摘　　要：高压、低渗透靠自然能量开采的凝析气藏 ,井筒积液对气井产能影响较大 ,采用N2 气举排液采气会对产层造成一定的污染 ,且有效期短。应用空心抽油杆代替小油管 ,与气举阀等配合 ,可依靠地层自身能量 ,实现井筒积液的自产自排 ,达到气井的连续生产。Condensated fluid have great effect on the production of high pressure,low permeability condensate field.Drainage gas recovery by using N 2 gas lift can cause gas-bearing reservoir damage and validity is short.Using hollow sucker rod replaces little oil pipe and coordiates with gas life valve,so,relying on gas-bearing reservoir self-energy can realize producing of condensate field and attain continuous production of gas well.
