FIELD: mining.
SUBSTANCE: invention relates to separation individual sections of the well shaft. Device for separation of individual sections of the well shaft includes tubing joints, a sealing element of cylindrical shape installed concentrically to the tubing joint between it and the casing pipe. Sealing element is made of circular sealing elements, between which there are pressure rings made from a material with shape memory. Circular sealing elements are made of basalt fibre having a diameter from 0.5 to 3.5 mcm. Basalt fibre is saturated with metal particles, herewith the metal used for saturation is aluminium powder. At the end of the lower tubing joint there is a support nozzle-coupling made of tungsten carbide, and the circular sealing elements are installed on both sides of the thrust ring.
EFFECT: technical result is the possibility of the device effective operation at high working pressure and temperature.
