Abstract
Results show that: (1) The SNG temperature in annuli has an increase at the heel-point due to heat conduction from IT to annuli. (2) When the mass injection rate is kept unchanged, the SNG temperature at a certain place in annuli decreases with increasing of the mass content of non-condensing gases. (3) The SNG in IT undergoes phase change into saturated state at the distance of 150 m. Then, from the distance of 150 m-200 m, the gas content in the mixture system gets an increase and the superheat degree is equal to zero. (4) Phase change occurs again in annuli when the SNG reaches the distance of 110 m where the wet fluid turns into superheated state, after which the superheated degree of SNG increases continuously as SNG is flowing to the heel-point.
