人工岩样的砂粒配比研究及应用

摘要

Artificial rock is absolutely necessary for exploitation research in oil - field. For a long time,a large number of artificial stone were made out for choosing their physics property by investigator for their research. This paper build up the relationship between the porosity and permeability of the rock with diameters of sands by using ideal global grain model, which give the theoretic foundation to sands choice for making artificial stone.%人工岩样是油气田开采研究中必不可少的用品。长期以来，人们根据经验制作大量的岩样供研究者选出物性参数适应要求的样品进行实验研究。文中以理想球形模型建立了颗粒直径配比与人工岩样的渗透率和孔隙度的关系，为制作人工岩样进行砂粒选配提供了理论依据。
