%X As the south part of Songliao Basin,Changlin depression have abundant resource of oil and gas.At present,Changlin depression have already been developed.The depression have many layers of oil and gas accumulation,which have many different types of accumulations.It is those good geological conditions that was favourable to development of complex accumulation of oil and gas.This paper will report the development regularity of oil and gas accumulation in Changlin Depression,and analyze log and seismic data by seismic attribution and log-restrict inversion to forcast reservoir in the depression,in order to find distribution characteristic of advantageous reservoir and sandstone bodies,and to understand the relationship between sandstone body and faults,vanished character of sandstone body and identify the closure of lithological character.The results show that,characteristic of oil and gas accumulation mainly have three types of closure,such as complex strcuture-lithological closure,upper-dip tail-out closure of sandstone body and len closure of sandstone body.The development regularity of oil and gas accumulation mainly is multi-layer of oil and gas and mutual effect of those sandstone groups.And,single accumulation have too small area,but widely distributed as sheet in the horizontal plane.Multi-sandstone-body in the accumulation have vertical connexity.The main objective-layer,such as sandstone layers in Qing-I and Qing-II formation,have main characteristic of delta front watercourse,which is north-eastern trend.And,faults in this area have nearly south-eastern to north-western strike,which is perpendicular to those sandstone bodies.Those relationship easily result in the development of the complex closure of structure-lithology.
