摘　　要：为了研究掺柴WF稠油黏度的相关规律,将WF空白稠油分别掺入质量分数分别为5%、10%、15%、20%和25%的柴油,测试混合油在不同温度下的表观黏度,比较可能适用的黏度计算模型预测结果和实验数据,结果表明:Walther黏温相关式适用于描述掺柴稠油混合油的黏温关系,而Chirinos模型、Shu模型和Miadonye模型的计算结果不能满足实际工程需要;采用反算出的c值,Cragoe模型可以很好地用于掺柴WF稠油黏度的预测,平均相对偏差小于5%。基于此,提出了一种可靠而简便的适用于实际工程的基于Cragoe模型的掺柴WF稠油黏度预测方法。(图4,表2,参15)To identify the variation of viscosity of WF heavy oil mixed with diesel, blank WF heavy oil is mixed with diesel with different mass fractions of 5 %, 10 %, 15 %0, 20 % and 25 %, for purpose of measuring the apparent viscosities of blend oil at different temperatures. The test results are compared with the prediction results with applicable viscosity calculation models, indicating that Walther viscosity-temperature correlation is appropriate for describing the relationship between viscosity and temperature of the blend oil, while results of Chirinos model, Shu model and Miadonye model cannot meet the needs of the practical engineering. Using the back calculated c value, Cragoe model can be used for viscosity prediction of WF heavy oil mixed with diesel, and the average relative deviation is less than 5 %. Therefore, based on Cragoe model, a reliable and convenient viscosity prediction method for WF heavy oil mixed with diesel is proposed, which is applicable to practical engineering. （4 Figures, 2 Tables, 15 References）
