文中对影响气井产量递减的因素进行分析，在不同类型递减气藏中选出一批井，根据油气井递减基本规律，进行产量回归研究，得到一些新的认识，即四川气田大多数气井产量递减不仅符合指数递减，同时也符合双曲线递减；在产气量预测中，双曲线预测结果好的井几乎为气水同产井，指数式预测结果好的井几乎为纯气井，这将为四川气田气井以后的产能预测工作起到积极的指导作用。

The paper analyses the factors which effect production decline in gas well. On the basis of basic law of oil/gas well production decline, the regression research of production is done. The research results show that production decline of gas well not only conform to index decline, but also conform to hyperbolic decline. In production forecast, good well for hyperbola forecast result is water- bearing gas well, good well for exponential forecast result is net gas well. The forecast result has positive act on productivity forecast in Sichuan gas field.
