| 摘 要： | 针对目前已有的聚合物驱分流量方程没有考虑聚合物溶液在储层中的流变性,无法准确描述聚合物驱油藏动态的问题,从多相渗流力学理论出发,综合考虑聚合物溶液物化特性、储层物性和相渗曲线特征等多种因素的影响,建立了早期聚合物驱分流量方程。实例分析表明,所建立的分流量模型能够较好地预测早期聚合物驱油田含水上升规律,可对聚合物驱效果进行快速评价。

| Abstract: | The existing fractional flow model of polymer flooding does not take into account the rheological property of polymer solution in reservoirs and can not accurately portray reservoir performance.Therefore,an early stage fractional flow model has been established for polymer flooding based on the principle of multiphase flow through porous media with consideration of physical and chemical properties of polymer solution,reservoir properties and the characteristics of relative permeability.Cases analysis shows ... |
