FIELD: blasting operations.
SUBSTANCE: group of inventions relates to perforating-explosive operations. Device for perforation of wells includes at least one perforation charge; an initiator, which comprises a ballistic circuit adapted for ignition of at least one perforation charge, herewith the ballistic circuit comprises a detonator and a detonating cord; and a ballistic shut-off gate located between the detonator and the detonating cord, herewith the ballistic shut-off gate prevents ignition of the detonating cord, and the ballistic shut-off gate can be removed from the position between the detonator and the detonating cord when a command comes from the surface.
EFFECT: provided is prevention of premature detonation of a borehole perforator, while simultaneously reduced is the volume of operations with electric wiring performed on the surface.
