Abstract

Den foreliggende oppfinnelse tilveiebringer generelt et nedihullsverktøy med et forbedret middel for overføring av data til og fra et verktøy ved bruk av rør med ledning som er i stand til å overføre et signal og/eller kraft mellom brønnens overflate og en hvilken som helst komponent i en borestreng. Ved ett aspekt innbefatter et nedihullsverktøy et legeme og en spindel (110) som er plassert i legemet, og hvor spindelen er bevegelige med hensyn til legemet. En ledningsforbindelse (135) løper over hele lengden av legemet og tillater signaler og/eller kraft i å overføres gjennom legemet mens verktøyet skifter lengde.
