Abstract
Geology steering technology is one of core technologies available for shale gas development. The geologic responses such as gamma, resistivity, drilling time ratio etc 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.关键词
