Shan-2 gas reservoir of yu-lin gas field is a closed and normal pressure gas reservoir without edge and bottom water. As one gas source of the project of "west-to-east gas pipeline", it is very necessary to predict the production performance of Yu-Lin gas field. A new mathematical model with supplementation is given for predicting the production performance of a closed gas reservoir. In this model, gas production compensated caused by the heterogeneity of gas and the differences in pressure was considered. Using the model, the production performance of gas well in southern areas of yu lin gas field. The predicted results show that, this model can estimate the output of gas wells during the stable production stage, the declining stage.and predict the major production data, such as well bottom-hole pressure, formation pressure and recovery ratio. The model can predict the years of stable production of gas well in differtent proration production, which is a foundation to adjust the gas field development project and has important sence for efficient developing of gas field.
