| 摘 要： | 基于介电常数法测量原油含水率,往往受油水两相流态、温度、矿化度、非线性特性等多因素的影响.因此,设计一套基于多传感器的油水两相流实验室模拟系统,利用理论计算结合数值模拟的方法,研究含水率、温度、矿化度、油水介电常数、含水测最传感器输出之间的数学关系及影响规律,对提高测量含水率的精度提供了有力的理论和实验依据.

| Abstract: | The measurement of water content in crude oil based on the method of dielectric coet~cient is affected by multi-factor,inclu- ding flow states of oil/water,temperature,salinity content,non-linear character,etc.A measuring system based on multi-sensor is de- signed for oil/water two-phase flow experiments,the mathematic relations and influencing rules between water content,temperature, salinity content,dielectric constant of oil-water mixture,and output of water-measuring sensor are researched by numerical simulation combining with theoretical computation,some forceful theoretical and experimental references for realizing high precision measurement of water content is provided. |
