摘要：地质乎向技术是开发页券气的核心技术之一，分析了页岩气储层份马、电阻率、钻时比值等地质特征响应，结合
用FEWD地质导向技术提高页岩气水平井储层钻遇率的关键。丁页2HF并创造了越深页岩气井复合钻日进尺最高178m的记录，仅用55d完成1035m的水平段钻探，水平段储层钻遇率达95%。FEWD地质导向技术在丁山深层页岩气水平井的成功运用，促进了页岩气非常规能源的开发，对今后国内超深页岩气水平井的钻井施工具有重要的指导意义

Abstract: Geology steering technology is one of core technologies available for shale gas development. The geologic responses such as gamma, resistivity, drilling time ratio etec of'shale gas reservoirs have been analyzed in the paper, in light of the features of FEWD geology steering technology, its advantages in drilling horizontal wells for shale gas development in deep layers have been pointed out By a case study of Well Dingye 2HF, the keys in enhancing drilling rate of reservoir formations in horizontal wells with FEWD geology steering technology have been demonstrated. Well Dingye 2HF set the record of drilling 178 m in one day for super-deep shale gas wells and its horizontal interval of 1 035 m was completed in only 55 d, and its reservoir drilling rate of the horizontal interval is up to 95% Successful application of FEWD geology steering technology in horizontal wells for shale gas development in deep Dingshan Formation can effectively promote development of unconventional shale gas, and provide valuable guidance for drilling horizontal wells for shale gas development in super deep formations in China

页岩气储集层的勘探开发最早始于美国，目前已成为国内非常规气藏勘探开发的重点和热点1。为便于后续压裂开发，页岩气勘探开发主要以水平
并为主，且在开发过程中探井相对较少，对储层的认识不足；另外，由于岩性和储层物性的不同，钻并过程中，利用传统的砂岩和碳酸盐岩油气层录井评价
