Pipeline integrity assessment is one of the core parts of pipeline integrity management,among which the in-line inspection and as-sessment method is one of the three basic methods for pipeline integrity assessment.The development of in-line inspection technology in oil and gas pipelines plays a vital role in ensuring the safety of oil and gas pipelines.Based on the analysis of data dimensions and visual analy-sis of clustering,co-occurrence and emergence knowledge graphs of relevant literature on oil and gas pipeline inspection technology from 1990 to 2022,the development history and achievements of in-line inspection technology over the past 30 years were elaborated,and the fu-ture development trend was predicted,which was intended to provide inspiration for the related work of in-line inspection technology in Chi-na.The main conclusions are that the research of in-line inspection technology in China has gone through the stage of initial germination and rapid development,and is currently in the stage of stable development,and this trend will continue for a long time.The research in-line in-spection technology mainly focuses on the innovation research and development of pipeline inspection gauge(PIG)such as magnetic flux leakage(MFL),ultrasonic testing(UT),eddy current(EC),etc.,as well as data processing.
