摘要：
The multiscale finite element method was used to simulate general nonlinear elliptic equations and time-dependent nonlinear equations. The basic principle of the multiscale finite element method for solving nonlinear equations was described, and the corresponding calculation method was derived. The accuracy and the applicability of the proposed method were verified by two different kinds of nonlinear seepage flow. Finally, based on the study of the two models, the multiscale finite element numerical simulation of the water injection of the low permeability reservoir was carried out. The results indicate that MsFEM has higher accuracy compared to finite element method, and can reduce the computation time. © 2015, Central South University of Technology. All right reserved.
