连续气举条件下气液两相流流型的研究

The investigation of gas-liquid two-phase flow patterns on the condition of continuous gas-lift

文章以奥齐思泽斯基流型分类公式为基础 ,对我国气举井中的气液两相流流型进行了较为全面的分析计算。由计算结果可以看出 ,目前气举井中只存在 2种流型 ,即泡状流和段塞流 ,且段塞流普遍发生在注气点以上 ,因此 ,从应用角度来说 ,可以不考虑过渡流和雾状流 2种流动型态 。

Based on the Orkiszewski’s flow pattern formulae,this paper gives a comprehensive investigation on flow patterns in gas-lift wells in China.The results show that there only exist bubble flow and slug flow in gas-lift wells,and slug flow occurs above gas-injection point.So the study of bubble flow and slug flow should be strengthened regardless to transition flow and mist flow.
