摘　　要：针对大芦湖油田注水井注水压力高、地层堵塞严重等问题,室内筛选出了适合该油藏的多氢缓速酸体系,并通过正交试验确定了酸液体系的配方。岩心流动实验结果表明,研制的主体酸液酸化改造效果显著。In consideration of the problems like high water injection pressure in the water input wells and the severe formation plugging, etc. at Daluhu Oilfield, one multi-hydrogen retarded acid system was developed, and the formulation of this multi-hydrogen retarded acid system was identified through orthogonal testing. According to the results of core flow experiment, the effect of acidification modification by means of this multi-hydrogen retarded acid system is significant.
