摘要： 根据有限元单元计算叠加原理,提出了计算有限体积过程中控制体积内流量的方法,这种方法可以在一个有限元平台上开发结合有限元和有限体积的油藏数值模拟器。该方法只借鉴有限体积方法控制体积内流体流量计算的思想,而不用划分有限体积网格;每条控制体积边界流量较传统有限体积方法少算一次,从而大大减少了计算量和编程的难度,提高了油藏数值模拟的效率。

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
