FIELD: gas and oil production.
SUBSTANCE: procedure for perforating operations in well consists in transportation of cumulative perforator on cable into required interval of well, in its orientation, in successive actuation of cumulative charges of perforator and in formation of channels oriented in required position for fluid inflow in casing and rock. A gravitational orientator with set off gravity centre is connected to the perforator before transportation into a required interval to facilitate a required position in the well. Position of the gravitation orientator relative to the perforator and charges is fixed. Orientation of the perforator in the well before its actuation is performed by means of the gravitational orientator and a cable.
EFFECT: raised efficiency of facilitation of required position of perforator in well, reduced time and expenditures for its orientation.
