相位法原油含水率测量系统

针对电磁波在油水混合介质中传播时，其相位会随混合物中含水率的不同而发生变化这一特点，介绍了通过检测电磁波信号的相位变化实现原油含水率测量的系统.应用100MHz高频电磁波信号，采用同轴线作为传感器，实现了0%～100%含水量的连续测量.给出了以10%含水率为间隔点的测量结果.实验表明，该系统适合应用于高含水阶段(60%～100%)的原油含水率测量，测量结果稳定，测量误差在2%以内.

Measurement system for water cut in crude oilbased on phase method

When electromagnetic wave travels in oil-water mixture medium,its phase vary with water cut in the mixture due to obvious difference in dielectric constant between oil and water.In accordance with the above characteristics,a measurement system for water cut in crude oil was developed through detecting phase variation of electromagnetic wave.Using 100 MHz high-frequency electromagnetic wave and taking coaxial line as sensor,the continuous measurement for water cut from 0% to 100% was realized.The measured re...
