摘要
非常规油气资源发挥着越来越重要的作用,页岩气以其巨大的资源量,成为当今非常规油气藏领域研究的热点。页岩储层渗透率是气藏开发过程中最重要也最难获得的储层物性参数之一,能否准确获得其渗透率值是制约页岩气藏有效开发的瓶颈之一。为此,文中对国内外页岩储层渗透率测量方法进行了广泛调研,详细阐述了各种方法的实验原理、实验步骤和数学求解过程,对比分析了各种方法的优缺点和影响因素,同时提出了当前页岩储层渗透率测量过程中存在的问题和研究方向,为国内该领域的研究提供了理论基础。
Nowadays, unconventional oil and gas resources are playing an important role. Shale gas has hecome a hot spot in current research due to its huge resources. Permeability of shale gas reserwir is one of the most important parameters during gas development which is difficuh to obtain. Therefire, whether or not to measure precisely the permeability of shale gas reservoir is one of the bottlenecks to develop shale gas reservoir effectively. Thus, this paper extensively reviewed the domestic and international references related to the methods measuring shale permeability. The experimental principles, the experimental procedures, the mathematical treatments, the advantages and disadvantages and the influencing factors of each method were elaborated, and then the problems and limitations appeared during the measurements were summarized and the direction of research was also pointed out. All those studies above can provide a theoretical basis tot domestic investigation.
