Abstract A gas-liquid mechanical model as well as a thermal model which consider the effect of the
temperature and pressure on properties parameters are established for the annulus flow in the deep well
in this paper. Afterwards, with the models, the hydraulic and thermal characteristic of a well with a
depth of 5000 m is analyzed. Re
