| 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. |
