摘要
本世纪40年代以来,广泛采用人工注水,即所谓二次采油法,近年来提出改型水驱油,即在水中加入某几种化学试剂,即所谓三次强化采油法,使注入水的性质改变,以进一步提高采油率。本文研究二维,多组分,多相,可压缩混合流体组成的注化学溶液强化采油数值模拟,计算方法和理论分析。在过程中包含注入表面活性剂,酒精,聚合物。
A two-dimensional, multicomponent, multiphase,composite reservoir simulator has been developed and applied to micellar/polymer flooding.The mathematical model of the two dimensional boosted oil recovery simulation can be described by a system of nonlinear partial differential equations.We put forward the continuous time finite element and discrete time finite element methods.Optimal order estimates are derived for the errors in the approximate solutions.
