| 摘 要： | 北京断陷形成于新生代,受北东向及北西向断裂活动的影响。本文根据地貌、钻孔、物探、探槽等方面资料的分析,研究了北京断陷新生代沉积地层和构造演化的关系。沉积中心的迁移与断裂的活动互相对应,有着良好的构造指示作用。石油储集层的储集体积、孔隙率和渗透率,决定其对石油的储集性能。本文用理论研究和测量,证明了构造应力场是影响石油储集层孔隙率和渗透率的主要因素。

| Abstract: | The Beijing Down-Warped Basin was controlled by Northeast-and Northwest-trending faults and received Cenozoic sediments.This paper studies the relationship between the migration of the deposition centers and the activities of the faults based on the analyses of geophysical,trenching,geomorphological and core lithological data.The migration of deposition centers corresponds well with fault activities and is a good indicator of tectonics. |
