Abstract: Based on coupling wellbore and reservoir, the forecasting-productivity model of the horizontal wells were presented by Duan Yong-gang and Chen Wei, and that Cinco’s method to calculate transient pressure of finite conductivity vertical frac-tures well, this paper found a predicting productivity calculation
model and formulas in Laplace space, for the convenient and the practicality to apply in oil field.Therefore, it could apply a great deal of existent flow models of the horizontal wells and it’s pressure solution in the reservoir models. By iterative solution,some important information would be obtained such as the flow flux and pressure drop in wellbore etc.

Key words: horizontal well, performance prediction, tran-sient, coupling
