摘要
Abstract
In this paper, the limestone was acted as a porous material, different sub section limestone porosity value is calculated using the sonic logging curve, the nanoscale aperture distribution is studied using the nitrogen adsorption method combined with X-ray diffraction. Test results show that the different sub section limestone total porosity is 5-12%, the materials showed adsorption behavior based on mesoporous materials, The most probable aperture radius are between the 25-33nm; the specific surface area of each sample was positively related with the nitrogen adsorption amount.关键词
