摘要
重油粘度在动力学计算以及其它物性估算方面是一个十分重要的性质,目前文献提供的估算方法和常规的粘度测定方法误差较大,因此有必要在其它物性和粘度间建立新的关联式。通过回归分析,在分子量、密度、残炭这些能够准确测定的性质与粘度之间建立关联方程,该方程用于估算特定的重油馏份准确性很高。
It is necessary to correlate the viscosity of heavy oil fractions with other characteristics because the viscosity is an important property in the calculation related to fluid flow and estimation of other physical properties. The available methods in the literature are less accurate at present. The new viscosity correlation with specific gravity, molecular weight and residue carbon is set up. The equation is fairly accurate to specific group of heavy oil fractions.
