摘　　要：页(泥)岩的孔隙从纳米级到微米级均有分布,且以纳米级为主。表征页(泥)岩的孔隙结构,一般采用吸附法测试孔径在50nm以下的孔隙,用压汞法测量50nm以上大孔,然后把二者结合起来就能得到页(泥)岩从微孔到大孔的全孔隙结构特征。Shale or mudstone has pore size distribution from nanoscale to micron order with nanoscale as the majority. In general, adsorption assay method is used to measure the pore size less than 50 nm while mercury penetration, to measure that more than 50 nm. The whole pore structure features of shale or mudstone from micropore to macropore can be obtained by using mercury--penetration--and--adsorption assay method.
