| 摘 要： | 以储层岩石的串联毛管模型为基础,建立描述含水储层岩石时间域激发极化效应的数学模型.数值模拟储层岩石孔隙中离子的浓差极化效应和双电层形变效应.孔隙中浓差极化控制着激发极化随时间的变化,双电层形变不控制激发极化随时间的变化.浓差极化效应对激发极化极化率的贡献较小,双电层形变效应对激发极化极化率的贡献较大.激发极化充放电过程的快慢,主要取决于固液界面阳离子的吸附能力和岩石的孔隙结构.

| Abstract: | Based on a microscope capillary model,a mathematical model for induced polarization of reservoir rock is obtained.Influences of concentration difference polarization and electric double-layer deformation on induced polarizability are studied numerically.It shows that induced polarization is governed by ion concentration difference polarization in capillary.Electric double-layer deformation has greater influence on total polarizability.Speed of charging and discharging in induced polarization depends mainly on cation exchange capacity and pore structure of rock. |
