在利用水驱动采油法的后期实践中,油层里的含水率会渐渐地变大,但是仍会有很多可动的剩余油被滞留于地层中。如果要增加这一块油层的采收量,那么就亟需增加储层微观非均质性方面的相关知识。在这样的需求背景下,该研究取得了非常大的发展,引起了各方面专家迅速而全面的研究。本文的目的就在于针对这一方面简单地做个总结,从储集层砂体的外部几何形态和内部的结构以及孔、渗空间的变化特点出发,简单地描述了与精细地质研究相关的重要方面:一是细化开发单元,二是成因单元砂体的连通性和连续性的描写和叙述,三是对流动单元的研究,四是表外面储蓄层的研究,五是砂体内部的建筑结构单元的划分,六是地质建模等。本文最后提出了笔者认为以后精细地质研究可能的研究和发展方向,对我国开采事业的进步产生了非常好的影响。
In the later practice of using water-driven production methods, the water content in the reservoir will gradually increase, but there will still be a lot of residual oil remaining in the formation. If we want to increase the recovery of this reservoir, there is an urgent need to increase knowledge about the micro-heterogeneity of the reservoir. In such a background, the research has made great progress, which has caused the rapid and comprehensive research of all kinds of experts. The purpose of this paper is to briefly summarize this aspect. Based on the external geometry and internal structure of the reservoir sandbodies and the characteristics of the pore and infiltration space, a brief description of the importance associated with fine geologic studies The first is to refine the development unit, the second is to describe and describe the continuity and continuity of the unit sand body, the third is to study the flow unit, the fourth is to study the outer layer savings layer, the fifth is the sand body building The division of structural units, six geological modeling. At the end of this paper, I propose that I believe that the future of fine geology research possible direction of development and development of China’s mining has had a very good impact.
