Abstract

Dans un trépan rotatif pour forages profonds, constitué d'un corps de trépan avec une queue de jonction assurant la liaison avec un train de tiges de forage, cette tete comporte une zone périphérique parallèle à son axe longitudinal central et une zone d'about faisant saillie dans le sens du forage qui est pour partie en forme de cone dont l'axe est décalé parallèlement à l'axe central longitudinal de la tete, l'axe longitudinal de la queue de jonction coincidant avec l'axe du cone.
