摘要
在油藏数值模拟中对数值模型进行求解,目前基本有两类方法:一类是顺序求解法,如IM PES方法和IM P IM S方法;一类是联立求解法,如半隐式法和全隐式法。IM P IM S方法是一种顺序求解方法,是IM PES和半隐式方法的混合变种。它既具有半隐式求解饱和度的特点,又保留了IM PES方法省内存,省计算工作量的优势。
At present there are two methods to carry on the solution in the oil reservoir numerical simulation to the numerical model. One kind is the order asks the solution, such as IMPES method and IMPIMS method; another is the association stands asks the solution, such as implicit and semi-impliclt. IMPIMS is a sequential solution method, which is the mixture of IMPES and semi-implicit. It is of the characteristic of getting saturation by semi-implicit , and has the advantages of IMPES which saves mcmory and calculating work.
