摘要
本文针对实际生产中某油井或某计量站的原油和水的密度相对稳定的特点,通过测量含水原油的混合密度,推导出间接测量含水率的数学表达式,并对其测量原理、精度、干扰因素和适用范围进行了分析.
Through metering the mixed density of hydrous crude, the author deduced a mathematical expression formula which meters the water content indirectly. This article also analyses its metering precision, interference factors and applicable limits.
