Abstract

Eksplosiv perforeringsanordning (10) for å perforere brønner (1) som har et antall av perforeringstrinn (12, 13) anordnet under hverandre, hvilke trinn hver har flere perforeringsladninger (16). Hvert perforeringstrinn har en adresserbar bryter (14) hvilken kobler detoneringsledingen gjennom i hviletilstanden og isolerer detoneringsledningen (11) i driftstilstanden og kobler detoneringsledningen til en tenningsstyreanordning (15) for vedrørende perforeringstrinn.Explosive perforation device (10) for perforating wells (1) having a plurality of perforation steps (12, 13) arranged one below the other, each stage having multiple perforation charges (16). Each perforation step has an addressable switch (14) which connects the detonation line to the idle state and insulates the detonation line (11) in the operating state and connects the detonation line to an ignition control device (15) for regarding the perforation step.
