本文简述一种测定岩心孔喉半径分布的新方法。它是将岩心用润湿性液体(水或煤油等)饱和,然后使空气渗流过岩心,以泊稷叶定律和毛细管理论为依据处理实验数椐,得到孔喉半径分布曲线。将其与渗透率联系起来便得出孔喉半径分布峰位与岩样空气和水渗透率的关系曲线。经大量实验证明该法实验数据平行可靠,对研究油层损害等问题有很大实用价值。 This article describes a new method for determining the distribution of core throat radius. It is the core wetting liquid (water or kerosene, etc.), and then the air seepage through the core, based on the law of Boyer’s leaf and capillary theory to deal with experimental number 椐, pore throat radius distribution curve. Associated with the permeability, the relationship between the peak position of the pore throat radius and the permeability of air and water in the rock sample is obtained. After a large number of experiments show that the method of experimental data parallel and reliable, the study of reservoir damage and other issues of great practical value.
