摘　　要：本文介绍了聚合物驱油的两维两相三组份的非线性数学模型,给出了一种较有效的有限元数值解法,并用FORTRAN语言进行了程序设计,利用五点法井网的一组数据进行了模拟计算。模型试算表明,与注水驱油相比,不同的注聚合物溶液段塞驱油,可以不同程度地提高驱油效率,同时说明给出的有限元方法可以进行聚合物驱油的数值模拟。In this paper, an efficient finite element method is presented for a two dimensional, two phase nonliear model of polymer flooding The associated co- mputer program is designed and a simulation using some data of a 'five point well pattern was carried out. It is shown that polymer flooding can increase the production efficiently and greatly as compared to water flooding. But pr- oper polymer slug size should be selected in view of economy. It is demonstrated that finite elment method can be used in the simulation of polymer flooding.
