摘要: 为推进长江下游地区页岩油气等清洁能源调查工作,2015-2021年中国地质调查局在安徽地区部署了25口页岩气井。针对勘探区域地质构造复杂、软硬互层、断层裂隙发育以及地层破碎等地质条件引起的恶性漏失、难钻进、难取心、井壁失稳等钻井复杂情况,通过制定针对性堵漏方案,优选多种类钻头,优化钻具组合、钻井液配置和钻井工艺,初步形成了长江下游(安徽)地区页岩气钻井技术体系,包括:破碎带高效高质取心工艺、软硬互层纠斜控斜钻具组合研究、强研磨性硬地层钻头优选、恶性漏失卡钻处理方法、水平井段钻井液堵漏技术以及水敏地层井壁稳定处理等。为该区后续钻井工程设计和施工作业提供有益借鉴。Abstract: To seek breakthroughs and discoveries in shale gas resource exploration in the lower reach of the Yangtze River, China Geological Survey deployed 25 shale gas wells in Aahui province from 2015-2021. In view of malignant leakage, difficult coring, difficult drilling and well wall instability due to complex geological conditions in the exploration area, including complex geological formations, soft and hard interbedding, fault development and broken formation, a shale gas drilling technology system has been developed for the lower reaches of the Yangtze River (Anhui) through the selection of multiple types of drill bits, optimization of drilling tool combinations, drilling fluid configuration and drilling techniques, The technology system includes high-efficiency and high-quality coring technology for the fracture zone, research on soft and hard interbedding deviation correction and control BHA, optimization of bits in strong abrasive hard formations, treatment methods for malignant leakage and sticking, drilling fluid plugging technology for horizontal well sections, and wellbore stability treatment in water sensitive formations. The research may provide beneficial reference for optimal well drilling design and drilling operations for shale gas survey.
