摘　　要：牙哈气田是采用高压循环注气部分保压开发的大型凝析气田,投入开发以来,取得了较好的开发效果。目前该气藏出现了部分井气窜严重、生产气油比上升加快、凝析油产量递减加剧等问题。应用MDT组合测试,发现牙哈气藏回注干气的运移规律,识别出地下流体纵向分布特征,从而明确了凝析气富集区,为该凝析气藏开发调整提供了依据。Yaha gas field is a large gas condensate field with high pressure cycling gas injection development to partly maintain formation pressure. Since the gas reservoir was put into production, positive development effect has been achieved, but at present, the gas reservoir is confronted with such problems as serious gas breakthrough in some of the production wells, rapid growth of GOR and sharp decline of con- densate oil production rate. By combined testing of MDT （modular formation dynamics tester）, the migration laws of recycled dry gas ware discovered, and the longitudinal distribution feature of subsurface fluid was precisely identified. So the condensate gas concentration zone was confirmed, providing the bases for adjustment of developing the gas condensate reservoir.
