| 摘 要： | 建立了一种较实用的聚合物驱模型,较全面地考虑了聚合物驱替过程中各种复杂的物理化学现象及毛细管力的作用。引入＂传播时间＂的概念,将求解饱和度和浓度的三维问题转化为一维问题。采用算子分裂算法将沿流线的饱和度方程和浓度方程分解为典型的双曲方程和椭圆方程,从而实现对聚合物驱流线数学模型的快速、准确求解。研究表明,毛细管力对水驱油藏饱和度影响不大（饱和度最大绝对误差为2×10-4）,可以忽略,但对聚合物驱油藏饱和度影响较大（饱和度最大绝对误差为0.075）,是聚合物驱应该考虑的重要因素。

| Abstract: | This paper presents a practical model for polymer flooding in which the complex chemical-physical phenomena and the capillary pressure effect are considered.And introducing transit time concept,the 3D saturation equation is decomposed into a set of 1D equations(hyperbolic equation and ellipse equation) by employing the operator splitting technique.With the 3D streamline simulator,the polymer flooding model can be calculated fast and accurately.The study shows that the little effect of capillary pressure on ... |
