According to the statistics, the accumulative damage well of 600 holes has been discovered, and the damaged well is more than 300, and the damage well is increased by 50 to 60 per year. As at a later stage of oilfield development, facing the plate in order to improve the single well production and ultimate recovery, repair of casing damage Wells is more and more important, while hanging small casing repair set of technology as an important way to repair casing damage Wells become more and more attention and use of. In nearly three years of casing damage Wells, in the treatment of the suspension bushing in the repairing technology in oilfield has been great progress, the technology has gradually become my company is one of the main means of casing damage Wells governance. Hang small repair set of technology is mainly used in the casing pipe leakage, corrosion was badly damaged and long casing damage and point, high pressure water injection must reinforce the wellbore, and the original production horizon for perforating, conventional methods cannot adjust layer casing damage situation, such as in the casing damage repair process has higher application value.
