Abstract: Based on drift model which copes with gas-liquid phase slippage and non-uniform distribution along section of wellbore,a coupled temperature-pressure prediction model was established for varied angle gas wellbores considering momentum conservation,conservation of energy and wellbore heat transmission. The model was validated with 15 tested gas wells. The calculation showed satisfying results with average absolute error of 3. 6% which meets engineering requirements.

Key words: multi-phase flow, drift model, temperature, pressure, tight sandstone gas wells
