摘　　要：利用人造岩心,分析了碱水驱油过程中不同质量浓度、不同孔隙体积倍数的流度控制剂(聚丙烯酰胺溶液)对碱水驱油采收率的影响.结果表明,有流度控制的热碱水驱采收率比无流度控制的热碱水驱采收率高;相同聚合物溶液质量浓度情况下,碱水驱后的采收率随注入聚合物溶液孔隙体积倍数的增大而增大,而相同聚合物溶液孔隙体积倍数情况下,碱水驱后的采收率随注入聚合物溶液质量浓度的增大而增大.该实验条件下,最佳的流度控制剂孔隙体积倍数为1.22,质量浓度为1.5g/L.The effect of mobility control agent (PAM solution) of different mass concentration and different pore volume on oil recovery efficiency in alkaline water-flooding is studied by using the artificial core. The results of research show that the oil recovery efficiency of alkaline water-flooding with slug control is higher than that of non-mobility control in alkaline water-flooding, the oil recovery efficiency after alkaline water-flooding increases with the increase of polymer slug's pore volume in the same polymer mass concentration, the oil recovery efficiency after alkaline water-flooding increases with increase of the polymer mass concentration in the same polymer slug's pore volume. The best pore volume of mobility control slug is 1.22 and the best polymer mass concentration is 1.5 g/L.
