Abstract

Cette invention porte sur un système de forage et sur un procédé de forage d'un puits de forage dans une formation terrestre. Ce système comprend : une unité de forage servant à forer un puits de forage ; une unité de pompage servant à pomper le fluide de forage dans le puits de forage pendant le forage ; et un système d'évacuation du fluide de forage servant à récupérer le fluide de forage du puits de forage, lequel système d'évacuation de fluide de forage comprend une duse servant à duser le débit de retour du fluide de forage ainsi qu'une unité d'alternance servant à alterner le sens d'écoulement dans la duse.
