摘要

介绍了一种基于锥形螺旋传输线的油水两相流持水率传感器(CSTLS)。给出了描述电磁波在CSTLS上传播的传输线理论模型。数值模拟和实验结果表明，被测流体的持水率与传感器检测信号的相移近似成线性关系。在0% ~ 100%的含水率范围内，检测分辨率可达3%。

Borehole Water Holdup Detection Using Conical Spiral Transmission Line

A conical spiral transmission line-based sensor (CSTLS) is introduced to measure the water holdup in oil-water two-phase flows. The theoretical model of the transmission line is given to describe the electromagnetic wave propagation on the CSTLS. Numerical simulations and experimental results show the water holdup of the measured fluid is approximately linearly proportional to the phase shift of the signals detected by sensors. The detection resolution is up to 3% in the whole range of water holdup from 0% to 100%.
