FIELD: oil industry.
SUBSTANCE: invention relates to oil industry and may be used for isolation and isolation of borehole intervals. Swellable packer comprises a body, thrust ring and sealing element of water-swellable polymer. Thrust rings on side opposite sealing element, are equipped with collet latches to reduction of pressure rings, on other side stop rings are provided with groove near body. Thrust rings are made of steel, which is stronger than material of steel body. On top and bottom of thrust rings are arranged on body centralisers-turbulators.
