The pressure equations and the components' concentration equations were solved via upstream sorting implicit method, and then the chemical reaction equations were solved with Newton-Raphson iteration method. The implicit scheme introduced was compared with the traditional IMPEC method through ASP combination flooding simulation. The results showed that the stability was better, and the computational speed could be improved by more than 45% %K 隐格式 %K 数值模拟 %K 三元复合驱 %K IMPIMC %K < %K br> %K ASP combination flooding %K implicit algorithm %K IMPIMC %K numerical simulation %U http://gxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1672-3961.9.2014.003
