| 摘 要： | 滑脱断层作为一种独特的地质现象，在国内外含油气盆地中都有发现，本文运用钻井，区域地质等资料，对东濮凹陷马寨滑脱断层的形成机制及其地质意义进行了研究，结果认为：形成滑脱断层需具备斜坡，塑性岩体和区域构造应力场3个基本条件，滑脱断层面之下油气富集程度较高，之上较差，马寨滑脱断层的发现，。不仅丰富和发展了地质构造理论，而且加深了对东濮凹陷石油地质规律的认识。

| Abstract: | As a special geological phenomenon, detachment fault had been found in many petroliferous basins at home and abroad. By using drilling and regional geological data, this paper studies the genetic mechanism and geological significance of Mazhai detachment fault in Dongpu depression. The result is that, 3 basic conditions of slope, plastic rock and regional tectonic stress field were necessary for forming of detachment fault; oil accumulation was more abundant below the fault surface, and less abundant above. The discovery of Mazhai detachment fault not only enriched geological tectonic theory, but also gave a deeper understanding of petroleum geological rule in Dongpu depression. |
