摘　　要：目前濮城油气田南区沙二上1-3气顶气藏已进入后期开发,气井普遍水淹,严重影响了气井的正常生产。为了解决这一问题,根据不同气井水淹的具体情况,分别对气藏的气井应用了小泵加气锚、泡排、液氮气举、下电泵、酸化等配套工艺技术对气藏进行挖潜,取得了较好的采气效果。1-3 gas reservoir in upper Es2 in southern area of Pucheng oil-gsa fied is in the middle-later development period.The gas wells are characterized by the watered out state.All of these production of the gas wells according to the characters.Five kind of suilable potential excavating technologies were used to solve the problems,they are small pump add gas anchor,foam,liquid nitrogenfor gas lift,submersible electric pump and aciding.After being applied in Pucheng oil-gas field for the laster,these technologies shows good effect on draining liquid for gas recovery.
