摘　　要：为了优化稠油输送管线并为节能技术的研究提供基础数据,对稠油的黏温特性及流变特性进行了实验研究。运用MATLAB软件拟合了稠油的黏温方程和流变方程,并用Origin 8.0绘图软件绘制了黏温曲线和流变曲线。对拟合的黏温曲线及数据进行分析的结果表明,表观黏度的计算值与实验值的相对误差较小;对流变特性进行分析的结果表明,温度为50～80℃时冷家稠油表现为牛顿流体的特性;对所拟合的曲线进行了误差向量的2-范数检验,检验结果可知拟合曲线与实际情况的吻合度较高。In order to provide basic data for optimization of the heavy oil conveying pipeline and research of its energy saving technology, the heavy oil viscosity-temperature characteristics and the rheological characteristics were done for the experiment research. The heavy oil viscosity-temperature equations and rheological equations were fit by Matlab software and the viscosity- temperature curve and the rheological-temperature curve were drawn by Origin 8.0 software. The analysis results of fitting viscosity-temperature curve and its data show that the relative error is smaller between the calculated value of apparent viscosity and the experimental value; the analysis results of the rheological characteristics show that LengJia heavy oil assumes the characteristics of the Newton fluid between 50 ℃ and 80 ℃ ; Inspection of the 2-norm of error vector of the fitting curve indicates that the fit of the fitting curve with the actual situation is good.
