我国海上低渗油气田开发钻完井技术研究

The Development Technique Exploration of Drilling and Completion for China Offshore Oil and Gas Field

我国海上低渗透油气田储量规模庞大,但一直得不到经济有效的开发,其主要原因是海上油田开发成本较高,单井产能较低。受作业条件限制,海上低渗油气田开发仅通过移植陆地油气田开发模式,很难获得成功。分析我国海上现有开发模式在低渗油藏开发中存在的问题和难度,提出经济有效地开发海上低渗储层钻完井工程需具备的技术要求。针对目前存在的问题,提出钻完井技术研究思路,并介绍了近年来所取得的部分成果。

China offshore oil and gas reserves with low permeability is in large scale, but it can not be developed well. Because the offshore oilfield development cost is too high, but the production is low. If we use the land oil field development experience, it will be difficult to achieve the successful development of the low permeability reservoir. This paper analyzes the problems and difficulty in existing development mode for low permeability reservoir development, puts forward economic development on low permeability reservoir of well drilling and completion engineering with technical requirements. This paper also puts forward the technology research direction of drilling and completion, and introduces the achievement in recent years.
