摘　　要：为探究气体对井下油水旋流器性能的影响规律,针对新型螺旋流道倒锥式旋流器,采用Fluent软件对气液比分别为0.01、0.03、0.05、0.08、0.10时旋流器的油相分布进行模拟分析。通过对比分析发现:不含气时旋流器的分离效率为89.31%;在结构参数和分流比不变的条件下,旋流器分离效率随气液比的增加呈降低趋势,气液比为0.10时,分离效率为36.90%;气液比越大,溢流口的油相体积分数越小,底流口的油相体积分数越大;溢流口和底流口的压力损失随气液比的增大而递减。In order to explore gas content＇s influence on the performance of oil-water cyclones underground,the Fluent software was employed to simulate and analyze cyclone＇ s oil phase distribution when gas-liquid ratio stays at 0.01,0.03,0.05,0.08 and 0.10,respectively.Comparative analysis shows that cyclone＇s separation efficiency can reach 89.31％ when no any gas can be found there; and the cyclone separation efficiency decreases with the increase of gas-liquid ratio; and for a gas-liquid ratio of 0.10,the efficiency can reach 36.90％ ; higher gas-liquid ratio brings about smaller oil phase volume fraction at the overflow port and higher oil phase volume fraction at the underflow port,and the pressure loss at both overflow and underflow ports decreases with the increase of gas-liquid ratio.
