摘要
针对Algeria某油田油气层具有地层水矿化度高[（1．5～5）×10^5mg／L]电阻率低等特点，对储层非均质性，粘土矿物的附加导电作用及高矿化度地层水对油气层电阻率的影响进行了初步机理分析。根据实验数据得到不同岩性和不同地层水矿化度的m、n和b值的变化规律。实践证明用可变m、n和b值法计算储层的含水饱和度值比用固定的m、n和b值有明显改善。
For the oil/gas reservoir with high formation water salinity [（1.5～5）×10^5 mg/L-] ＆ low resistivity of × oilfield in Algeria, preliminary mechanism analysis about the influence of formation heterogeneity, additive conductivity of clay minerals and high salinity formation water on the resistivity of oil/gas reservoir was carried out. The variation principles of m, n and b values for different 5- thologies and formation water salinities are obtained. The practice proved that it is better to use variable m, n and b values to calculate water saturation than the fixed values.
