摘要： 利用稳定性分析仪和光学显微镜研究了B型和海博Ⅲ型2种驱油用两亲聚合物复配对其乳状液稳定性和乳化效果的影响;采用流变仪、界面张力仪和电位分析仪研究了该2种驱油用两亲聚合物及其复配体系的流变性能和界面特性。结果表明:2种驱油用两亲聚合物及其复配体系均能形成O/W型乳状液,随着B型两亲聚合物复配量的增加,复配体系乳状液粒径介于2种两亲聚合物单独形成的乳状液粒径之间,且逐渐减小,分布变窄;其外相体系的黏度、油/水界面张力和Zeta电位的绝对值均呈现先降低后升高的趋势;综合作用下,复配体系乳状液液滴的迁移速率降低,絮凝、聚并程度先升高后降低;相比于2种驱油用两亲聚合物单独使用时,复配体系乳状液的稳定性呈现先降低后升高的趋势,并最终将其超越。

Abstract: Influence of blending effect of two kinds of amphiphilic polymer,B-type and Haibo Ⅲ-type,for oil displacement on their emulsion stability and emulsifying power was studied with stability analyzer and optical microscope.With mobilometer,interface tensiometer and Zeta potential analyzer,rheological performance and interfacial characteristics of the two kinds of amphiphilic polymer as well as their blend systems were studied.Results showed that both separate kinds of amphiphilic polymer for oil displacement and their blend systems can form O/W emulsions.With the increase of B-type amphiphilic polymers,the size of droplets of the blend system emulsion lie between that of two kinds of amphiphilic polymer emulsions,and the size of the emulsion droplets decreases and the distribution become narrow.At the same time,the viscosities of external phases,oil-water interfacial tensions and the absolute values of Zeta potentials of different blend systems increase firstly and then decrease.Under comprehensive functions,the migration rate of droplets of the blend system emulsions decrease and the degrees of flocculation and coalescence increase firstly and then decrease.Comparing with the emulsions prepared by two kinds of amphiphilic polymers,stability of the emulsions prepared by their blend systems reduce firstly,and then increase to the highest value.

Key words: amphiphilic polymers, blend system, emulsification performance, stability, migration rate, interfacial activity, rheological performance
