Abstract

Det fremlegges et forbedret verktøy, for eksempel tilpasset for å omfatte i det minste del av en brønnkompletteringssammenstilling eller brønnboringssammenstilling. Oppfinnelsen tilveiebringer et forbedret nedihullsverktøy (eller -innretning) som har et friksjonstall i størrelsesorden ti ganger mindre enn de som er kjent fra kjent teknikk, for eksempel i størrelsesorden 0,100 eller mindre. Følgelig tilveiebringer oppfinnelsen et nedihullsverktøy (10; 10a; 10b; 10c; 10d), hvor i det minste del av nedihullsverktøyet eller innretningen er laget av wolframdisulfid. I en fremlagt utførelse omfatter den i det minste del minst én overflate av nedihullsverktøyet, hvor den minst ene overflate omfatter en lagerflate, for eksempel en radiallagerflate og/eller en aksial allagerflate.
