Abstract

En telemetrianordning og en fremgangsmåte for å kommunisere data fra et brønnhullssted gjennom et borehull til overflaten er beskrevet, som innbefatter en lyskilde, en optisk fiber som er plassert langs lengden av brønnhullet og som mottar lys fra lyskilden, en transduser lokalisert for å produsere et kraftfelt (f.eks. et magnetfelt) over den optiske fiberen og dens beskyttende skall, uten mekanisk gjennomtrengning av skallet ved brønnhullsposisjonen, én eller flere sensorer for måling av brønnhullstilstander og/eller parametere, en styringsenhet for å tilveie- 10 bringe et modulert signal til magnetfeltgeneratoren, hvor det modulerte signalet under driftsbetingelser representerer målinger ved hjelp av én eller flere sensorer, og en optisk detektor innrettet for å detektere endringer i lysintensiteten eller polariseringen til det lys som passerer gjennom fiberen.
