| 摘 要： | 论述了一种新型的油井持水率测定方法。它采用基于折射率调制的光纤传感技术，可避免传统电容法的不足。其持水率测定范围从０％￣１００％，精度〈１％。详细分析了这种传感器的特性，指出对于特定的外界折射率范围，需设计纤芯折射率、光纤半径、弯曲半径三个参量的最佳组合。

| Abstract: | A new method for measuring the borehole water holdup is given in this paper.It uses fibre-optic sensing technology based on refractive index modulation and has some advantages over conventional capacity method. The water holdup measured by this sensor ranges from 0% to 100% and its precision is lower than 1%. The characteristics of this sensor is analysed. It is concluded that for a certain refractive index range, the index of fibre core, the radius of core and bending radius need to be optimized. |
