摘　　要：三元复合驱是一种重要的驱油技术,但三元成分复杂,给采出液的处理增加了难度。针对原设计的用于水驱采出液处理的三相分离旋流器,采用Fluent软件,进行了不同黏度变化对三相分离旋流器压力特性和脱气除砂效果影响的数值模拟分析。结果表明,随着黏度的增大,旋流器除砂出口压力损失逐渐增大,分离效率呈降低趋势,脱气除砂效果均受到影响。若用于高黏度介质的处理,必须对现有三相分离旋流器结构进行改进设计。ASP（alkali,surfactant,polymer）flooding is a main flooding technology,while it makes the treating of produced fluid be more difficult.Focused on original three-phase separation hydrocyclone used for water-flooding produced fluid treating,by using Fluent soft pack,numerical simulation analysis for the effect of viscosity on pressure characteristics,de-gas and de-sand efficiency of the hydrocyclone was carried out.Results show that with the rise of viscosity,pressure drop of sand outlet increases.The effect of de-gas and de-sand was affected.Therefore, hydrocyclone＇s structure must be revised for the high-viscosity produced fluid treating.
