Abstract: The Baiyinchagan sag is a secondary structural unit of Erlian basin. Based on a lot of geologic, seismic and drilling data, this paper presents the structural and sedimentary evolution history of it and makes a classification of five stages by which its structural framework and sedimentary characteristic are controlled. In Bayanhua group of the Lower Cretaceous in this sag there exist 3 sets of source rocks and 2 sets of reservoirs. They are connective in plane and overlapped in vertical, thus providing good conditions for petroleum secondarymigration and accumulation here
