Abstract

Anordning for å overføre et signal fra dypt nede i et borehull gjennom en streng av rør, fortrinnsvis borerør, hvor anordningen omfatter en signalleder og et rør, karakterisert ved at nevnte signalleder befinner seg grensende til en innside av røret, fortrinnsvis borerørseksjon. En overføringsanordning for å overføre et signal fra dypt nede i et borehull gjennom en streng av rør, fortrinnsvis borerør, hvor anordningen omfatter en elektrisk leder som er anbrakt i et rør, fortrinnsvis borerørseksjon, karakterisert ved at anordningen videre omfatter en forsterker.
