摘要
建立网络模型,模拟计算电阻率和含水饱和度,探讨几种孔隙微观结构属性与其关系,分析润湿性对岩石电阻率的影响。研究结果表明,岩石孔隙结构对于水湿岩石的岩石电性特征有决定性的影响。
The effects of connectivity,pore size distribution and hydraulic radius of reservoirs rock on the curve of the resistivity index I with the water saturation Sw are simulated and analyzed by network model.Simultaneously,the effects of wettability on rock electrical property are simulated and analyzed.The results show that for water-wet rock,pore microstructure have important effect on rock electrical response.
