Located in the Sichuan Basin, the Yuanba Gasfield is the deepest marine bitter gasoline discipline amongst these developed in China so far. Its biohermal fuel reservoir of the Upper Permian Changing Fm is characterized with the aid of extremely depth, excessive content material of hydrogen supplied, medium–low porosity and permeability, and small reservoir thickness. Economic comparison on it suggests that horizontal properly drilling is the solely way to increase this fuel reservoir correctly and to limit the complete improvement investment. At present, the petroleum engineering technological know-how for this kind of ultra-deep bitter gasoline reservoir is much less utilized in the world, so an ultra-deep horizontal properly is concern to a sequence of petroleum engineering science difficulties, such as protected and quick nicely drilling and completion, mud logging, nicely logging, down hole operation, security and environmental protection.
