摘要:

针对油气管道采用机械管卡进行临时堵漏时，停输工艺施工周期长，对下游影响大，而不停输封堵工艺施工风险大、费用高的问题，提出了海底管道隔离套筒法修复技术，隔离套筒严格按照国内外标准规范设计，并采用有限元方法校核所有应力集中点，通过理论研究和模拟试验，证实其为一种安全可靠的在役管道维修技术。将该技术应用于番禺 30-1 海底管道的局部泄漏，修复期间保留原有管卡，而且无需管道停输。该项技术的成功应用进一步提高了国内海底管道的在线维修技术水平。

Abstract:

When mechanical pipe clamp is used to temporarily plug the leak, the operation with shutdown is time-consuming and has great impacts on downstream pipeline, while the operation without shutdown is risky and costly.In this regard, the isolated sleeve remediation technology of subsea pipeline is proposed.It is designed in strict compliance with domestic and international standards and all stress concentration points are checked using the finite element method.Through theoretical research and simulation experiment, the isolated sleeve is proved as a safe and reliable remediation technology for in-service pipeline.The technology is successfully applied to local leak of Panyu 30-1 subsea pipeline.During the operation, original pipe clamp is retained and the pipeline is shutdown.The technology helps to improve the on-line maintenance of domestic pipelines.
