摘要

复合驱油过程是一个多相色谱过程.运用多相多组分非线性色谱模型，模拟了表面活性剂-聚合物驱油过程，用特征线法求出相饱和度和组分浓度波的特征速度，然后，用特征向量积分给出它们在物理空间上的分布剖面.结果表明，聚合物浓度激波先于表面活性剂激波出现;相饱和度受溶质运动的影响可以产生多重激波，这使油相流动能迅速形成油墙.利用该模型讨论了溶质浓度、驱替速度、吸附和分配参数对采收率的影响.

Abstract

The combined flooding in oil recovery is a multiphase chromatographic process.Modeling for multiphase

multicomponent nonlinear chromatography was applied to simulation of the surfactant/polymer flooding process.By means of the method of characteristics

the characteristic velocities of saturation and concentration waves were solved.Then

integrating the eigenvectors led to wave profiles of saturation and concentration in physical spatial domain.The simulation results indicated that the concentration shock of polymer appeared earlier than that of surfactant; moreover due to solutes’movement

saturation wave could develop into multi-shock

which enabled the oleic flow to form oil bank rapidly.In addition

the influencing factors

such as concentration

flow velocity

adsorption constant and partitioning coefficient were also discussed.
