摘　　要：气井出水是气田生产后期面临的一个较严峻的问题,气井出水大大减少了气田的采收率。由于堵水采气和排水采气对于海上气田来说作业成本极高,因此研究带水采气措施具有重要的意义。本文结合某海上气田出水井A9井的实际情况,通过计算气井稳定携液生产的微正流量以及气液两相流流过油嘴阀芯的能量损失来采取相应的延长出水气井寿命的措施,为延长海上气田出水井寿命,提高其最终采收率提供了良好实践。Water appearing in gas wells is a serious problem in the later stage of gas field production,and it greatly reduces the recovery of gas fields. Because the operation cost of water plugging and drainage in gas production is very high in offshore oil and gas fields,so it is the great significance to study the measures of gas production with water. Combining with the actual situation of well A9 in an offshore gas field,by calculating the micro-positive flow rate of stable liquidcarrying production in gas wells and the energy loss of gas-liquid two-phase flow through the valve core of oil nozzle,the corresponding measures for prolonging the service life of water-producing gas wells were taken. Good practice was provided in order to prolong the service life of water wells in offshore gas fields and improving the ultimate recovery.
