Abstract: By studying the distribution characteristics, lithologic assemblages, core features,grain size analysis and seismic reflectance of skeleton sandstone of D Ⅲ interval in Chaxi area,it is regarded that the reservoir sandstones was mainly the result of turbidity and the turbidite measure was connected with the whole event of the fault controlling sag—Niudong fault origin,evolution and extinetion. There are three turbidity fan (Xionggul-Cha39,Cha76 and Cha107-Xiong21)in the area by analysis. Because of late differential compaction,they belong to three structural nose respectively and all have gained commercial oil and gas. For the Sake of increasing reserves and production,they are the best area for the roll-over exploration.
