摘　　要：通过对环江油田长8注水井欠注原因的分析,提出了深部酸化降压增注的技术思路,开展了酸液体系和酸化工艺研究,现场实施取得了良好的效果,为该区注水井降压增注提供了有效的手段。Through the analysis of the causes about the lack of injection at Chang 8 water injection well of Huanjiang oilfield,the paper puts forward the technological ideas of reducing the pressure and increasing the injection by depth acidization,and studies the acid liquid system and the acidizing technology.This technology has made a good effect in the spot implementation and thus provides the effective means for injection wells of this area to reduce the pressure and stimulate the injection.
