中文摘要:
      考虑旋流分离器应用于井下,径向尺寸受限,影响其能量损耗。针对井下同井注采系统中旋流分离器的结构形式,建立了室内试验工艺流程,通过试验研究发现流量和分流比增加,旋流分离器的压力损失增大,但小锥段仍为主要分离段,仍可保证旋流分离器的分离性能;在满足工艺要求的前提下,分流比越小越好;对比不同流道型式的入口得出,当径向尺寸减小时,渐变截面直线型入口更利于旋流器能量的分配,降低了不必要的压力损失。
英文摘要:
      The smaller radial dimension and its influence on the loss in energy are considered, when the hydrocyclone is applied to downhole. To study the pressure characteristics of hydrocyclone applied to the injection-production system for the same well, the indoor test process flow is built up. Tests have shown that the pressure loss is increasing and the small cone section is still the main separated section with the accrescent flow and split ratio. The split ratio is lower as small as possible on condition that the technological requirements are fulfilled. In comparison with the inlets with different channel types, when the radial dimension is decreased, the hydrocyclone, which has the inlet of beeline channel type with changing sections, can allocate the energy more reasonably and decrease the unnecessary pressure loss.
