摘　　要：依据大量地质、地震和钻井资料,再现了二连盆地白音查干凹陷构造沉积演化史,将其构造沉积演化划分为5个阶段,并认为不同演化阶段控制了凹陷的构造格局和地层沉积特征。凹陷下白垩统巴彦花群发育3套烃源岩和2套储集岩,烃源岩与储集岩平面上相互衔接,纵向互相叠置,为油气二次运移及聚集成藏提供了良好的条件。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 secondary migration and accumulation here.
