摘要

通过对南华北地区谭庄凹陷断裂特征和构造样式的深入研究

确认谭庄凹陷发育了叶鲁断裂、商水断裂等29条断裂。叶鲁断裂和商水断裂分别是谭庄凹陷南、北边界的主控断裂

控制着凹陷内下白垩统和新生界的沉积与保存。谭庄凹陷发育4套烃源岩层系

下白垩统、石炭-二叠系是凹陷内的主力烃源岩层系

古近系、中-下侏罗统为潜在烃源岩层系。

Abstract

A thorough research of faulting features and structural types in the Tanzhuang Sag of the southern part of the North China Basin reveals that the Sag had developed more than 29 faults

of which the Yelv and the Shangshui are the southern and northern boundary faults of the Sag respectively and control the Sag and preservation of the Lower Cretaceous and Cenozoic there.The Sag contains four sets of source rocks with the Lower Cretaceous and Permo-carboniferous being the main source rocks and the Tertiary and Lower-Middle Jurassic being the potential source rocks.
