摘要/Abstract

摘要： 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的差分方法,这一模拟是一个完整的关于注入胶束/聚合物化学溶液的过程.在过程中包含注入表面活性剂、酒精、聚合物、盐水和碳氢化合物的各种化学溶液去驱替油藏岩石中的石油.其数学模型是一组非线性偶合偏微分方程组的初、边值问题.提出了一类差分格式,并得到最佳阶的误差估计结果.无疑将对这一领域的模型分析、数值方法、机理研究和软件研制均有重要的理论和实用价值.

Abstract: A two-dimensional, multiphase, compressible, compositional reservoir simulator has been developed, and applied to micellar/polymer flooding. The mathematical model for the two-dimensional enhanced oil recovery simulation can be described by a system of nonlinear partial differential equations. We put forward a class of finite difference scheme. The estimates obtained are the best possible.

Key words: enhanced oil recovery simulation, finite difference methods, chemical flooding
