岩石的复电特性起因于它的电导和介电响应。电导与自由电荷的移动有关,介电响应与孔隙--颗粒介面上的极化现象相关联。可见这种介面极化可以在复电阻率和岩石孔隙度之间提供一种关联,而岩石孔隙度又可以通过一个Kozeny-Carman型关系与岩石渗透率联系起来,这就在复电阻率与渗透率之间建立了一种联系。本文计算了不同孔隙度的岩石模型的复电阻率和渗透率,从计算出的复电阻率和渗透率中进行分析,建立利用岩石的复电阻率来求取岩石渗透率的公式,验证了用岩石的复电阻率求取渗透率的可行性。
The complex nature of the rock is due to its conductance and dielectric response. Conductance is related to the movement of free charge and the dielectric response is related to the polarization on the pore-particle interface. It can be seen that this interface polarization can provide a correlation between complex resistivity and rock porosity, and that the rock porosity can be related to rock permeability by a Kozeny-Carman type relationship, Between the rate established a link. In this paper, the complex resistivity and permeability of rock models with different porosities are calculated. From the calculated complex resistivity and permeability, the formulas for calculating the rock permeability using the complex resistivity of rock are established. Permeability of rock complex resistivity.
