摘要
本文根据高频电磁波的谐振特性测量原油含水率(0～100％)的原理,研制出一种短波型井下找水仪传感器。该传感器输出一个相应于石油含水率的电压信号,由此可测量出原油的含水率。文中还介绍了井下找水仪传感器的原理,特性及其应用。并对影响环空井下找水仪测量误差的因素进行了分析。
According to the principle for measuring th 鈥?percentagewater content in crude oil (0-100%) by means of the resonant characteristic of high-frequence electromagnetic wave, a short-wave type sensor was designed and developed. It can provide a voltage output signal in accordance with the percentage of water in crude oil. The principle of short-wave type sensor, property and a water detector for annular log are introduced in this paper. The measurement errors and the effective factors on errors are analyzed.
