摘　　要：考虑到渤海油田开发生产不断推进,低产、停产以及报废井越来越多,迫切需要通过钻调整井或治理低效井来挖潜老油田剩余油,提高油田采收率。分析渤海油田不同类型的剩余油分布,研究对应的侧钻方式,根据陆地油田老井侧钻技术调研情况,结合渤海油田自身特点,提出用修井机进行低效井侧钻中短半径井眼的技术思路,配套钻完井工程方案及作业成本初步估算,认为技术方案可行。Considering of the development of Bohai reservoir carrying forward,there are more and more low-production wells,closed wells and abandoned wells,which drives to tap the latent oil remaining through drilling adjustment well or administering inefficient well in order to improve the field recovery ratio. The sidetracking technology is researched by analyzing different type of remaining oil distribution in Bohai oilfield. According to the survey case of side tracking of land field old well,the authors provide a technique clue and assorted wells engineering scheme that drilling sidetracking inefficient well in middle-short radius wellbore with service rig,and estimate the initial activity costs. The approach is proved to be available that drilling sidetracking inefficient well in middle-short radius wellbore with service rig.
