摘要
SZX调剖剂是将油田污水回注处理过程中产生的水处理淤泥作主剂,加入一定量添加剂组成。室内研究从水处理淤泥的物化性能入手,分析添加剂、主剂、水质对SZX调剖剂悬浮性的影响;岩芯试验结果表明,SZX调剖剂对不同渗透率岩芯均具有较强的封堵能力,能调整并联岩芯的产液比。在胜利滨南油田进行了现场试验并获得较好的增油降水效果,同时解决了环境污染问题。
Profile modification agent SZX was composed of sludge produced during waste - water reinjection as main agents and quantitative additives. The physical and chemical properties of sludge were studied in lab experiment. The effects of additives, main agent and water quality on suspension property of profile modification agent SZX were analysized. The core test showed that profile modification agent SZX had super plugging capability to cores with different permeability and could modify the produced water- oil ratio of parallel - core. The field test in Binnan Oilfield found that profile modification agent SZX had good oil - increasing and water- decreasing capability and it was benefit to solve the environmental pollution problems
