摘　　要：通过阻抗传感器在垂直小管径实验装置中进行油/水两相流动态模拟实验,利用动态信号分析仪采集不同流量及不同含水率下的阻抗输出电压信号,对实时采集的电压信号进行了分析,首次采用面积法及功率谱的方法对电压信号进行阻抗特性分析。实验结果表明:低流量和高流量时的电压信号阻抗特性具有明显的差别。通过阻抗分析建立了面积特性及最大功率谱幅值特性与含水率及流量的关系。Dynamic calculation experiments of impedance sensor in oil/water two-phase flow are carried out on vertical small diameter multiphase simulation well.The voltage fluctuation signals of impedance sensor are sampled in the case of different flowrate and different water cut.The voltage fluctuation signals are analyzed,and the impedance characteristics of voltage signals are analyzed by the method of area method and power spectrum method.The analysis results show that the impedance characteristics of voltage signals with low flowrate are identifiably different to high flowrate.The relationships of area characteristics and power spectrum with flowrate and water cut are built through impedance analysis.
