微波法测量原油含水率计算公式的推导

Deduction on Equation of Water Ratio in Oil with Microwave Method

基于微波双参数法测量原油含水率的基本原理,通过建立油气水三相混合流体的复介电常数模型,研究了储能因子和损耗因子与混合流体密度的关系,给出了消除混合流体密度影响的原油含水率微波测量方法,推导了原油含水率与微波测量参数的函数表达式。

Based on the basic principle of microwave double-parameter method to survey water ratio in oil and by established oil-gas-water three-phase complex permittivity model,the relationship between energy storage factor and loss factor with the density of mixed liquid is studies.The microwave transmission method for water ratio in oil that can eliminate density influence for the mixed liquid is given,and function expression for water ratio and microwave transmission parameters is deducted.
