In order to make a detailed and in-depth study of the sedimentary facies in this area, with the help of the theories of sedimentology, petroleum geology and Geophysics, combined with the regional geological data, core, thin section and logging data, and based on the collection, comprehensive analysis and summary of the existing results, this paper discusses the sedimentary microfacies types and spatial distribution characteristics of Shan 1 member of Permian Shanxi Formation in the East second area of Sulige gas field. The study shows that the sedimentary facies types of Shan 1 member in the study area mainly include braided river facies and meandering river facies. Meandering river deposits are mainly developed in Shan 1 member; It mainly develops sedimentary microfacies such as oxbow lake, floodplain, crevasse fan and edge beach sedimentation.
