Abstract

Oppfinnelsen vedrører en styrbar borkroneanordning (10), spesielt for bruk ved boring av borehull for olje- og gassutvinning. I henhold tU oppfinnelsen er det tilveiebrakt en styrbar borkroneanordning (10) innbefattende en borkrone (12), en styrekomponent (16) og en stabUisator (14), idet styrekomponenten (16) er avpasset for å tilveiebringe en styrekraft som ved bruk kan drive borkronen (12) langs en ikke-lineær bane, idet stabUisatoren (14) er anordnet meUom borkronen (12) og styrekomponenten (16) og ved bruk tilveiebringer et omdreiningspunkt for styrekraften tilveiebrakt av styrekomponenten (16), idet posisjonen til omdreiningspunktet tilveiebrakt av stabilisatoren (14) er justerbar i forhold til borkronen (12) og styrekomponenten (16). Ved bruk kan posisjonen til omdreiningspunktet bli justert for å variere den maksimale krummingen tU borehullet og å passe til fjelltypen(e) som blir boret.
