摘　　要：为分析高含水超稠油乳状液的析水特性,对乳状液油水分离过程中不同层位的油水两相体系进行了显微观测和黏度分析,确定了不同层位分散相的粒径分布及体系黏度的变化规律,从微观上对油水分离机理进行了描述,以锦45区块为例,分析了高含水期集输管道水漂油分层流动状态的形成过程。In order to analyze the characteristics of the precipitated water of emulsion with high water super heavy oil,two phase system of oil and water in different layers was observed by microscope and its viscosity was analyzed in the oil-water separation process. Particle size distribution of the dispersed phase in different layers and the viscosity variation was determined. Oil water separation mechanism was described from the microscopic. Take the Jin 45 block as an example,formation of stratified flow of gathering and transportation pipeline in the high water period was analyzed
