By the use of the component sandstone electric conductivity model, the effect of the pore structure characteristic parameter to cementation exponent m and saturation exponent n in the Archie formula were studied. It can be found the cementation exponent m mainly reflects the pore space size and its sizes distribution. The m is bigger, the pore space is bigger, the throat is simpler, and the reservoir is better.

通过致密砂岩电导模型分析研究致密砂岩孔隙结构特征参数对Archie公式中的胶结指数m和饱和度指数n的影响，发现岩石胶结指数m主要是岩石孔隙空间大小及其大小分布的表征，m值越大的岩石其孔隙储集空间越大，孔喉越简单，储集性能越好；反之，m值越小，岩石储集性能越差。
