摘　　要：姬塬油田YC9储层具有底水发育、埋藏深、物性差、不经改造基本无自然产能的特点,同时对于油层较薄且隔夹层遮挡条件差的底水油藏或与底水直接相连的薄油层储层,压裂改造适应性较差。为此,结合该类储层改造难点,通过技术调研优选了深度酸化改造工艺,研制出了一种缓速性能好,能够深部酸化地层的低伤害酸液体系,并初步形成了适合该类储层的深度酸化改造工艺,现场应用11口井,试验效果良好。The YC9 oil reservoir with bottom water in Jiyuan Oilfield has deep buried depth,which exhibits poor physical properties and yields no natural production without fracturing. Meanwhile,for the thin oil zone and poor stress shadow,the conventional fracturing effect in YC9 oil reservoir is poor. To solve the problem,the depth acidizing technology was preferred according to the YC9 reservoir stimulation difficulties,and an acidizing fluid with low damage was developed,which has goodretarding performance and can acidize deep reservoir. Field application results of the depth acidizing technology in 11 wells showed that the increase production was obvious and the technology was fit for the YC9 reservoir.
