双河油田ⅧⅨ油组高含水开发后期剩余油综合挖潜技术

摘要

双河油田ⅦⅨ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.%Ⅷ Ⅸ 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, Ⅷ Ⅸ 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 effecl.
