【摘要】 总结了见诸文献的石油粘度关联模型,分析了各种类型石油粘度的影响因素,评述了各类模型的优点和不足。认为在关联预测石油粘度,尤其是高蜡、胶质和沥青质含量石油时,由于石油的非牛顿性表现很明显,必须综合考虑石油的组成、温度、压力、溶解气、石油的乳化状况、水含量等因素才能作出比较准确的关联。更多还原

【Abstract】 The correlation models of crude oil viscosity were reviewed. Its influence factor was analyzed.Advantage and deficiency of the models were compared. In the case of petroleum containing vast of wax or heavy fractions,such as resins and asphaltene,when non-Newtonian behavior is evident,the following factor,such as composition of the crude,temperature,pressure,dissolved gas,state of the crude emulsification,content of water etc, should be were taken into account for a accurate correlation.更多还原
