Abstract

En perforeringskanon-enhet innbefatter et langstrakt legeme (20) som bærer en kapasltiv utladnings-av- fyrlngsenhet (25) l form av en langstrakt sylinder som avslutter l den nedre ende med en gjennomføring (28). Gjennomføringen (28), beskyttet av en elastisk muffe (37), står i forbindelse med en svært kort koaksial- kabel (40) lagret i et kammer (32). I bunnen av kammeret (32) står koaksialkabelen (40) i forbindelse med et detonatorhode (55). Det er en langstrakt, sylindrisk konstruksjon. Det omslutter og rommer på beskyttende måte enden av en detoneringsstreng (52). På innsiden bærer det en elektrisk pulsinitiert flyvesklve detonatormekanisme. Konstruksjonen er konstruert til å undertrykke induktans i avfyringskretsen fra den kapasitive avfyringsenhet slik at korrekt stigningstid og strømstyrke l avfyringspulsen kan oppnås.A perforating gun assembly includes an elongate body (20) carrying a capacitive discharge firing unit (25) in the form of an elongated cylinder terminating at the lower end with a passageway (28). The bushing (28), protected by an elastic sleeve (37), communicates with a very short coaxial cable (40) stored in a chamber (32). At the bottom of the chamber (32), the coaxial cable (40) communicates with a detonator head (55). It is an elongated, cylindrical construction. It protectively encloses and accommodates the end of a detonation strand (52). Inside, it carries an electric pulse-initiated flywheel detonator mechanism. The structure is designed to suppress inductance in the firing circuit from the capacitive firing unit so that the correct rise time and current in the firing pulse can be obtained.
