本文通过沉积学和地球化学分析相结合，分析了沙四下、沙四上、沙三下古近系烃源岩的特征和分布规律，进而对已发现的红层原油的物性、族组成和生物标志物特征进行了研究，将红层原油划分为不同类型，在油源对比的基础上，对红层原油的物性、族组成和生物标志物特征进行了分析，并对红层原油的物性、族组成和生物标志物特征进行了研究。结果表明，不仅沙四上亚段、沙三下亚段，而且过去认识不深的沙四下亚段对红色岩的成油有重要贡献，东营凹陷古近系红色岩具有很大的勘探潜力，是今后增储上产的主要地区。
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.
