摘要/Abstract

摘要： 随着海上油气资源开发规模不断扩大，国内海洋油气田或将大规模采用水下井口生产模式，而国内还未有与之配套的水下修井装备和技术。本文对比了国际上现行主流的两种修井作业技术，着重介绍了两种轻型修井作业系统及其优缺点，对国外现有的水下修井装备发展和作业情况进行了分析。最后归纳总结了国内相关技术的发展差距和应对策略。

Abstract:

As the continuous expansion of the resources development of offshore oil and gas, more subsea well will be used at domestic offshore oil and gas fields, yet there is still no supporting technology and equipment for subsea well intervention in China. This paper compare the technology of well intervention and workover, introduce two kinds of light well intervention systems, compare their advantages and disadvantages, and then analyze the development and operation of subsea well intervention systems in the world. The development gap and countermeasures of related technologies in China will be summarized, at the end.

Key words: Subsea Well, Well Intervention, Workover
