摘　　要：用界面张力仪、表面粘弹性仪和Zeta电位仪测定了胜利孤东原油模拟油与含预交联聚合物凝胶颗粒溶液间的界面特性,并研究了预交联聚合物凝胶颗粒浓度对这些界面特性及乳状液稳定性的影响。结果表明,去离子水中加入预交联聚合物凝胶颗粒后,去离子水及模拟水与原油模拟油间的界面张力和界面剪切粘度及油滴表面的Zeta电位绝对值均增大,原油与预交联聚合物凝胶颗粒溶液间所形成的W/O型和O/W型乳状液稳定性均随聚合物凝胶颗粒浓度增加而增强。Interfacial properties between Shengli Gudong model oil and preformed particle gel solution were investigated with interfacial tensiometer,interfacial viscoelastometer and Zeta potential instrument.Meanwhile,the effects of the concentration of preformed particle gel solution on interfacial properties and emulsion stability were researched.The results indicate that the interfacial tension,the interfacial shear viscosity and the absolute value of Zeta potential between deionized water/formation water and model oil increase with addition of preformed particle gel.The stability of water-in-oil and oil-in-water emulsion formed by crude oil and preformed particle gel solution enhances as the concentration of the preformed particle gel solution increases.
