摘要
三塘湖盆地二叠系储层主要为复杂岩性的裂缝-孔隙型储层。而裂缝-孔隙型储层的评价是一个世界级的难题。用岩心统计与测井响应特征的对应关系,建立一种有效识别岩性及裂缝,发现有利储层的方法。从马中油田3口井的分析得出:在同一构造应力条件下,岩性控制裂缝的发育,裂缝控制油气的分布。
The Permian reservoir in Santanghu basin is primarily complex lithologic fractured-porous reservoir. Unfortunately, the evaluation of fractured-porous reservoir is a problem all over the world. A method which identifies lithology, fracture and favorable reservoir by use of the correspondences between core data statistics and features of log response is provided in this paper. Through the analysis of three wells in Mazhong oilfield, it is concluded that lithology dominates the development of fracture, and fracture dominates the distribution of oil and gas under the same tectonic stress.
