摘　　要：中-高含凝析油凝析气藏A,多口气井因严重积液无法生产。为了保证产气,排出井筒积液,对排液采气工艺进行了研究,并优选出适合A气田的排液采气工艺。通过现场应用,连续油管注氮气排液采气取得了较好的效果,对于中-高含凝析油凝析气藏排液采气具有较好的借鉴意义。In condensate gas reservoir A which include medium-high condensate oil,several gas wells unable to produce due to the serious wellbore liquid.In order to ensure gas production and discharge wellbore fluid,the drainage gas production process was studied,and the drainage gas production process suitable for A gas field was optimized.Through field application,nitrogen injection and drainage of coiled tubing for gas recovery has achieved a good effect,which has a good reference significance for gas recovery of condensate gas reservoir included medium-high condensate oil.
