Abstract

La présente invention porte sur des trépans auto-stabilisés et anti-tourbillonnement (105), sur des ensembles de fond de trou et sur des systèmes pour leur utilisation. Un mode de réalisation de l'invention porte sur un trépan comprenant une cavité intérieure en communication de fluide avec un train de tiges de forage, et une pluralité de plaquettes de calibrage (206a) situées à l'extérieur du trépan. Une ou plusieurs des plaquettes de calibrage comprennent un orifice (212) en communication avec la cavité intérieure. Le trépan est configuré de telle sorte qu'un fluide s'écoule de façon continue à partir de chacun des orifices.
