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 show that in order to increase the exit temperature of natural gas the heat insulation coating should be applied on the outside of well bore rather than filling nitrogen into the annulus between well bore and casing.
