Abstract

Abstract: In this paper a practical numerical computation method,namely improved finite element method to solve fluid flow in de-forming reservoir is presented, which is used to solve the ther-mal equation and rock deforming equation by combining with fi-nite difference method. Since the finite element method has its own advantages in designing grid system and treating complicat-ed reservoir boundary and it has been successfully applied to flu-id field study, it is used to solve the complicated mathematical model of hot fluid flow and deforming reservoir. The results from case study indicate that the new method is better than any other finite element or finite difference methods.

Key words: hot fluid-solid interaction, oil reservoir, finite element method, finite difference method, reservoir numerical simulation
