本文建立了聚合物驱油过程中，地层流体的流变参数发生变化的幂律流体的油井流入动态方程，用有限差分法进行了求解，绘制了油井流入动态关系曲线和压力分布曲线，分析了流变参数对油井ＩＰＲ曲线形态的影响，并用１口井的实测资料进行了验证，吻合较好。
In this paper, dynamic equation of well flow of power-law fluid with changing rheological parameter of formation fluid during polymer flooding is established and solved by finite difference method. The dynamic relation curve and pressure distribution curve of oil well inflow are established. The influence of rheological parameters on the shape of oil well IPR curve is verified by the measured data of one well, which is in good agreement.
