摘　　要：双河油田ⅧⅨ油组经历了30多年的开发,目前已进入特高含水开发后期,调整和挖潜的难度增大,单元开发效果持续变差。通过主力油层细分流动单元、分时剩余油研究、强水淹层细分评价等综合挖潜技术,对双河油田ⅧⅨ油组进行综合评价,搞清了单元的剩余油分布特征,并利用补孔、调层、解堵、复产、大修等手段对潜力层进行挖潜。通过一系列综合调整挖潜后,进一步完善了注采关系,提高了单元开发效果。ⅧⅨ in Shuanghe Oilfield has experienced development for more than 30 years.At present,it entered into the late stage of extremely high water-cut recovery,adjustment and the tapping the potential was difficulty,the unit development effect continued to be deteriorated.Through the sub-division of flow units of the main reservoirs,time-remaining oil research,evaluation of water-flooding subdivision,tapping the potential technology,ⅧⅨ Oil Formation in Shuanghe Oilfield was comprehensively evaluated,and the distribution characteristics of remaining oil was sorted out ,reperforation,layer adjusting,blocking removal,complex production,overhaul and other means were used for tapping the potential of remaining oil.After that a series of comprehensive adjustment are further improved,the injection and production relations are improved for development effect.
