摘　　要：东营凹陷前古近系地层结构复杂,地层展布南北、东西方向差异较大,地层划分与对比难度较大。在宏观分析华北板块构造演化特征基础上,通过野外露头、录井岩性组合、测井电性和地震反射等特征分析,建立了各层组地层划分与对比标志,明确了东营凹陷地层区域展布差异性,解剖了典型地区地层发育特征,研究了上古生界两种构造反转样式,以及构造反转运动对油气成藏的控制作用,为后续勘探工作奠定了基础。The pre-Paleogene stratigraphic structure of Dongying Sag is complex,with stratigraphic distribution which is quite different in the north-south and east-west directions,making stratigraphic division and correlation difficult. The stratigraphic division and comparison marks of each layer group were established based on the macroscopic analysis of plate tectonic evolution characteristics in North China,through the analysis of field outcrops,logging lithological combinations,logging electrical properties,and seismic reflections. And then the regional distribution differences of the strata in the Dongying Sag were clarified,and the stratigraphic development characteristics of typical regions were dissected. Two forms of tectonic inversions were studied in the upper Paleozoic,as well as the influence of tectonic inversion movements on hydrocarbon accumulation,providing the ground work for future exploration.
