Abstract

Anordningen omfatter en sender/mottaker-spole (5) som kan beveges i brønnen og en anordning (8) for å generere et periodisk eksiteringssignal som skaper en overspenning i sender/mottaker-spolen. Variasjonen av spolens overspenningsfaktor blir bestemt ved hjelp av en måleanordning (9) og analysert ved hjelp av en behandlingsanordning (10) for å tilveiebringe informasjon om verdien av konduktiviteten i den formasjon som befinner seg omkring brønnen.The device comprises a transmitter / receiver coil (5) which can be moved in the well and a device (8) to generate a periodic excitation signal which creates an overvoltage in the transmitter / receiver coil. The variation of the coil overvoltage factor is determined by a measuring device (9) and analyzed by a processing device (10) to provide information on the value of conductivity of the formation around the well.
