中国石化海外油气田钻井完井技术现状与发展建议

Drilling & Completion Technologies of Sinopec Overseas Oilfields:Status Quo of Technology & Development Suggestions

中国石化海外油气田年权益油气产量当量已超过4 000×10~4 t,成为我国油气能源供应安全的重要保障。钻井完井工程技术是实现中国石化海外油气勘探开发目标的关键,国际油气市场新形势和中国石化海外资源分布新格局给钻井完井工程技术发展提出了新要求。为此,总结了近年来中国石化各海外区块钻井完井工程技术主要进展,分析了目前海外油气田钻井完井技术存在的问题和面临的挑战,并建议以持续推进技术创新策略应对油价低位震荡,通过"瓶颈"技术攻关、成熟技术集成应用、基础研究和技术储备、技术管理体系建设,加快中国石化海外油气田钻井完井工程技术发展,实现海外油气田勘探开发中的挖潜增效。

The yearly oil&gas production from Sinopec overseas fields has exceeded 4 000×10 4 t,which has become an important guarantee for the safety of oil and gas energy supply in China.Drilling&completion engineering plays a key role in achieving Sinopec overseas oil and gas exploration and development targets.The continual fluctuation within the international oil and gas market environment and the new Sinopec overseas resources distribution pattern have put forward new requirements for the development of drilling&completion engineering.Therefore,this paper summarizes primary progress in drilling&completion engineering achieved in Sinopec overseas fields in past years,and it analyzes existing problems and challenges.Finally,it proposes development suggestions.It proposes to take the strategy of continuously promoting technology innovation to deal with oil price fluctuations,and to accelerate the development of drilling&completion technology and realize potential resource tapping and efficiency improvement by tackling“bottlenecks”,integrative applications,basic research and technology development of reserves,and the construction of a technical management system.
