摘　　要：用界面张力仪、表面黏弹性仪和Zeta电位仪研究了胜利埕东油田聚合物强化泡沫复合驱中聚合物和/或发泡剂质量浓度对油水界面特性及乳状液稳定性的影响。结果表明,随聚合物质量浓度增加,模拟水与原油模拟油间油水界面张力、界面剪切黏度和油滴表面的Zeta电位绝对值增大;而随发泡剂质量浓度增加,模拟水与原油模拟油间的界面张力降低,界面剪切黏度有所增加,但变化幅度很小,油滴表面的Zeta电位绝对值增大;原油模拟油与含聚合物和发泡剂的模拟水间所形成的W/O乳状液稳定性随聚合物和/或发泡剂质量浓度增加而增强。Effects of concentration of acrylamide polymer and/or foamer in composite oil displacing agent produced by Shengli Chengdong Oil Field on interfacial properties and emulsion stability of simulated crude oil/water system were investigated with interfacial tensiometer,interfacial viscoelastometer and Zeta potentiometer.Results indicated that as the concentration of the acrylamide polymer increases,the interfacial tension,the interfacial shear viscosity and the absolute value of the Zeta potential of the oil droplet surface increase accordingly.As the concentration of the foamer increases,the interfacial tension of the simulated crude oil/water system decreases accordingly while the interfacial shear viscosity increases with a little amplititude,and the absolute value of the Zeta potential of the oil droplet surface increases accordingly.The stability of water-in-oil emulsion of the simulated crude oil/water system enhances as the concentration of the acrylamide polymer and/or foamer increases.
