摘　　要：华北油田北部砂岩油藏经过长期以来的注水开发,普遍进入中高含水期,综合含水率达到77%以上。油井控水增油难度逐年加大,措施效果也面临逐渐变差的风险,特别是近年来大斜度油井强水淹层机械卡封成功率低,传统挤水泥堵水因水泥抗剪切能力较差导致失败率高。因此,研究更为适合于各类高含水油井的复合堵水方法,优选改进堵水工艺,进行层内挖潜,对于控制油田含水上升,提高单井产量具有十分重要的意义。通过优选配方,在泉28、安56、等断块的高含水潜力井现场应用,效果显著。Sandstone reservoirs in northern Huabei Oilfield have been developed for a long time,and they have entered the middle and high water cut stage,and the comprehensive water content has reached more than 77%. Oil well water control and oil increase difficulty increased year by year,the effect of measures also face the risk of getting poor,especially in recent years the deviated wells of water flooding layer mechanical sealing success rate is low,the traditional cement squeeze water plugging caused by cement shear ability high failure rate. Therefore,it is very important to study the composite water plugging method which is more suitable for various types of high water cut wells,optimize the water plugging technology,and tap the potential within the layer,which can control the water cut rising and improve the production of single well. Through optimizing the formula,it has been applied in the high water cut potential wells of Quan 28,An 56 and other fault blocks,the effect is remarkable.
