| 摘 要： | 结合东濮凹陷地质特点，探讨研究了东濮凹陷泥岩裂缝油气藏形成的地质条件，东濮凹陷油气源岩发育，泥岩裂缝发育，泥岩裂缝油气成藏有着较好的成藏条件，是一种新的油气藏类型，有着良好的勘探前景，同时对泥岩裂缝油气藏在东濮凹陷的分布特点进行了研究。指出高压区及超高压区，盐岩分布区，构造转换带是寻找这类油气藏的有利地区。层系上，沙三^2-4是勘探这类油气藏的有利层系，一些稳定的泥，页岩标志层也是寻找这类油气藏的有利层段。

| Abstract: | Combing with the geological characteristics of Dongpu depression,this paper discusses the geological conditions concerning the formation of the oil pools formed in the fractures of the shales.The oil source is well developed in Dongpu depression,and so are fractures in shales,which have better conditions to form the oil pools in the fractures in shales,the new type of reservoir that has the prospect for the future exploration.This paper also studies the distribution of this sort of oil pool in this depression,and points out that the area with high abnormal pressure;salt distribution area and the structure transforming zones ard favorable.Vertically,this sort of oil pools can be easily found in the members from Es2 to Es4,because there are some stable shale or clay marker beds in them. |
