摘　　要：八面河油田在开发过程中,含水上升快,产量自然递减加快,部分井水淹严重,为稳油控水,利用氮气的特性,促使油藏压力场重新分布,改变驱油剖面,提高油藏的采收率,实现老区稳产。In view of fast beating water increase, quick natural decrease of output and serious water flooding in some wells in developing Bamianhe Oilfield, we use nitrogen to accelerate redistribution of reservoir pressure fields, to change oil displacement profile and to enhance oil recovery, thus realizing stable productivity in old areas.
