混合原油黏度特性测定与分析

Determination and Analysis of Viscosity Properties of Mixed Crude Oil

在原油顺序输送过程中会产生一定量的混油,混油段的长度及特性不断发生变化,为了更好地研究其变化规律,有必要对混油的黏度特性进行测定与分析。选取大庆原油和俄罗斯原油油样进行混合原油黏度测定与分析,并拟合出了混合原油黏度计算公式,对比结果表明,拟合公式计算精度较高。

A certain amount of mixed oil is always produced in batch pipeline transportation. And the length and characteristics of the mixed oil section change constantly. In order to study its change law better, it is necessary to measure and analyze the viscosity characteristics of mixed oil. In this paper, viscosity determination and analysis of mixed crude oil from Daqing crude oil and Russian crude oil samples were carried out. And a formula for calculating viscosity of mixed crude oil was worked out. The comparison results showed that the calculation accuracy of the fitting formula was high.
