摘　　要：从生产需要出发 ,根据传热学的基本原理 ,分析了井筒管柱系统的热阻 ,通过假设 ,简化井下的复杂情况 ,应用能量守恒定律 ,建立了热平衡的自喷井流动温度微分方程数学模型 ,并利用边界条件给出了方程的解析解。模型计算与现场实测的动态温度值相比较 。In this paper, the thermal resistance of the pipe system is analyzed from the requirement of the practical produce condition and from the basic theroy of heat transfer. With some assumptions the complication down hole is made simple. The heat balance differential equations of the blow well flowing temperature are set up with energy conservation rule. And the analytical solution are solved with boundary conditions. A good job of prediction is get when the model calculation is compared with the development temperature.
