摘　　要： 对水溶性阳离子高分子(SCP)进行一系列物模驱油实验,结果表明SCP比非离子高分子(NIP)有更好的驱油效果,在低矿化度(3×103 mg/L)下采收率可提高43.8%,高矿化度(1×105 mg/L)下能提高18.1%的采收率。SCP在人造岩心多孔介质中的阻力系数约为部分水解聚丙烯酰胺聚合物3530S的2倍,在不同pH值和电解质浓度下,SCP对原油乳液Zeta电位的影响比NIP大的多。用透射电镜分析SCP分子的结构形貌,初步考察了SCP的抗盐性。 A series of oil displacement performance of water-soluble cationic polymer （SCP） were investigated. The results showed that SCP had better efficiency of oil displacement than NIP （nonionic-polymer）. The efficiency of oil recovery would increase 43.8% in low salinity（3×10^3mg/L） and 18.1% in high salinity （1×10^5mg/L）. The Fr. in laeunaris medium of SCP was about twice of polymer 3530S（a sort of Hydrolytic Polyacrylamide）. At different pH values and electrolytic concentrations, the effect of SCP on Zeta potential of crude oil was larger than NIP. Through TEM （Transmission Electron Microscopy）, the molecular state of SCP was observed and the effect of salt on SCP congeries was tentatively discussed.
