Large-drift-diameter supporting sealer capable of being repeatedly set

The utility model discloses a large-drift-diameter supporting sealer capable of being repeatedly set, which comprises a central pipe, and a righting mechanism, a sealing mechanism, a suspension locking mechanism and a driving mechanism are sleeved outside the central pipe. And the upper end of the central pipe is in threaded connection with the upper joint. The large drift diameter is met, and it is guaranteed that a production pipe column and other process pipe columns can smoothly pass through the clamping and sealing section; the device can be repeatedly used, and can be used for the second time by replacing the shear pin after being fished out; large-tonnage supporting and hanging can be achieved, and long-distance target well section clamping and sealing can be completed. 本实用新型公开了一种大通径可重复座封支撑密封器，包括中心管，所述中心管外套有扶正机构、密封机构、悬挂锁定机构和驱动机构。所述中心管上端与上接头通过螺纹连接。本实用新型满足大通径，保证生产管柱及其它工艺管柱可顺利通过卡封段；可重复使用，捞出后更换剪钉即可进行二次使用；可以大吨位支撑悬挂，可以完成长距离目标井段卡封。
