摘　　要：针对影响聚合物驱提高采收率值的油藏韵律性、油藏润湿性、油层厚度、原油黏度、聚合物段塞质量浓度、非均质因数、聚合物用量、井距、纵向与横向渗透率比值和中心井比例 1 0项因素 ,应用了多元回归分析法以及拉格朗日插值数学理论 ,建立了预测聚合物驱提高采收率幅度的数学模型 .Reservoir rhythmicity, reservoir wettability, thickness of pay sand, oil viscosity, mass concentration of polymer slug, heterogeneity facto r, polymer volume, well spacing, ratio of longitudinal permeability to horizonta l permeability and weight of center producer are 10 major factors influencing th e value of the enhanced oil recovery of polymer flooding. According to the theor y of multivariable regression and theory of Lagrangian interpolation, a mathemat ical model for predicting the value of the enhanced oil recovery of polymer floo ding is established in this study.
