| 摘 要： | 基于能量守恒原理，导出了描述天然气井井筒温度分布的常微分方程，根据此模型可得到井筒温度分布的解析解，显示井筒温度分布服从指数函数变化规律。计算结果表明井筒温度分布曲线的形状取决于天然气流量，反映了井筒内流动和传热特征。应用本模型可得到不同天然气流量条件下的井筒温度分布曲线，计算方法简便快捷，方便工程应用。

| Abstract: | Based on energy conservation principle, an ordinary differential equation were been proposed to describe borehole temperaturedistribution for ultra-deep gas well. Analytical solutions of borehole temperature distribution curve can be predicted by this model, which indicatedthat borehole temperature distribution curves follow a law of exponential function. The calculation results show that the shape of wellbore temperaturedistribution curves depend on natural gas flow rate, which can reflect the characterist... |
