摘要:
通過測量含水原油介電常數間接測量原油含水率是一種常用的方法。分析傳輸線上電磁波的傳播特性,推導在混合波工作模式下傳輸線終端電磁波幅度和相位與介電常數的關系,通過數值模擬說明基于電磁波幅度特性檢測介電常數方法的不可行性;基于電磁波相位特性檢測介電常數的可行性。選擇合適的傳輸線負載,即便在混合波模式下,也可以通過檢測電磁波在傳輸線上的相移而獲取傳輸線內流體介質的介電常數。
Abstract:
The general way of measuring the water holdup of oilwater mixture is to measure the dielectric constant of the mixture. Analyzed are the propagation characteristic of electromagnetic wave on coaxial line, derived is the relationship between the dielectric constant of the mixture in the coaxial line and the amplitude/phase of electromagnetic wave at the end of the coaxial line under hybrid wave mode, based on which related numerical simulations are performed. The researches show that the method based on the amplitude change of the electromagnetic wave isn’t feasible for measuring dielectric constant, but it can be measured by the phase change if one reasonable load of the coaxial line be connected.
