摘　　要：超短半径水平井在开采近井地带剩余油,增大泄油面积,挖掘老油田潜力方面具有显著效果。但常规完井工具在曲率半径特别小的条件下,无法满足下入及完井作业要求。文章介绍了适用于超短半径水平井的浮式柔性引鞋、柔性盲管、柔性筛管、柔性管外封隔器等配套完井工具,并进行了相关测试,符合现场应用要求。Ultra-short radius horizontal wells have signif icant effects in exploiting the remaining oil near the well and tapping the potential of old oil f ields.However,conventional completion tools cannot meet the requirements of completion operations under the condition of extremely small radius of curvature.This article introduces the supporting completion tools such as floating flexible shoes,flexible blind pipes,flexible screens,and flexible external packers suitable for ultra-short radius horizontal wells.And carried out relevant tests to meet the requirements of on-site application.
