Testing on rock sample data in dispersed shaly sands it shows that adding another parameter ( n ) to the model can decrease the relative error of fitted co. however, when we consider the difference of electrical properties between clay - bound water and formation water in the model, although another parameter ( qv ) is added to the model, the relative error of fitted co is increased slightly

模型中增加參數n （ m n ）可以使擬合的c _ t的相對誤差減小，但在考慮粘土結合水與地層水導電性差別時，
模型中雖多加一個參數q _ v ，卻沒有減小擬合的c _ t的相對誤差。
Based on the effective medium hb resistivity models in laminated or dispersed shaly sands proposed by berg, the general effective medium hb resistivity model in laminated and dispersed shaly sands is established. in the derivation of the model we assume that clay - bound water fraction is included in total pores, clay - bound water and formation water have the same resistivity, and yet the difference of electrical properties between the two waters is incorporated into clay grain conductivity
