Abstract

En seismisk kilde for bruk i et borehull (10) omfatter et resonanssystem (26) som blir eksitert ved sin resonansfrekvens mens resonansfrekvensen blir bragt til å variere på styrt måte, for derved å utføre et frekvenssveip. For dette formål blir trykket inne i det rommet (12) som inneholder reaksjonsmassen (30) for resonanssystemet (26), hevet til et gitt, innledende statisk trykk ved hjelp av en høytrykksenhet (60), hvoretter trykket inne i det øvre kammeret (38) i rommet (32) blir bragt til å variere ifølge en hovedsakelig sinusformet lov, ved hjelp av en elektrisk styrt ventil (52) som mates fra en lavtrykksenhet (46), mens det statiske trykk blir bragt til å variere jevnt via en innsnevring (74).
