and provide a data basis for oil pipeline management decisions,which is conducive to formulating targeted management measures and improving the management efficiency of offshore oilfield oil pipelines. Based on eddy current internal inspection data,the distribution and depth of defects in an offshore oil pipeline are systematically analyzed,the remaining strength and remaining life are evaluated,and conclusions and suggestions are provided. The results of field experiments indicate that the accuracy of eddy current internal inspection data is high,which has guiding significance for the integrity management of oil pipelines in offshore oilfields.

Key words: crude oil pipeline corrosion, eddy current inspection, pipeline corrosion, pipeline defect
