FIELD: oil and gas industry.SUBSTANCE: method for well perforation, the implementation of which provides a communication unit, a chain of gun perforators and a controller related to each gun perforator in the chain; the communication unit, the chain of gun perforators and controllers are mounted in the well; a wireless connection is established between the at least one controller and communication unit along the channel, with bypassing at least one of the other controllers and other device coupled with at least one of the other controllers; that is followed by selective detonation at least of one gun perforators by detonation signal transmission to the controller related to the above, at least one gun perforator.EFFECT: enabled selective initiation of a separate perforator, or a group of one or more perforators within the chain, or avoided early detonation of the chain.31 cl, 5 dwg |
