定向钻井技术引领 聚焦深地深海探测——勘探技术所“十三五”科技创新回顾及“十四五”业务展望

Directional drilling technology takes lead with focus on deep earth and deep sea exploration—Review of science and technology innovation by Institute of Exploration Techniques,CAGS during the 13th Five‑Year Plan and an outlook to the 14th Five‑Year Plan

全面总结了中国地质科学院勘探技术研究所“十三五”期间在定向钻井技术及仪器、深部钻探技术与装备、海洋钻探技术与装备等方面取得的重要成果,主要包括:创新突破定向水平井钻井及中靶技术,助力海域天然气水合物第二轮试采实现了从“探索性试采”向“试验性试采”的重大跨越;牵头实施完成“松科二井”重大科学钻探工程,实现了理论、技术、工程、装备的重大突破;成功研发了首套国产深海井口吸力锚,解决了深海浅软地层井口支撑力不足的难题。同时,分析了目前存在的问题,并结合当前所面临的挑战,对“十四五”期间的业务发展进行了展望。

This paper comprehensively summarizes the important achievements made by Institute of Exploration Techniques,CAGS on directional drilling technology and survey tools,deep drilling technology and equipment,offshore drilling technology and equipment during the 13th Five‑Year Plan.These achievements mainly include innovations in directional drilling and well intersection technology which has helped the second‑round offshore natural gas hydrate production test realizing a leap from“exploratory production test”to“trial production test”;organization and implementation of Well SK-2 scientific drilling project where significant breakthroughs have been made on theory,technology,engineering and equipment;development of the first domestic deep sea wellhead suction anchor which has solved the insufficient support problem with the wellhead in deep sea shallow soft stratum.Moreover,this paper also analyses the existing problems and challenges with an outlook made on the institute’s future research activities in the coming 14th Five‑Year Plan.
