摘　　要：为探究油田采出液温度对油水分离旋流分离器(简称旋流器)性能的影响,采用数值模拟与试验验证相结合的方法,研究不同温度下旋流器分离流场内的流动参数、油相分布、油水分离效率的变化规律。结果表明:随着采出液温度升高,分离流场中油水混合物的切向速度、压力、湍动能以及油滴粒子的径向沉降速度均增大,旋流器的分离性能提高;随着采出液温度升高,旋流器轴心处油水混合物中油相体积分数提高13.97百分点,油相体积分布非均匀度降至80%以下,油芯平均直径减小0.16 mm,轴心处的油相富集程度提高,分布均匀;当采出液温度高于70℃时,旋流器分离效率达99%以上。In order to explore the influence of produced liquid temperature on the separation performance of hydrocyclone for oil-water separation(referred to as hydrocyclone),the parameters of the flow field,oil phase distribution and the separation efficiency of hydrocyclone were studied by the method of experiment and numerical simulation.The results showed that,in the research range,the tangential velocity,pressure and turbulent kinetic energy of the mixture in the separation flow field and the radial settling velocity of oil drop were positively correlated with temperature.The increase of the tangential velocity,pressure and the radial settling velocity improved the separation performance of hydrocyclone.Moreover,with the increase of produced liquid temperature,the volume fraction of oil in the axis was increased by 13.97 percentage points,the non-uniformity of oil phase volume distribution was decreased to less than 80%,the average diameter of the oil wick decreases by 0.16 mm,and the enrichment degree of oil phase at the axial was also increased.Ultimately,when the produced liquid temperature was higher than 70℃,the separation efficiency was more than 99%,and the separation performance of hydrocyclone was the best.
