Abstract

Et borefluidleveringssystem til bruk ved boring av borehull med en borkrone, hvilket system omfatter: en primær strømningskrets som har en forholdsvis høy strømningsmengde for overføring av borefluid til og fra borkronen; en sekundær strømningskrets som har en forholdsvis lav strømningsmengde for overføring av borefluid til og fra den primære strømningskrets; og et borkaksoverføringssystem, så som en hydrosyklon eller et roterende filter, mellom de primære og sekundære strømningskretser, som, i bruk, mottar fluid inneholdende borkaks fra den primære krets, separerer fluidet i en første strøm som inneholder hovedsakelig intet borkaks og en annen strøm inneholdende borkaks, idet den første strøm returneres til den primære strømningskrets og den annen strøm ledes til den sekundære strømningskrets.
