摘　　要：通过研究地层导电机理和水淹过程中混合液电阻率的变化规律,提出了一种基于纯砂岩导电模型计算混合液电阻率的方法。首先将砂岩储层等效为体积模型,根据并联导电模型得到混合液电阻率与原生水电阻率、注入水电阻率的数学关系,然后结合纯砂岩的Archie公式进行迭代求解,得到混合液电阻率和含水饱和度。该方法在L油田的实际应用中取得了很好的应用效果,证明该方法是可行的。By studying the formation conductive mechanism and the changing rule of resistivity of mixed formation water in the process of mixture, this paper proposes a method for determining resistivi- ty of mixed formation water based on a pure sandstone conductive model. Firstly, the sandstone reser- voir is simplified as a volume model and there is a relationship between the resistivity of mixed forma- tion water and connate water resistivity, the injected water resistivity based on the parallel conductive model. And then the resistivity of mixed formation water and water saturation will be determined after iterating with Archie formula. The practical application of this method in L oil field is very effective and useful.
