摘　　要：对近年来原油中环烷酸结构组成的研究进展进行了综述,从环烷酸的结构、相对分子质量、环烷酸在不同水相环境(不同酸碱度、不同盐溶液)以及环烷酸与原油活性组分(沥青质、石蜡)相互作用等方面对原油乳状液稳定性的影响进行了总结。分子结构和相对分子质量会影响环烷酸在油水界面的吸附行为从而影响乳状液稳定性;而不同水相环境会影响环烷酸的HLB值和界面活性从而影响乳状液稳定性;原油中的活性组分沥青质、石蜡与环烷酸相互作用也会影响环烷酸在油水界面的吸附及排布机理从而影响原油乳状液稳定性。The latest research on structure of naphthenic acid was summarized. Effect of naphthenic acid on stability of crude oil emulsion was concluded based on structure, relative molecular weight, different aqueous environment （different pH, different salt solutions） and the synergy effect of naph- thenic acid and crude oil active ingredients（including asphaltenes and paraffin）. Different structure and relative molecular weight of naphthenic acid generate different absorption performanceat O/W in- terface which will impact stability of crude oil emulsion. HLB value and interracial activity of naph- thenic acid in different aqueous phase will effect on stability of crude oil emulsion. Synergy effect of naphthenic acid and crude oil active will effect on stability of crude oil emulsion through the mecha- nism of absorption behavior and molecular arrangement.
