摘　　要：用阳离子双子表面活性剂GS16-3-16与十二烷基硫酸钠SDS制备了带负电荷的囊泡,将其与疏水缔合聚合物AP-P4复配,通过实验研究了囊泡与聚合物溶液间的协同效应。结果表明,复配体系的界面张力、表面张力随囊泡浓度的增加呈先降后升再趋于稳定的趋势,体系的粘度则呈先升后降再趋于稳定的趋势;上述性质的变化与囊泡浓度密切相关:当浓度在6mmol/L左右时,体系的界面张力最低;当浓度为0.8mmol/L时,体系的粘度最高。研究结果对改善疏水缔合聚合物在三次采油中的驱油效果有一定的意义。The vesicle with negative charge was prepared by gemini surfactant GS16-3 16 and sodium dodecyl sulfate （SDS）, which mixed with the hydrophobic associative polymer AP-P4. The synergistic effect of the vesicle/polymer mixture was studied in this paper. The results indicated that the surface/interfacial tension and viscosity of this mixture are close related to the concentration of vesicle. The trends of the surface/interfacial tension changed from descending to rising, and then tend to stable with increasing of the vesicle concentration. While the trends of the viscosity changed from rising to descending, and then tend to stable. The interfacial tension of the mixture was almost zero when the vesicle concentration was 6mmol/L, while the viscosity reached the highest value when the vesicle concentration was 0.8mmol/L. The result of this paper has significance on enhancing oil displacement efficiency of polymer flooding.
