致密储层孔隙结构研究方法概述

Research method of pore structure in tight reservoir

对于致密储层,孔隙结构很大程度上决定了储层的性质,影响了流体流动机理,对储层的产能有很大影响,因此,储层孔隙结构表征一直是石油领域研究的热点问题。随着致密储层的油藏开发、煤层气及页岩气的开采,孔隙结构研究方法日益受到人们的重视。在参阅国内外相关文献的基础上,对目前致密储层孔隙结构表征方法进行归纳,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。

For tight reservoir, pore structure largely determines the nature of the reservoir and affects fluid flow mechanism, having a great impact on the deliverability of reservoir. Therefore, structure characterization of reservoir pore becomes the hot issues of the petroleum field. As the tight reservoir development, coalbed methane and shale gas exploitation, more and more people pay at- tention to pore structure research method. Based on the relevant literature, we concluded structure characterization of reservoir pore in tight reservoir. This paper respectively introduces working principle of each method, and briefly summarizes its advantages and disadvantages.
