Abstract: The Sulige gas field occurs as a large-sized gas reservoir with sandstone traps in China. There has long been much debate concerning the sedimentary facies types. The authors in the present paper contend, on the basis of cores and well logs, that the eighth member of the Middle Permian Lower Shihezi Formation in the Sulige region should be assigned to the braided delta sedimentary system. The sedimentary facies plan is constructed for the deposition of the eighth member of the Middle Permian Lower Shihezi Formation, and the sedimentary facies model is proposed for the study area according to the spatio-temporal distribution of sedimentary facies.
