摘　　要：文中综合旋流+膜分离技术于一体,设计了一种井下“旋流+亲油疏水膜”分离装置。对这种装置进行了样机实验和相关性能研究,确定了膜的最优结构形式、膜与旋流复合的最优形式。研究结果表明:当将亲油疏水膜与旋流耦合时,膜外不用安装罩时油水分离效果更优;当将旋流油水分离的出油口与膜分离后的出油口连接在一起时,在出水口分流比较小时膜的存在对于促进油水分离效果较明显,出水口分流比较大时膜对于促进油水分离效果较不明显。This paper designs a separation device of"cyclone+hydrophilic and hydrophobic film"by integrating cyclone+membrane separation technology.The prototype test and related performance research of the device are carried out,and the optimal structure form of membrane and the optimal combination form of membrane and cyclone are determined.The results show that when the hydrophilic membrane is coupled with cyclone,the oil-water separation effect is better without a cover installed outside the membrane.When the outlet of swirling oil-water separation is connected with the outlet of membrane separation,the effect of membrane on oil-water separation is more obvious when the outlet shunt ratio is small,but less obvious when the outlet shunt ratio is large.
