摘　　要：以聚合物驱油机理为基础 ,分析了聚合物驱油过程中影响聚合物驱油效果的主要因素 ,确定了水驱及聚合物驱油过程中流度的变化 ,利用油藏介质基本特性的分布规律研究聚合物驱油改善油藏垂向驱替效果及程度 ,对驱替效果进行必要的评价和分析 ,为聚合物驱油合理粘度的选择和效果评价提供了理论基础和实际分析方法。Basing on the mechanism of the polymer flooding, this paper analyzes the factors influencing the effectiveness in polymer flooding, ascertains the changing between water and polymer flooding, making use of the basic distributing rule of the reservoir porous media to investigate the vertical improving effect and degree caused by the polymer flooding, puts up necessary evaluation and analysis to the displacing efficiency and thus provides a theoretical basis and practical analyzing method for the choice and effective evaluation of the reasonable viscosity in the polymer flooding.
