| 摘 要： | 根据原油含气时其介电常数变小的原理，分析了油气混合介质的相对介电常数与含气率的关系。采用半圆形电容器作为非接触式敏感探头来测量原油含气率，可以在线实时自动平均取样，消除了探头的安装位置和管道方位对测量结果的影响，使含气率的测量范围扩大到0－100％。

| Abstract: | When the oil contains gas, the dielectric constant decreases. A sensor with semi-circle capacitor is adopted to on-line automatically and averagely measure the void fraction of crude oil. The on-line uncontact measuring method can eliminate the influence of the fixing direction of sensor on the pipe,and enlarge the measure range from 0 to 100%. |
