Development of Reservoir Numerical Simulator with Finite Element Method

Abstract

Abstract: Based on superposition principle of finite element (FE) calculation, a new method for flow rate control within finite volume (FV) is proposed, by which the reservoir numerical simulator combined with FE and FV on a finite element platform can be developed. By this method, the flow rate within controlled volume is calculated only by means of FV method rather than grid classification of FV and its calculated amount for boundary flow rate within control volume is less than that by one time by traditional FV method, thus greatly decreasing the calculating amount and programming difficulty, increasing the efficiency of reservoir numerical simulation.

Key words: reservoir numerical simulation, finite element, finite volume, superposition principle
