目前高含水期油田中使用的流体取样式电容法产出剖面测井仪因其精度低不能满足测量高含水油田含水率的要求. 为此,利用同轴线作传感器,使油水混合介质在同轴线内流动,通过测量油水混合介质的相位系数来得到油水混合介质的含水率. 研制的仪器不但提高了测量精度,还实现了油井含水率以往难实现的连续测量. 模拟井试验和现场试验结果表明了该油井含水率测量方法的新颖性及实用性.

Abstract : The difference in dielect ric property between oil and water is so great that their phase constant s of elect romagnetic waves are quite different . The mixture of oil/ water flows inside the coaxial line used as a sensor . The water content in the oil/ water mixture can be measured by measuring the phase constant . The measuring inst rument can improve the measuring accuracy of water content , and realizes continuous mea2 surement of water content in oil well. Simulation result s and on2site measurement s show this way of mea2
suring water content is new and practical.
Key words : water content ; coaxial line ; elect romagnetic wave ; continuous measurement
