油气管道机械损伤的完整性研究进展

Progress in the integrity research of mechanical damage of oil and gas pipelines

机械损伤是导致管道事故的主要原因,对其进行完整性管理一直是管道业界的难题。基于国内外事故案例,介绍了管道机械损伤的危害性和特殊性。从评价技术、管理技术和标准规范3个方面回顾了国内外关于管道机械损伤完整性的研究历程,虽然取得一些进展,但迄今尚无一个权威性指南可供指导应用实践。分析了管道机械损伤在检测、识别、评价3个方面需要解决的技术难题,针对机械损伤完整性管理研究策略,提出了评估-缓解-预防研究路线图,给出了不同专题各个领域的重点研究内容。

Mechanical damage is the main reason led to pipeline accidents,and the integrity management on it has always been a difficult problem in the pipeline industry.Based on the pipelines' accident cases at home and abroad,the hazards and characteristics of pipeline mechanical damage are introduced.The research process in the integrity of pipeline mechanical damage worldwide is reviewed from evaluation technology,management technology and standards.Although some progress is achieved,so far there has been no authoritative guideline available to instruct the application practice.Technical problems to be solved in pipeline mechanical damage in detection,identification and evaluation are analyzed.For the research strategies in the integrity management of pipeline's mechanical damage,a research line diagram of 'assessment-mitigation-prevention' is proposed,and key contents in different research fields about special subjects of mechanical damage of pipelines are given.
