FIELD: mining.
SUBSTANCE: hydromechanical well perforator includes housing, power assisted mechanisms, cutting tool in the form of rolling disc, which is installed with possibility of being extended from the housing at the action thereon of power assisted mechanism, and the above mechanisms are installed in the housing, and a jet nozzle. Housing is fixed on the flow string by means of movable joint in order to provide rotary movement. Rolling disc is installed at an angle to the perforator axis so that the torque moment transmitted to the housing can be created on it during the movement of the housing in production column, and cut slot in production column along helical line.
EFFECT: improving manufacturability, increasing the efficiency of the perforation process and quality of the formation drilling process.
