特低渗透率的测定方法综述

Summarizing the measuring methods of ultra-low permeability

特低渗透率的测量一直是石油领域研究的热点问题,随着低渗透油田的开发、煤层气及页岩气的开采,其日益受到人们的重视。在参阅国内外相关文献的基础上,对目前测量特低渗透率的方法进行归纳,分别介绍了每种方法的工作原理,并简单总结了各自的优缺点。

The ultra-low permeability measurement is a hot issue in the oil areas.With the development of low-permeable oilfeild, coalbed methane and shale gas,the measurement of ultra-low permeability have being paid increasing attentions.Based on related literatures athome and abroad, this paper summarizes methods of measuring ultra-low permeability at present, and introduces the working principles of each method respectively.Moreover, this paper gives a brief summary of their advantages and disadvantages.
