摘　　要：研究聚合物浓度、含盐量及岩心的渗透率对两性离子聚丙烯酰胺在岩心中滞留量的影响,结果表明:两性聚合物浓度增加,滞留量增加;在本实验研究的含盐量区间内,滞留量随含盐量的增加而下降;随岩心渗透率的增加,滞留量降低。The retention effects of amphoteric polymer concentration, salinity and the permeability of the core are researched. The results show that retention increased with the increasing concentration of amphoterie polymer. the salinity range of experiment, retention decreases along with the increasing salinity. With the increasing of the core permeability, retention is reduced.

关 键 词：滞留 渗透率 两性聚合物 含盐量 岩心
