Abstract: A borefild in Sulige gas field, as the development experimental zone of this block, has built 1 billion square production after more than two years' pilot development. In this area， a set of effective thinking and method of research has formed about the fine geologic research. On the one hand, according to the characteristics of low porosity, low permeability and fluvial facies sand body developed, synthesizing all kinds of static and dynamic development data. The fine reservoir 3D visualized geological model was established and the areal channel sand body distribution was carved, which provide geological guarantee for the overall development of horizontal well and horizontal well geologic trace and implementation. Meanwhile, the regional distribution rule of remaining gas was gained, providing the reference for implementing horizontal wells step by step. On the other hand, based on unstructured grid used for depicting fracture system, through the gas reservoir numerical simulation, deployment parameters of horizontal well pattern, well spacing etc., are optimized and demonstrated, and reasonable values of parameters are gained, which provides reference to similar other fields for overall development.
