摘要
海洋油气井水下井口回接是海洋油气井通过水下井口与海面采油平台建立采油采气通道的一种方法。介绍了回接连接装置的结构、组合式金属膨胀密封环的设计方案及其工作原理。该方案设计的装置结构简单、操作方便,为国内在海上油气井回接系统方面的研究提供新的设计思路。
Subsea wellhead tieback device is used to establish the channel which enables the oil or gas to be brought from subsea wellhead to production platform.The paper firstly introduces the structure of subsea wellhead tieback device and the design of expandable combined metal seal ring,and then discusses about working principle of the designed device.The designed subsea wellhead tieback device is simple in structure,easy to operate,and can provide a new design concept for domestic R ＆ D of tieback system.
