Guided by the subjects of Sedimentology, Reservoir Geology and Logging Geology, this paper is making full use of the intensive drilling, logging, testing and the dynamic developing data to define the types of sedimentary facies of the target intervals such as He-8 Member and Shan-1 Member in the central Sulige Gasfield over the study of facies marks. Based upon the analysis of the core and gas testing datum, the log interpretation model of the target intervals was set up to identify the effective reservoirs accutrately, and the detailed interpretation of logging datum from nearly 2000 wells in this region was carried out. Hence, related to the drilling and dynamic production datum, the distribution rule of sand body and effective sand body were pointed out; the planes of sedimentary facies were drawn and the sedimentary model in this area was built up. Then the fine description of the sand body and reservoir modeling in the area of the dense well pattern has been carried on, and the main controlled factors to the distribution of high-quality reservoir have been pointed out. In order to provide technical support for high-efficiency development in the central Sulige Gasfield, it is significant to set up a comprehensive reservoir evaluation system and criteria.
