摘要

The proposed utility model relates to oil and gas industry, in particular to the overhaul and repair of wells, namely to devices breakout, dokrepleniya, screwing unscrewing wellhead production string. Device for releasably, dokrepleniya, makeup and breakout wellhead production casing comprises a cylindrical body with a slit tubular telescopic arm, the upper and lower flanges with a slot, the bolts, the upper flange with the slot and a lower flange with a slit formed by a different type of flange wellhead . The device is installed on the flange of the column head, and the torque is transmitted directly to the bolts connecting the bottom flange and the slotted flange wellhead. The estimated utility model ensures the quality and reliability of threaded connections wellhead and production casing, considerably increases the productivity of work, allows an increase or decrease in height of the production tubing without pulling the tubing. The device is simple to manufacture and maintain.
