摘要:
庄海军等.集流型流体电容含水率计低流速测量原理.测井技术,1995,19(6):411~415本文详细分析了用于生产测井中测量油、水两相流含水率的集流型流体电容含水率计在低流速下的测量原理。由于低流速时内电极表面的亲油性以及轻质相的油在垂直管道中趋于中心向上流动(气液两相在垂直管道中向上流动时,气相趋于中心向上流动[2],故本文有此推论),集流型流体电容含水率计在低流速情况下,含水率以对数的形式改变仪器的响应频率。低频下,流体中的水以等势体的形式改变电极间场强分布,从而等效成外电极内径的改变。按照这一测量原理,低流速情况下,仪器在0%~100%含水率范围内均有油、水分辨能力,并且随含水率的增加,灵敏度逐渐增大。静态与动态实验均与新的测量原理相符,这对该仪器在低产液并测井中的应用具有重要指导意义。
