摘　　要：大量地震、录井、测井资料沉积学分析表明,松辽盆地北部西部断陷带登娄库组三段发育的沉积体系有扇三角洲、湖泊和湖底扇。在平面上,靠近沉积东侧边界和西侧边界奋发育5个和3个裙带状扇三角洲沉积体系,扇三角洲沉积区之间的中央部位为大片的湖泊体系沉积。水体相对较深处为浅湖沉积,其余为滨浅湖沉积。浅湖沉积物中央有湖底扇粗粒沉积物。这一沉积特征展示了松辽盆地北部西部断陷带登娄库组三段储层十分发育,具有良好的油气勘探前景。Based on a large number of core, logging and seismic data, and adopted the newest methods of sedimentology, the third member of Denglouku Formation in western fault belt of the northern Songliao Basin can be classified into fan delta depositional system, lacustrine system, and lake-floor fan system. There are 5 and 3 fan-delta depositional systems developed respectively along the western and eastern margin fault. In the central area between fan deltas, lacustrine system was developed, beach and shallow lake deposits were developed very well in deep zone, the lake-floor fan system developed in the shallow lake area. These sedimentary characteristics show the favorable condition of reservoir rock and the favorable potential of oil and gas exploration.
