摘　　要：　研究了煤油与原油配制模拟油乳状液的稳定性,应用显微镜测定了模拟油乳状液粒子的粒径.实验确定了配制模拟油乳状液的最佳原油与煤油比、乳化速度、乳化时间和油水比.对破乳剂OX-9354和OX-9351在模拟油与原油乳状液中的脱水情况进行了对比,表明脱水率变化趋势相同,模拟油可以用来评价破乳剂.<Abstrcat>A simulated crude-oil is made up by using kerosene and crude oil.Emulsion's stability is (studied,a) simulated emulsion's the size and distribution of droplets were measured by the microscope , which the average droplets diameter of the stable emulsion is about 1μm , then the optimal crude-oil kerosene ratio ,the emulsified velocity ,the emulsified time and oil-water ratios are determined.A comparison of dewatering percentage from the simulated emulsion and crude-oil emulsion for the demulsifier (OX-9354 and ) OX-9351 is performed, the same tendency shows that the simulated emulsion can be used to appraise demulsifier.
