摘要
为进行万米特深层地球科学探索和油气勘探,实现特深钻井工程技术的迭代升级,中国石油天然气集团有限公司2023年在塔里木盆地部署了万米特深井深地塔科1井。通过该井的成功钻探,地质认识方面取得突破性进展,首次获取了万米深层岩心、测井、录井、流体、温度及压力资料,认识到万米特深层仍发育有效烃源岩、碳酸盐岩储层及可动常规油气,打破了传统的油气地质理论认识,明确了塔里木盆地万米特深层油气勘探的巨大潜力并指出了有利勘探领域。工程技术方面形成了特深井复杂压力系统安全钻井、特深井复杂难钻地层优快钻井、特深井苛刻工况井筒质量控制、特深超高温复杂地层资料录取4大关键技术体系。同时铸就了特深钻完井工程技术十大利器,顺利成功完钻了亚洲第1、全球第2垂直深井,极大促进了对万米特深层地质条件的认识,助力中国成为具备特深井钻探核心技术的少数国家。
In 2023,the China National Petroleum Corporation(CNPC)has successfully drilled a 10000-m ultra-deep well–TK-1 in the Tarim Basin.This pioneering project has achieved dual breakthroughs in ten-thousand-meter ultra-deep earth science research and hydrocarbon exploration while driving technological advancements in ultra-deep well drilling engineering.The successful completion of TK-1 has yielded transformative geological discoveries.For the first time in exploration history,comprehensive data including cores,well logs,fluids,temperature and pressure were obtained from 10000-meter depths.These findings conclusively demonstrate the existence of effective source rocks,carbonate reservoirs,and producible conventional hydrocarbons at such extreme depths–fundamentally challenging established petroleum geology paradigms.The results not only confirm the enormous hydrocarbon potential of ultra-deep formations in the Tarim Basin but also identify the most promising exploration targets.From an engineering perspective,the project has established four groundbreaking technological systems:safe drilling in complex pressure systems of ultra-deep wells,optimized and fast drilling in complex and difficult-to-drill formations of ultra-deep wells,wellbore quality control under harsh conditions in ultra-deep wells,and data acquisition in ultra-deep,ultra-high-temperature complex formations.Additionally,ten key tools for ultra-deep well drilling and completion engineering were developed,enabling the successful completion of Asia’s first and the world’s second-deepest vertical well.This achievement has significantly advanced the understanding of geological conditions at depths exceeding 10000 m and positioned China as one of the few countries with core technologies for ultra-deep well drilling.
