Abstract

En kjerneboresammenstilling med utskiftbare skjærevæskedyser som tillater effektiv justering av totalflyttverrsnittet (TFA), betydelig optimalisering av hydraulisk kraft ved skjærefronten for å bedre penetrasjonshastighet (ROP) og kjernekvalitet. Minst en tetningssammenstilling for å begrense borevæskefiyten samtidig som det tillates innbyrdes rotasjon mellom kjernehode-ID og den nedre skoen er plassert i et ringrom som er definert dem imellom.
