摘　　要：研究了驱油剂对模拟三元复合驱采出水油水分离性能、油滴Zeta电位、界面张力、流变性及油滴粒径的影响。HPAM提高体相粘度和油滴Zeta电位,促进油滴聚并,对界面张力和粘弹性模量影响不大,随着其浓度的提高,模拟采出水的稳定性先减小后增强;表面活性剂提高Zeta电位,减小界面张力和粘弹性模量,并阻碍油滴聚并,随着其含量的增加,稳定性显著增强;碱提高Zeta电位,减小界面张力和粘弹性模量,随着其含量的增加,稳定性先增强后减弱。Studied in this paper are some effects of oil displacement agent on oil-water separation,Zeta potential,interfacial tension and rheology and droplet size.The liquid viscosity and Zeta potential are enhanced by HPAM;slight are the effects of HPAM on interfacial tension and viscoelastic modulus.And HPAM promotes the coalescence of oil droplets,so the stability of simulated produced water is decreased first and then increased with the increase of HPAM concentration;Zeta potential is increased;interfacial tension and viscoelastic modulus are decreased;the coalescence of oil droplets is prevented by surfactant;stability is increased significantly with the surfactant content increasing;Zeta potential is increased and interfacial tension and viscoelastic modulus are decreased by alkali;stability is initially increased and then decreased with the increase of NaOH content.
