FIELD: oil and gas industry.
SUBSTANCE: invention relates to packers used during well operations, in particular to reinforcement of sealing glands of inflatable packers operating in a cased well with sliding. In the method of reinforcing the sealing gland of an inflatable packer sliding along the cased wall of a well, with a plurality of reinforcing plates located between the chamber and the sliding gland, the plates are made with clamps at the ends, ensuring a constant length of the plates with a given radius of inflation of the plates, holding a given pressing force of the sliding gland against well wall, regardless of the pressure in the chamber. Many reinforcing plates are assembled into one part, made with slots on a flexible sheet wound on a packer in a multi-layer roll.
EFFECT: achievement of the specified inflation diameter.
