Abstract

Det tilveiebringes en eksplosiv pakke for bruk i seismiske undersøkelser, hvilken omfatter en seismisk ladning og en adresserbar bryter for velging av den seismiske ladning for detonasjon. Et tennsett er driftsmessig koplet til den adresserbare bryter for mottaking av en tennspenning via den adresserbare bryter og for produsering av en aktueringsspenning. Aktueringsspenningen kan f.eks. produseres ved øking av størrelsen av tennspenningen. Aktueringsspenningen tilveiebringes til en detoneringsinnretning, som er en innretning som inneholder sekundære eksplosiver. Eksempler på en detoneringsinnretning inkluderer en eksploderende brotråddetonator, en eksploderende folieinitiator-detonator og en halvlederbro-slapperinnretning. Slike eksplosive pakker kan anordnes i et system for anvendelse ved seismiske undersøkelser, hvilket omfatter en basisenhet for tilveiebringelse av velgingssignaler, tennsignaler og utløsningssignaler og en flerhet av eksplosive pakker som er lokalisert i intervaller med innbyrdes avstand langs jordens overflate.An explosive package is provided for use in seismic surveys, which includes a seismic charge and an addressable switch for selecting the seismic charge for detonation. An ignition kit is operatively connected to the addressable switch for receiving an ignition voltage via the addressable switch and for producing an actuating voltage. The actuation voltage can e.g. produced by increasing the size of the ignition voltage. The actuating voltage is provided to a detonator, which is a device containing secondary explosives. Examples of a detonator include an exploding break wire detonator, an exploding foil initiator detonator, and a semiconductor bridge launcher. Such explosive packages may be provided in a system for use in seismic surveys, which includes a base unit for providing select signals, ignition signals and trigger signals and a plurality of explosive packages located at intervals spaced along the earth's surface.
