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.
