Abstract: In accurate calculation of gas viscosity and compressibility factor z, an empirical formula for the pseudo-pressure calculation of real gas at a constant temperature is presented, and the converted curves from pressure to pseudo-pressure and the single well productivity equation for deliverability test are given. The case study in Cai-31 gas reservoir shows that its gas well performance prediction by these formula and equation is better in effectiveness.

Key words: gas field, real gas, pseudo pressure, empirical formula
