摘　　要：为合理设计聚合物驱采油装置及生产制度,由连续性方程、运动方程、状态方程,考虑流体流变性的变化,建立了聚合物驱不稳定渗流的IPR曲线模型,结合油相IPR曲线进行加权,可以得到聚合物驱油藏不同含水条件下油井的综合IPR曲线。分析了含水率、注入液和采出液浓度对聚合物驱油藏油井综合IPR曲线的影响。Based on the continuity equation,motion equation and state equation, this paper studies the changes of fluid rheological properties and inflow performance relation(IPR)of unstable flow of polymer flooding.Combining with IPR of oil phase and weighting,it establishes synthetical IPR curve of polymer flooding.Some factors affecting IPR such as water cut,concentration of injection fluid and production fluid are analyzed.
