Abstract

L'outil permet d'attaquer la carotte en formation sans risque de bourrage des conduits d'évacuation de la boue en raison de l'éclatement de la carotte. A cet effet, l'outil comporte sur son axe 7 un cône d'attaque 4 porteur d'un diamant pivot 5 s'appuyant sur la carotte 3. La décompression de la région 16 facilite la désagrégation en petits éclats qui s'évacuent à la périphérie avec la boue 8. L'invention s'applique au forage de tous terrains.
