中国海洋石油集团有限公司深水钻完井技术进展及展望

Progress and prospect of deepwater well drilling and completion technique of CNOOC

近年来,深水区域成为油气资源重要的潜力区与增长极。中国海洋石油集团有限公司(中国海油)在深水领域从跟踪学习、对外合作到自主创新,目前在西非、巴西、墨西哥湾均拥有深水权益区块,已安全高效完成40余口深水井钻完井作业,正在稳步推进中国首个自营深水气田的开发作业。中国海油已经掌握了深水钻完井系列技术,在深水隔水管、深水浅层安全高效钻井、深水测试和完井、深水井控及应急救援等方面形成了技术体系。面向未来,中国海油将聚焦深水高温高压、超深水、深水深井、深海天然气水合物等领域,进一步发展作业风险控制及安全应急技术,着力实现信息化、智能化、国产化,助推中国海洋石油工业走向更深、更远。

In recent years,deepwater areas have become important potential areas and growth poles for oil and gas resources.From tracking study,foreign cooperation to independent innovation,China National Offshore Oil Corporation(CNOOC)has made great progress in the deepwater field.Currently,it has deepwater blocks with corresponding rights and interests in West Africa,Brazil,and the Gulf of Mexico.Drilling and completion operations of more than 40 deepwater wells have been completed safely and efficiently.The development of the first self-operation deepwater gas field in China is being steadily advanced.CNOOC has mastered a series of deepwater well drilling and completion technologies,and has established a technical system involving deepwater risers,safe and efficient drilling in deepwater shallow layers,deepwater well testing and completion,deepwater well control and emergency rescue,and etc.Facing the future,CNOOC will focus on the fields such as high temperature and high pressure in deepwater zones,ultra-deepwater and deepwater wells,and deep-sea gas hydrates,further develop technologies for controlling operational risks and solving safe emergencies,strive to achieve informationization,intelligentialization and localization,and promote the further development of China’s offshore oil industry.
