摘　　要：采用核孔膜过滤实验,研究了微米级交联聚合物微球的封堵性能。结果表明,矿化度对SMG-μm微球的封堵效果有很大影响,随着NaCl的质量浓度增大,封堵效果越好;在压力和微球质量浓度相同时,不同核孔膜孔径的过滤时间有很大差异;SMG-μm微球在较低压力下的封堵效果优于高压力的封堵效果;实验发现,质量浓度对过滤时间的影响比较复杂,没有明显的规律可循。The plugging effect of micro crosslinked polymer microspheres was studied by using nucleopore membrane filtration experiment.The experimental results show that the salinity has a great effect on the plugging effect of SMG-m microspheres.With the increasing of NaCl concentration,the plugging effect becomes better.Under the conditions of same pressure and microsphere concentration,the filtration time of SMG-m microspheres is better than that of high pressure.The results show that the effect of concentration on the filtration time is complicated and there is no obvious regularity.
