低渗岩石孔渗及相对渗透率测试方法综述

摘要

Porosity, permeability and relative permeability are basic measurement parameters in core analysis experiment. However, the existing experiment methods are mostly for medium and high permeability cores, there is a lack of consistent and normalized measurement method and technique for low permeability cores. This paper has referred to a large volume of relevant literatures, reviewed the measurement methods and techniques of porosity, permeability and relative permeability of low permeability cores at home and abroad, summarized the problems appeared in testing process, and proposed preliminary solutions.%孔隙度、渗透率以及相对渗透率是开发实验中基本的测量参数,但现有的开发实验方法主要都是针对中高渗油藏的,对低渗油藏岩心样品缺乏统一、规范的测试方法和手段.在参考大量相关文献的基础上,分析了近年来国内外低渗岩石的孔隙度、渗透率及相对渗透率的测试方法和技术,总结了测试过程中存在的问题,并提出了初步的解决方案.
