摘　　要：修井是一项为恢复油气井正常生产所进行的解除故障、完善井眼条件的工作。它是提高单井产量和采收率,延长生产周期的一项重要措施,也是挖掘老井潜力、发现新层位,扩大勘探成果的重要手段。论述了修井过程中众多的储层损害机理,以及相配套的保护储层技术,为更好的在修井过程中保护油气层起指导作用。Workover is aimed at fault disconnection and well completely penetrating.It is an important measure to enhance oil recovery,prolong production cycle, dig out old well potency, discover new formation and enlarge fruit of exploration.This paper introduced multitudinous reservoir damage mechanism and the matching protection technology in workover. It also gave some significance guidance for reservoir protection.
