In order to provide theory gist for exploration zone optimization and well placement, the zoning and segmentation characteristics and different control factors of reservoir in Bashijiqike Formation in Keshen area were studied with logging, core, casting thin section, confocal laser scanning and other available data by means of discrete element stress numerical simulation. The results show that there are obvious zoning features bounded by Keshen 8 fault in reservoir physical property and pore throat structure. In the north of the fault, the buried depth of the reservoir is mostly between 6000 m and 7400 m, with the effective porosity mainly distributed between 4.0% and 12.0%, and type-?and type-? pore throat structure predominant. However, in the south of the fault, the buried depth of the reservoir is mostly between 7400 m and 8000 m, with the effective porosity mainly distributed bet.. View more»
