储层微型构造与剩余油分布关系研究

油田进入特高含水期后，搞清楚剩余油的分布是关系油田生存的一项重要课题。通过在胜三区进行微构造分析，研究实际测井数据，认为储层的含油饱和度和综合含水率受微型构造的控制，对处于同一开发期的井来说，同一韵律层中位于鼻状构造高部位的井的综合含水率要低于位于侧翼部位的井的综合含水率，而含油饱和度数值却较高。研究证实．微型构造是控制剩余油分布的主要因素之一。

A Study of the Relationship between the Micro-tectonics and the Distribution of the Remaining Oil

When it is in the post productive period,the distribution of the remaining oil is of vital importance to the oilfield.A study of the third region of the Shengtuo Oilfield shows that many types of inherited micro tectonics are developed along the faults in the northeast of the region.Utilizing the logging data analysis,the author argues that the saturation and the ratio of the water in wells are well controlled by the micro tectonics.Within the same small nose like structure,under the same period of the development of the oilfield,the ratio of the water in the high places of wells is less than that in the side places of wells,but the saturation is reversed.Finally,this paper shows that micro tectonics is one of the key factors that determine the distribution of the remaining oil.
