摘　　要：通过界面张力仪、TURBISCANLAB稳定分析仪及微分干涉显微镜对甜菜碱表面活性剂及其聚表体系的稳定性进行研究。研究表明:原油乳状液稳定系数与聚合物浓度成反相关;多重光散射原理的基础上应用TURBISCANLAB稳定分析仪从动态上反映乳状液颗粒从稳定到失稳的过程;结合微分干涉显微及驱油实验提出了一种综合评价乳状液稳定性的方法。In this paper, the stability of betaine surfactant and its polymerization system were studied by means of interfacial tension meter, TURBISCANLAB stability analyzer and differential interference microscope. The research shows that the crude oil emulsion stability coefficient and polymer concentration is inversely related; multiple scattering based on the principle of application of TURBISCANLAB analyzer reflect the failure process of stability from stable to emulsion particles from dynamic; combined with differential interference microscope and oil displacement experiment and puts forward the method of emulsion stability of a comprehensive evaluation.
