摘要

基于荔湾3-1气田周边的油气田深水管道情况,分析深水环境因素对管道失效的影响。具体给出三种深水海管失效形式,并提出相应失效模式下的维修方法,着重介绍不同维修方法的维修流程和核心维修工具资源。在此基础上,分析不同方法的优缺点,并探讨它们在荔湾周边的应用可行性。螺栓型管卡维修和连接器在底维修可作为我国深水海管维修的重点发展方向。

Abstract：

The special environment conditions of oil and gas fields near Liwan 3-1 are introduced with their adverse effects on pipelines, and three damage scenarios of deepwater pipeline for repairing damaged pipeline are listed. According to the damage scenarios, methods for repairing damaged pipeline in deep water are summarized with repair procedure and equipment, and those methods are compared. Finally, the application possibility of all methods for pipeline repair in deepwater field is analyzed. It is concluded that repair with bolted clamp or connector can be main repair methods for deepwater pipelines in China.

Key words： deepwater pipeline damage scenarios of pipeline pipeline repair repair procedure
