摘要： 建立了模拟气井内天然气向地面流动时其热力参数沿流程变化规律的模型。据此模型探讨了对天然气井实施保温措施的方案,并预估了采用某些保温措施的效果。

Abstract: A model for simulating the flow and heat transfer in natural gas well bore was established by using the basic principle of gas dynamics ,heat transfer and thermodynamics. The predicted results from this model were in good agreement with the measured values. Two heat insulation methods to avoid forming natural gas hydrate which will obstruct the flow of natural gas were discussed. The results showed that in order to increase the exit temperature of natural gas the heat insulaton coating should be applied on the outside of well bore rather than filling nitrogen into the annulus between well bore and casing.
