摘　　要：在用幂律模式来描述聚合物水溶液基泡沫液相流变性的基础上,建立了聚合物水溶液基泡沫在多孔介质中一维非稳态流动的数学模型。给出了聚合物水溶液基泡沫在多孔介质中非稳态流动的数值计算方法;并以聚丙烯酰胺水溶液基泡沫为例,对其在Boise岩心中一维非稳态流动的压降、含液饱和度、流动泡沫平均密度分布以及压降与无因次注入时间的关系进行了数值计算与分析。Based on the rheological behavior of the liquid phase of the polymer aqueous solution-base foam which was described by the power-law model,the model of one-dimensional unsteady flow of the polymer aqueous solution-base foam through porous media was established,the method of the numerical calculated of one-dimensional unsteady flow of the polymer aqueous solution-base foam through porous media was given,and taking the polyacrylamide aqueous solution-base foam as an example,pressure drop,fluid saturationthe,the average bubble density distribution and the relationship between pressure drop and dimensionless injection time of one-dimensional unsteady folw in Boise core are calculated and analyzed.
