Designed for reliable isolation of annular spaces in the casing string to achieve zonal separation. The packer is installed on the casing column at a specified depth interval during well completion

Helps prevent inter-formational flow and isolates gas, oil, and water-bearing formations

Pressure drop tolerance up to 68.9 MPa

Permissible installation angle from 0 to 95 degrees

Can be manufactured with various types of connection threads, including premium threads from the TMK UP family

Maximum operating temperature up to 110°C

HYDROMECHANICAL CEMENTING PACKER

The packer consists of a body with a sealing element equipped with end protections and a hydraulic pusher, which is secured by shear screws. A step retainer is installed to prevent reverse movement of the hydraulic pusher. All parts of the packer are sealed with rubber O-rings.

SEGMENTING THE LINER INTO ISOLATED INTERVALS
After lowering the liner and flushing the transportation string, a 25 mm ball is dropped and pumped until it seats in the activation coupling. Then, the pressure in the tubing and liner is increased to 28.0+10% MPa, the screws holding the hydraulic pusher shear, and the pusher moves, deforming the sealing element and end protections, sealing the annular space around the packer.
