摘要： 通过对东濮凹陷内部主要断裂的特征进行分析,总结了东濮凹陷不同区域的构造特征。利用平衡剖面的基本原理对东濮凹陷构造演化过程进行研究,将东濮凹陷的构造演化过程划分为古近纪裂陷阶段和新近纪以来拗陷阶段。依据古近纪不同时期断裂活动的特征,将古近纪进一步分为4个演化期次:初始裂陷期(沙四段沉积时期);主要裂陷期(沙三段沉积时期);继承发展期(沙二段-沙一段沉积时期);裂陷消退期(东营组沉积时期)。沙三段沉积时期是东濮凹陷最重要的构造定型时期,整个凹陷的“南北分区,东西分带”的构造格局于此时期基本定型。

Abstract: The structural characteristics in different areas in Dongpu sag are presented. The evolutional process of Dongpu sag is studied with balanced cross section method and divided into rift stage of Paleogene and depression stage since Neogene. Based on the characteristics of fault activity of Paleogene, it is divided into four evaluating phases such as the original rift phase (corresponding to Member-4 of Shahejie formation), the major rift phase (Member-3 of it), the inheriting and developing phase (Member-2 to Member-1) and the rift subducting phase (Dongying formation), of which the Member-3 of Shahejie formation is the period of the most important structural shaping for Dongpu sag, forming the structural framework of blocks in south-north direction and zones in east-west direction.

Key words: Dongpu sag, Cenozoic, tectonic evolution, structural characteristic
