摘　　要：针对滨南低渗透油田注水效果不好,欠注严重,高压水射流等增注方法效果不理想的实际情况,开展欠注机理研究,并进行酸化增注体系液的配方优选。矿场9口水井的应用表明,研制出的低伤害高效酸液体系有效率100％,起到了显著的增注与增油效果。In accordance with problems in Binnan low permeability oilfield, such as ineffective water flooding, serious under- injection, and high pressure water jet injection being not effective, this paper studies the mechanism of under - injection, and optimizes the formula of acidizing fluid system. Application in 9 water wells showed that the effective rate of this low - harm acid fluid system was 100% , and the injection and oil production had noticeably increased.
