摘要

根据聚合物溶液具有黏性和弹性的特性，建立了瞬态流动数学模型，并采用有限差分法进行了求解。已绘制出类型曲线。分析了聚合物溶液的一些性质对型曲线特性的影响。与单纯考虑聚合物溶液为幂律流体的压力导数曲线相比，径向流态下考虑弹性向上的压力导数曲线更少。因此，在聚合物溶液压力的动态分析中，有必要考虑弹性因素。

Dynamic Analysis on Pressure of Viscoelastic Polymer Solution

According to the behavior that the polymer solution has the characteristics of viscosity and elasticity, the transient flow mathematical model has been established and has been solved by using finite-difference method. The type curves have been plotted. The influence of some properties of polymer solution on the characteristics of the type curve has been analyzed. Compared with the curves simply considering polymer solution as power-law fluid, it is shown that the pressure derivative curve considering the elasticity upwards less at the radial flow regime. Therefore, it's necessary to consider the elasticity in dynamic analysis on pressure of polymer solution.
