摘　　要：基于热量传递原理和多相流动理论,建立了电加热降粘工艺下产液沿井筒流动与传热的热力学模型,计算了产出流体沿井筒的温度分布,并利用现场实测数据,验证了模型的准确性。利用该模型,模拟计算了不同加热深度、功率以及加热位置下产出液的温度分布,分析了各参数对电加热井流体温度分布的影响,提出了基于温度分布模拟下选择电加热参数的方法。Based on the theories of heat transfer and multiphase flow,the thermodynamic model is established which accounts for the wellbore flow and the heat transfer between the crude and formation.The temperature distribution along the wellbore of the production fluid is calculated through the model,and the accuracy of the model was verified by using the measured data.The production fluid temperature distribution is calculated under different heating depth,heating power and heating position.The influence factors of the temperature distribution have been analyzed on the electric heating well.At last,we propose a method of electrical heating parameters chosen based on the temperature distribution simulation.
