一种快速求解交联聚合物驱数学模型的方法
A Fast Solution to the Mathematical Model of Cross-linked Polymer Flooding
摘要
Abstract
To solve the problem of the poor computational efficiency in solving reservoir mathematical model,we studied a fast solution. A three-dimension,two-phase(oleic,aqueous)and five-component(oil,water,polymer,cross-linked polymer, cross-linker)mathematical model was presented according to the profile control and flooding mechanism of cross-linked poly-mer flooding. Based on IMPES method,a more efficient and more stable Douglas difference scheme was proposed which uses the step-by-step reduced-order idea to solve a model. The simulation result shows that compared with commercial simulator CMG,the Douglas difference scheme in combination with chase method can greatly improve the solution efficiency,which provides an effective way to solve a reservoir mathematical model.关键词
