摘　　要：在一定的温度和压力下 ,天然气中所含有的水会形成凝析液 ,如果不能及时排出井口 ,则会在井底形成积液 ,导致气井不正常生产。因此 ,研究凝析液的数量对于制定合理的气井工作制度 ,维持气井的正常生产具有现实的意义。从计算天然气的含水量出发 ,计算气井的凝析液量 ,分析凝析液量随井口压力和气层压力的变化关系。模拟一口实例气井的产水曲线 ,从而论证提出的计算凝析液量方法的合理性 ,对于预测气井的凝析液量具有一定的指导意义。The water content of natural gas will be condensated in form of liquid under certain temperature and pressure,if the condensate liquid can not be removed form bottom bore to wellhead,it will accumulate in the bottom bore,production of gas well can not normalize.Therefore,it is important that study production of condensate liquid for holding normal production of gas well.On the basis of calculating the water content of natural gas,production of condensate liquid is calculated and its change with the temperature and pressure is analyzed.Production water curve of a gas well is simulated,rationality of production calculation of condensate liquid is demonstrated in this paper.
