摘　　要：普光气田为超深高酸性气田。由于天然气组分的特殊性，气田开发过程中动态监测面临很多问题，给现场气井产能计算带来困难。“一点法”经验产能公式方法简单，现场应用方便。本文在已有测试数据的基础上，力图总结出适用于普光气田气井产能预测的改进“一点法”公式．预测普光气田气井的产能；同时将气井类型曲线法和采气指示曲线两种合理产量确定方法应用于气井配产，并结合气田生产实际，总结出气井的经验配产方法，指导气田气井确定合理产量。Puguang Gasfield is ultra-deep and highly acid. Due to the special composition of the natural gas, the gasfield perfornlanee monitoring faces a lot of problems, and brings difficulties to calculation of the gas well productivity. An empirical productivity formula of ＂single-point method＂ is a simple and convenient method. On the basis of exiting testing data, the authors try to summarize the improved empirical formula of ＂single-point method＂ that is applicable to the gas well productivity forecast of Puguang gasfield. The two reasonable production-rate determination methods of gas well type curves and gas recovery Index-curve methods were applied to the proration allocation of the gas wells. Combined with the actual production of the gasfield, empirical proration allocation methods of gas wells are summed up, giving guidance for determining the reasonable production rate of gas wells.
