Abstract
En perforeringskanongruppe for perforering av to eller flere soner omfatter to eller flere kanonsett som utgjøres av kanoner, detonatorer og annet tilhørende utstyr. I en utførelse blir kanonsettene forbundet via tilkoplinger som sender aktiveringssignaler mellom kanonsettene. Avfyringen av et kanonsett frembringer dette overførte kanonaktiveringssignal enten direkte eller indirekte. En anordning initierer et overfiatesignal avfyringen av et første kanonsett, mens etterfølgende avfyringer initiert ved avfyring av kanonsettene som utgjør kanongruppen. En eksempeltilkopling blir minst delvis fylt med et signaltransportmedium som er tilpasset for å overføre aktiveringssignaler mellom kanonsettene. I en utførelse er signaloverføringsmediumet væske. Væsken kan tilsettes tilkoplingen enten på overfiaten eller i borehullet.
