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.A first set of devices is arranged to transmit data from a location in a lined section of a well (1, 3) to a remote location. A device can be used as a relay station (6) to increase the operational depth. Signals are applied and received from the string (1) at the relay station (6) and a selected length of the string is equipped with insulating spacers (9) on both sides of the relay station to ensure that the stretch and the liner (3) are effectively insulated over a selected minimum. distance. This makes it possible for voltage differences to be both applied and detected from the string, thereby enabling the transmission and reception of data. A second set of devices (Fig. 8) is arranged to transmit from an internal unit (408) within a lined section of the well (401, 403) to the immediate surrounding area outside the casing (403). The internal unit (408) conducts current into the string (401). A toroid (415) surrounding the liner (403) is arranged to pick up signals. Connections spaced between the string (401) and the liner (403) are provided with conductive gaskets (411). A mismatch between the current flowing in the string (401) and the liner (403) is generated so that a flux other than zero is seen by the ring, and a signal can thus be received.
