摘　　要：为保证导叶式水力旋流器稳定、高效运行,对其结构参数和运行时的操作参数进行了优选试验,并对物性参数进行了分析。试验确定了该旋流器锥段最佳锥角为5°,导流叶片最佳结构为叶片数n=4,叶片出口角β=20°,流道宽度w=3.47mm。试验结果还表明,在一定范围内,分离效率随入口流量的增加而增加,且随分流比的增加而增加,但二者并非越高越好;密度、粒度越大的颗粒越有利于分离,且旋流器并非适用于所有固体颗粒的分离;所设计的旋流器对井下多相分离系统中砂的分离是可行的。To ensure the stable and high-efficiency operation, the structural parameters and operating parameters of guide vane hydrocyclone are optimized and tested, and the physical parameters are analyzed. The optimal cone angle of the cone section of the hydrocyclone is 5°, and the optimal structure of the guide vane is vane number n=4,vane outlet angle β=20° and channel width w=3.47 mm. Within a certain range, the separation efficiency increases with the increase of inlet flowrate and also increases with the increase of separate flow ratio. But the two are not as good as they are high. The particles with higher density and granularity are beneficial to the separation. The test proves that the designed hydrocyclone is feasible to separate the sand in the downhole multi-phase separation system.
