混合原油粘度计算模型

高粘原油降粘通常采用稠油与轻质原油混合输送的方式。针对目前混合原油粘度的计算还没有普遍适用的粘度计算模型问题,通过参考各种文献,给出了常用的混合原油粘度计算式及其适用范围。以吐哈—南疆—北疆(重质油)混合原油为例,给出了粘度模型筛选过程,从而为实际应用提供了参考。

An Available Viscosity Calculation Model for Mixed Crude Oil

Highly viscous crude oil is commonly transported with mixing technique (heavy crude and light crude) in order to reduce viscosity. However, the viscosity calculation model available to the mixed crude oil remains to be developed. Based on the publications and information,the author develops a viscosity calculation model for mixed crude oil and points out its available scope. Take the Tuha-Nanjiang-Beijiang (heavy crude) mixed crude oil for example, the article introduces the screening course of viscosity calculation models which provides a reference for actual application.
