Abstract

Pipeline is a relatively safe major transportation mode for oil，natural gas and other energy media，but due to the long laying distance of crude oil pipelines， the complexity of the internal fluid environment， and the fact that the transportation medium has a certain corrosiveness，corrosion leakage accidents occur frenquenfly in crude oil pipelines， which seriously affects the daily production management of pipelines.Online monitoring of pipeline internal corrosion is an effective means to obtain the corrosion status of pipeline immediately and accurately and ensure the safe operation of crude oil pipeline.The study of corrosion type and mechanism of crude oil pipeline can provide a good reference for the improvement of on-line monitoring technology.This paper discussed the types and mechanisms of internal corrosion in crude oil pipelines as well as the widely used pipeline internal corrosion monitoring technologies， analyzed and compared the advantages and disadvantages of various online pipeline corrosion monitoring technologies and their application scenarios.Furthermore， the prospects for the selection， improvement and development of online pipeline corrosion monitoring technologies were put forward.In general， it’s pointed out that the online monitoring technology of pipeline internal corrosion will develop in the direction of intelligence， automation and remote monitoring in the future， which provided valuable references for relevant researchers and enterprises to carry out on-site innovative applications.

Key words： oil pipeline; internal corrosion; corrosion mechanism; on-line monitoring; prospects
