An internally rotating nozzle for facilitating drilling through a subterranean formation is rotatably mounted internally within a housing connected to a hose for receiving high pressure fluid. The rotor includes at least two tangential jets oriented off of center for ejecting fluid to generate torque and rotate the rotor and cut a substantially cylindrical tunnel in the subterranean formation.
L'invention porte sur une buse tournante intérieure facilitant le forage dans une formation souterraine et comportant une chambre reliée à un tuyau l'alimentant en fluide à haute pression. Le rotor est muni d'au moins deux buses tangentielles produisant un couple entraînant le rotor et permettant de forer un passage sensiblement cylindrique à l'intérieur de la formation.
