摘　　要：苏里格气田目前投产气井5000余口,揭示气井生产动态特征,为气田稳产技术的制定奠定坚实的基础。目前气田实际生产数据分析表明,气井压力变化表现出明显两段式特征,生产初期压力下降快,后期由于外围供给,压力下降趋势明显减缓,即低压下气井具有较长生产期;同时,气井压力与时间、产量与时间均呈明显指数关系。气井1/t、1/Gp关系曲线具有较好的线性关系,气井产量递减符合指数递减规律。Sulige gas field now has more than 5 000 production well, revealing the dynamic characteristics of well production can build stable foundation for formulating policy of stable production. The analysis of actual production data indicates that the pressure changes show obvious two features, the initial pressure droped fast, as the external supply, the pressure downward trend slowed down significantly,and the gas well has a longer production period in low pressure; simultaneously, the pressure changes with time and the yield with time has a significant exponential relationship. 1/t, 1/Gp curves have a preferable linear relationship, the decline of yield meet the exponential decline.
