Zusammenfassung:	FIELD: mining. ^ SUBSTANCE: method includes lowering damper equipped with end packer setting components into well, installing damper against trouble zone, leveling it with pressure and calibrating its internal surface with expander to press it to walls of well. A length feed of the expander is chosen so as to create depressions in form of one or multifilar helix on internal surface of the damper along its whole length. ^ EFFECT: upgraded efficiency, effectiveness and reliability. ^ 1 dwg
