The southern Yanchuan area is situated at the junction of Jinxi flexural folded zone and Weibei uplift, southeast margin of the Ordos Basin. During the gas tests of two wells in the area have obtained medium to high yield gas flow in the sixth and eighth mem-bers of the Xiashihezi Formation. Based on previous studies, analyzed the formation’s compact sandstone reservoir sedimentary facies type, accumulating spatial characteristics, reservoir physical property and main controlling factors to impact gas reservoir development, considered that the gas producing horizon in the formation is generally developed in the channel bar microfacies of river sand mass en-richment zone, reservoir rock type is mainly feldspar lithic quartz sandatone, lithic sandstone and lithic quartz sandstone the second. The channel sand mass enrichment zone in the area is covered by mudstone on top and blocked by reversed faults laterally, thus formed the lithologic-stratigraphic composite gas reservoir.
