Abstract

Through the combination of sedimentological and geochemical analyses, characteristics and distribution rules of the Paleogene source rocks of Lower Es4,Upper Es4 and Lower Es3 Members are analyzed in this paper.Then the physical properties,group compositions and biomarker features of the discovered oils in red rocks are further studied.The oils in the red rocks can be divided into different types.On the basis of oil-source correlation,the origins of the oils are determined.The results show that not only Upper Es4 and Lower Es3 Members,but Lower Es4 Member which was poorly understood in the past make great contributions to oil formation in red rocks.It can be concluded that Paleogene red rocks in the Dongying sag have great exploration potential.They will be the major areas for reserve and production increase in the near future.
