深部储层储集空间类型划分方案探讨——以胜利油区渤南洼陷沙四段为例

DISCUSSION ON CLASSIFICATION SCHEME OF THE PORE TYPES OF THE DEEP RESERVOIR Taking the upper part of the Member 4, Shahejie Formation, in Bonan Subsag, Shengli Petroleum Province for example

通过对胜利油区渤南洼陷深部储层特征的研究 ,提出了深部储层孔隙类型划分方案 ,将孔隙划分为原生孔隙、次生孔隙和混生孔隙三大类 ;将裂缝划分为构造缝、重力滑移缝、异常压力缝、成岩缝、原生缝、塑性变形面、溶蚀裂缝七大类 ,把裂缝型储层提到了与孔隙型储层同等重要的位置 。

Through studying the petrology characteristics, the author puts forward the classification scheme of the pore fissure types of the deep reservoir and emphasizes the fissure reservoir. The pore types of the deep reservoir are divided into three types, namely, the primary pore, secondary pore, and mixing pore. The fissure types of the deep reservoir are classified as seven types, namely, the structure fissure, gravity fissure, abnormal fissure, diagenetic fissure, primary fissure, plastic fissure as well as solution fissure.
