摘　　要：掺稀降黏是开采稠油的一种重要的井筒降黏工艺。基于能量守恒和动量守恒,建立了考虑井筒产液温度和压力互相影响的稠油掺稀井井筒流体温度-压力耦合数学模型,并用迭代法对控制方程组进行了求解,实例计算与对比表明模型准确度高。利用该模型对掺稀井井筒温度分布进行了计算与分析研究,分析了掺稀温度、掺稀比、掺稀深度等参数对井筒温度分布的影响。为掺稀降黏工艺参数的设计提供一定的指导意义。Diluting with light oil is one of the important technology to heavy oil recovery. An analytical model was derived to predict the wellbore temperature profiles for the heavy oil production assisted with the addition of light oil from the annulus. The model was based on energy balance between the formation and fluids flowing through each conduit. The temperature profiles were calculated using the proposed temperature model and results were compared with the measured data. Sensitivity analysis was conducted using the proposed model and main factors that influence the temperature profiles were discussed.
