摘　　要：建南气田南飞三气藏为弹性驱动的岩性-构造复合气藏,气层分布稳定,是以颗粒灰岩(鲕粒灰岩、砂屑灰岩等)为主的裂缝-孔隙型储层。通过对南飞三气藏各生产井产出水进行水分析,结合各产水井产水时间、产水快慢、产水量等生产动态情况及储层孔隙、裂缝的发育分布等静态情况,确定气藏地层水水线推进方向及目前水线大致推进位置,预测下步可能对生产产生的影响,并针对这些影响提出了合理的排水采气建议。Nanfeisan gas reservoir of Jiannan gas field is an elastic driving lithology-sturcture composite gas reservoir,where air layers distribution is stable.It belongs to fracture-pore type which consists mainly of grain limestone.This paper has analyzed production water of each production well in Nanfeisan gas reservoir.Based on the analysis and the development distribution of reservoir pore and fracture,it has determined propelling direction of the formation water of gas reservoir and its current position,and has proposed reasonable suggestions for water pumping and gas production by forecasting the possible impact on the next production.
