摘要: 本文提出断面构造体系的新概念,并以东营凹陷王家岗油田为例,在阐明断面构造体系特征的基础上,研究了其油气遮挡能力,对不同断面的不同部位的封闭性作出了评价。同时探讨了断面构造体系对油气富集的作用,提出了"面背斜"和"面鼻"断面圈闭为油气勘探新领域。Abstract: The paper proposed a new concept of fault-plane structural system,taking Wangjiagang oilfield for an example.Based on a detailed description of the characteristics of fault-plane structural systems,their shielding capability for oil and gas is studied,and then the sealing properties on different parts of different fault planes are appreciated.The paper also approached to the role of a fault-plane structural system on oil and gas enrichment,and suggested that "planar anticline" and "planar nose" fault-plane traps are new areas of oil/gas exploration.
