Abstract

Et første sett anordninger er anordnet for å overføre data fra et sted i en foret seksjon av en brønn (1, 3) til et fjernt sted. En anordning kan utnyttes som en reléstasjon (6) for å øke den operasjonelle dybde. Signaler tilføres og mottas fra strengen (1) ved reléstasjonen (6) og en valgt lengde av strengen er utstyrt med isolerende avstandsutstyr (9) på begge sider av reléstasjonen for å sikre at strekningen og foringen (3) blir effektivt isolert over en valgt minste distanse. Dette gjør det mulig for spenningsforskjeller å både bli påført og påvist fra strengen, for derved å muliggjøre sending og mottagning av data. Et andre sett anordninger (fig. 8) er anordnet for å sende fra en intern enhet (408) innenfor en foret seksjon av brønnen (401, 403) til det umiddelbart omgivende område utenfor foringen (403). Den interne enhet (408) fører strøm inn i strengen (401). En toroid (415) som omgir foringen (403) er anordnet for å fange opp signaler. Forbindelser som befinner seg i avstand fra hverandre mellom strengen (401) og foringen (403) er utstyrt med ledende pakninger (411). Et manglende samsvar mellom strømmen som flyter i strengen (401) og foringen (403) genereres slik at en fluks forskjellig fra null sees av ringen, og et signal således kan mottas.
