聚合物驱近年来在油田应用非常广泛,而且对提高原油采收率起着非常重要的作用.随着聚合物驱在油田广泛应用,聚合物在地下的滞留导致了聚合物驱替后测井曲线出了新的变化特征,对油水层的正确划分及相关计算有非常大的影响.在研究聚合物驱岩石电阻率变化规律之前,需要先弄清不同分子量聚合物,在不同浓度及不同配置水溶液矿化度下的聚合物溶液电阻率变化规律,为确定聚合物驱后地层混合液电阻率及其对储层电阻率的影响奠定基础.

In recent years, polymer flooding has been used widely and plays a very important role in enhancing oil recovery. Along with the application of polymer flooding, the retention of polymer makes new variation characteristics in logging and has a major influence on division and correlation calculation of water/oil bed. Before studying the change law of rock resistivity in the process of polymer flooding, we need to figure out the change law of polymer solution resistivity in the different situation of molecular weight, concentration and the salinity of different distributing water, which can lay a foundation for determining the mixed fluid resistivity and analyzing its influence on formation resistivity after the polymer flooding.
