摘　　要：根据国内外近年来对稠油乳状液稳定性的研究,综述了水包油型稠油乳状液稳定性的影响因素。介绍了水包油型稠油乳状液的形成以及油水界面膜性质,油水界面膜的强度在很大程度上决定了水包油型乳状液的稳定性。其次综合分析了稠油乳状液的动态稳定性与静态稳定性,含水率、乳状液粒径分布、乳化温度、界面张力、矿化度以及化学添加剂都对水包油型稠油乳状液的稳定性存在一定的影响。最后简介了基于聚焦光束反射测量仪的乳状液粒径分布测量,为研究稠油乳状液的动态稳定性提供一定的参考价值。Based on the recent studies on the stability of heavy oil emulsion at home and abroad,the influencing factors of the stability of oil-in-water heavy oil emulsion were reviewed.The formation of oil-in-water heavy oil emulsion and the properties of oil-water interface film are introduced.The strength of oil-water interface film largely determines the stability of oil-in-water heavy oil emulsion.Secondly,the dynamic stability and static stability of heavy oil emulsion were comprehensively analyzed.Water content,particle size distribution of emulsion,emulsification temperature,interfacial tension,salinity and chemical additives all have certain influence on the stability of oil-in-water heavy oil emulsion.The measurement of particle size distribution of emulsion based on focused beam reflection measuring instrument is introduced,which provides a certain reference value for studying the dynamic stability of heavy oil emulsion.
