低渗透储层润湿性测量方法研究进展

Research progress in wettability measurement of low permeability reservoir

当前低渗透油气资源发挥着越来越重要的作用,尤其是非常规页岩油气,其以巨大的资源量成为了当今油气藏领域研究的热点内容。低渗透储层润湿性是油气藏开发过程中最重要也是最难获得的储层物性参数之一,因此能否准确判断润湿性是制约低渗透储层有效开发的瓶颈之一。文章对国内外常规低渗透储层和非常规页岩储层润湿性的测量方法进行了广泛深入地调研,详细阐述了各种方法的实验原理、实验步骤、润湿性判断标准及优缺点,为国内该领域的研究提供了一定的理论基础。

Nowadays low permeability oil and gas resources are playing an important role.Shale oil and gas has become a hot spot in current research due to its huge resources. Wettability of low permeability reservoir is one of the most important parameters during oil/gas development which is difficult to obtain. Therefore, whether or not to measure precisely the wettability of low permeability reservoir is one of the bottlenecks to develop this reservoir effectively. Thus this paper extensively reviewed the domestic and international references related to the methods measuring conventional low permeability reservoir and unconventional shale reservoir wettability. The experimental principles, experimental procedures, the judg-ment standard of wettability, the advantages and disadvantages of each method were detailed presented. All those studies above can provide a theoretical basement for domestic investigation.
