摘要

管道是石油、天然气等能源介质相对安全的主要运输方式，但由于原油管道铺设距离较长，内部流质环境复杂，且输送的介质具有一定的腐蚀性，导致原油管道内腐蚀泄露事故时有发生，严重影响了管道的日常生产管理。管道内腐蚀在线监测，是即时、准确获取管道内腐蚀状况，保证原油管道安全运行的有效手段。研究原油管道腐蚀类型及机理可为在线监测技术的改进提供良好的参考。本文针对原油管道的内腐蚀类型、机理以及目前应用较为广泛的管道内腐蚀监测技术进行了论述，分析对比了多种管道内腐蚀在线监测技术的优缺点以及应用情况，对输油管线内腐蚀在线监测技术的选择、改进及发展前景提出了展望，指出未来管道内腐蚀在线监测技术将向智能化、自动化和远程监控的方向发展，为相关科研人员及企业进行现场创新应用提供了有价值的参考资料。

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.
