摘要
海底管道是海上油气田开发、生产与油气外输的主要生产设施 ,目前海洋石油总公司铺设的海底管道总长度已超过 2 0 0 0km ,进入 2 0世纪 90年代后 ,由于各种原因 ,如管道运行状态超出设计范围 ,船舶起抛锚作业 ,拖网捕鱼碰撞 ,海底冲刷以及施工操作不当 ,落物冲击 ,介质腐蚀等 ,相继出现海底管道损坏事故 ,其损坏形式多种多样。根据海洋石油总公司在役油气田海底管道的维修实践、海底管道损坏情况及海况特点 ,介绍几种海底管道维修方法 ,并对海底管道的安全运营提出建议。
It is known that subsea pipeline, as “the lifeline of oil and gas fields”, is the main facility for offshore oil and gas development, production and export. Now, the total length of subsea pipelines laid by CNOOC is more than 2000 km. But, since 1990s, some accidents of the subsea pipelines have occurred in various kinds of damages due to a lot of reasons, such as pipeline operation overriding design capacity, vessels anchoring, dragnet, washing out, error operation, heavy bumping, corrosion etc. In this paper, subsea pipeline repair technique and methods are introduced based on the pipeline repair practices of CNOOC and the characteristics of pipeline damage, and some advices are given on subsea pipeline working safety.
