A kind of water saturation explanatory model of argillaceous sandstone is presented, including the formation water alteration during the lithification, and the argillaceous sandstone conductive volume as micro pore conductive volume occupied by the bound water and conductive volume in the effective pore.

认为泥质砂岩的导电体积由两部分组成，即完全被束缚水占据的微孔隙(孔喉半径小于 0 。1μm ，其中的流体不能渗流)导电体积和有效孔隙中被可动水、束缚水占据部分的导电体积，泥质砂岩的整个导电响应为二者之和，但二者导电体的导电特性不同，各有其不同的几何因子。

When these coefficients are quadratic functions of the porosity, specific constituent orthogonal weighting coefficients are derived from these orthogonal conditions along with a discussion about how to extend the applicable range of the constituent orthogonal weighting coefficients in the orthogonal coordinates. Based on the combination of the theory of critical porosity and the constituent model, it presents a specific example of the constituent model that includes two transforming points. The reasonability of above-mentioned theories is shown by comparison of theoretical calculations and measured data on effective elastic moduli of clean sandstone or sandstone analogs saturated with pure water.
