中文摘要：

综合利用地震、录井、测井等资料,通过断裂体系的静态描述和动态解析,结合现今残留地层特征、地层剥蚀特征及原始厚度恢复,对东营凹陷孔店期-沙四早期原始构造格局进行研究。结果表明：孔店期-沙四早期是东营凹陷构造应力场的转变时期,新产生的北东东向断裂和继承性活动的北西向先存断裂构成了该时期的控盆断裂体系,控制了该层系的原始沉积,形成了北断南超的断陷盆地,呈现＂盆岭相间＂格局;东营凹陷在孔店期-沙四早期全区均接受了原始沉积,形成陈南断层下降盘地区、博兴洼陷和林樊家地区3个次洼,林樊家凸起和青城凸起尚未形成;沉积期以及沉积后断裂体系的持续活动造成了原始地层被切割、改造,在凸起区、断层上升盘及南部缓坡区形成了缓坡带、堑垒带和断块的剥蚀,剥蚀厚度等值线呈近东西向展布。

英文摘要：

Based on the seismic data,log data,logging data and combined with remnant strata characteristic,denudation thickness and origin strata thickness research,the early Paleogene（Ek-Es4x） structure framework of Dongying sag was researched through geometrical and kinematic analysis of the fault systems.The results show that the period of early Paleogene（Ek-Es4x） is the stress field transformation phase and the NE faults begin to develop while the former Mesozoic faults（NW） last active,which are made up of the basin-control fault system,dominating the original strata sediment.The early Paleogene（Ek-Es4x） prototype basin in Dongying sag presents as a faulted basin with the north faulted boundary and the south overlapped to the Luxi uplift.The whole basin inherits the original deposition,and is divided into three parts（Chennan zone,Boxing zone and Linfanjia zone）.Moreover,the Linfanjia uplift and Qingcheng uplift don t form,which differs from the present basin.The activity rate change of the deposit and post-deposit fault systems brings the later reconstruction,leading to faulted gentle-slope denudation,graben-horst denudation and block denudation in the uplift,upthrow and south gentle slope.The denudation thickness contours distribute nearly in EW strike.
