摘　　要：为了给稠油输送管线的优化和节能技术的研究提供基础数据,对欢喜岭稠油的黏温特性和流变特性开展了实验研究。绘制黏温曲线和流变曲线并拟合稠油的黏温方程和流变方程,计算了各温度区间内的黏温指数。对黏温曲线和流变曲线进行分析发现,曲线的相关系数R2接近于1,说明拟合程度较高,误差较小;流变指数均小于1,说明实验所用稠油为假塑性流体;当温度高于70℃时,可将稠油视为牛顿流体。In order to optimize the transportation pipeline of heavy oil and provide baseline data for the study of energy-saving technology,the experimental study on the viscosity-temperature characteristics and rheological properties of heavy oil in Huanxiling was carried out.The viscosity-temperature curve and the rheological characteristic curve were drawn,the viscosity-temperature equations and the rheological equations were fitted,and the viscosity-temperature index was calculated at each temperature interval.Through the viscosity-temperature curve and rheological characteristic curve fitting,the results showed that the correlation coefficient was close to 1 which indicated a higher degree of fitting and the small error.The rheological index was less than 1,which indicated that the heavy oil used in the experiment was pseudo plastic fluid.At the test temperature of 70 ℃,the heavy oil showed Newtonian behavior.
