SETTING DEVICE Russian patent published in 2020 - IPC E21B23/06 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to oil and gas industry and can be used for installation of packer and multi-packer layouts in well casing at impossibility to transfer weight of well tubing strings (WTS) to packer or at insufficient weight of tubing string. Mounting device comprises an adapter connected to the upper part of the hydraulic cylinder, in which a shaft with a piston is installed, hydraulic channels made in the shaft, a rod connected to the lower part of the barrel and fixed from axial movement by means of a locking assembly consisting of a holder connected to the lower part of the hydraulic cylinder, and shearing elements connecting the holder and the stock. Barrel is installed in hydraulic cylinder under adapter. In annular space between barrel and hydraulic cylinder on top and bottom - under hydraulic channels - sealing units are installed. Rod is fixed against rotation relative to the hydraulic cylinder by means of a key installed inside the cartridge with possibility of axial movement along the longitudinal groove of the rod.

EFFECT: creation of simple and reliable design of device for installation of mechanical packers by hydraulic method, as well as provision of possibility to transfer torque to below installed equipment.
