| 摘 要： | 利用毛管模型中双电层理论和阳离子交换量与Zeta电位的关系,确定了毛管内电位与离子浓度的径向分布。依据离子浓度分布与液体传质理论,推导了离子导电岩石的扩散吸附电动势方程。利用此方程进行了计算,结果表明:地层水矿化度、阳离子交换量、电解质类型对扩散吸附电动势影响较大;温度的高低、渗透率的大小对扩散吸附电动势也有影响;扩散吸附电动势与孔隙度的大小无关。

| Abstract: | According to the theory of electric double layer potential in a capillary and the relationship between Zeta potential and cation exchange capacity, the radial distribution of potential and the ion concentration were determined. On the basis of the distribution of ion concentration and the theory of matter transfer in liquid, the expression for diffusion and absorption electromotive force was deduced. The computation results with the expression show that the effects of water salinity, cation exchange capacity, temperature electrolyte type and permeability on the diffusion and absorption electromotive force are obvious, and that the diffusion and absorption electromotive force has no relationship with porosity. |
