油藏储层岩石孔隙结构三维重构方法综述

A Review of Three-dimensional Reconstruction of Pore Structure of Reservoir Rocks

通过建立函数来描述油藏储层岩石孔隙结构的统计性质和拓扑性质,并借助计算机再现岩石的三维孔隙结构,对研究地下原油流体的微观渗流特征具有十分重要的意义。依据国内外的有关文献,介绍了对岩石孔隙结构进行三维重构的主要方法和相关算法及其局限性,并就三维重构方法未来研究的重点和方向提出了建议。

The reservoir rock pore structure of 3 D reconstruction method refers to the building function to describe the statistical properties and topological properties of pore structure by using a variety of mathematical theory. Computer aided reconstruction of 3D rock pore structure reflects the true rock pore structure to a certain extent, and has very important significance to study the micro flow characteristics of underground fluid oil. This paper discusses the development process of 3 D reconstruction method of rock pore structure, and summarizes the recent progress of 3 D reconstruction method both at home and abroad. The current 3D reconstruction problems and technical challenges are also analyzed, so some countermeasures to improve the 3 D reconstruction method are put forward. And the future development direction of reconstruction method is prospected.
