DEVICE OF FIRING GUN Russian patent published in 2011 - IPC E21B43/117 F42B1/00 

FIELD: machine building.

SUBSTANCE: device consists of tubular case with hollow internal channel, of built in loading tube designed for installation in channel of case and containing receiving reservoir of initiator with radio frequency safety device, of receiving reservoir of electric wiring, of receiving reservoir of cumulative charge and of receiving reservoir of detonating fuse. The initiator with the radio frequency safety device is installed in the corresponding receiving reservoir of the loading tube. Electric wiring is made in the corresponding receiving reservoir of the loading tube and is connected to the initiator with the safety device. The cumulative charge is installed in the corresponding receiving reservoir of the loading tube. The detonation fuse is placed in the corresponding receiving reservoir of the loading tube and it connects the cumulative charge to the initiator with the radio frequency safety device. The initiator with the radio frequency safety device, electric wiring, the cumulative charge and the detonating fuse are installed in a position different from the position of a well.

EFFECT: raised reliability of perforator.
