摘要
聚合物溶液的有效粘度由剪切粘度和弹性粘度组成。引用德博拉数的概念表述聚合物溶液的弹性粘度 ,并将有效粘度代入压力方程中 ,用有限差分方法求解 ,得到地层中的压力及井底压力变化曲线 ,并分析了曲线的对比结果。
The effective viscosity of polymer solution consists of shear viscosity and elastic viscosity. This paper uses the concept of Deborah number to illustrate the elastic viscosity of polymer solution. It substitutes the pressure equation with effective viscosity, finds the solution with finite difference method to obtain the formation pressure and downhole pressure change curves and analyzes the comparative result of the curves.
