采用聚合物驱油技术已在不断发展,实验表明,原油与聚合物的混合液具有非牛顿特性,但目前未有相应的理论模型。文中将聚合物流体看作符合幂律模式的拟塑性流体,建立了聚合物驱油井产能预测的数学模型,研究了产出液中,聚合物浓度对油井产能、IPR曲线形状及采油指数的影响。 Polymer flooding technology has been developed, the experiment shows that the mixture of crude oil and polymer has non-Newtonian characteristics, but there is no corresponding theoretical model. In this paper, the polymer fluid is regarded as a plastic fluid which meets the power-law model. A mathematical model for predicting the productivity of polymer flooding wells is established. The effect of polymer concentration on oil well productivity, IPR curve shape and oil recovery index .
