THE MEASUREMENT OF PHASE FRACTION OF OIL/AIR /WATER THREE-PHASE FLOW BY USING OPTICAL FIBER AND IMPEDANCE PROBE

将光纤探针和电导探针应用于油气水三相流截面相份额的测量中，提出了油气水三相流动截面相份额光纤探针／电导探针的组合测量技术，并用这种技术成功地测量了垂直上升管内油气水三相流动的局部和平均截面相份额。试验表明，这种技术具有简单易行、响应快、精度高等优点，是测量油气水三相流动局部截面相份额和平均截面相份额的一种有效方法。

Anew complex measuring technique using optical fiber andimpedance probeshas beendeveloped to measure phase fraction of oil/air/water three-phase flow, The local and meanphase fractions of oil/air/water mixture in vertical upward flow were measured.The experi-ments show that this method is an effective method to measure phase fraction and has manyadvantages,such as fast response,high accuracy,and simple and easy operation.
