原油密度测定应注意的几个问题

Several Problems that should be Paid Attention to in the Determination of Crude Oil Density

我国原油贸易结算依据为油品在空气中的质量,因此,密度是原油计量工作中非常重要的参数之一,它不仅直接参与油量计算,一些重要的修正系数也与它有关。本文结合目前最常使用的石油密度计法,通过大量实验,分析了影响密度测定的主要因素,并提供了减小密度测定误差的方法。

China's crude oil trade settlement is based on the mass of oil products in the air.Therefore,density is one of the most essential parameters in crude oil measurement.It not only directly participates in the calculation of oil volume but also has some critical correction factors related to it.This paper combines the most commonly used petroleum density meter method,through a large number of experiments to analyze the main factors that affect the density determination,and provides a method to reduce the density determination error.
