Abstract

The invention relates to a method and a drilling assembly comprising a drill bit (18) and a drill rod (20), said drill rod being intended to drive the drill bit in order to form a drill hole (11) having a cylindrical wall (13). The inventive assembly also comprises means for circulating drilling fluids through the drill rods (20) in a downward flow as far as the drill bit (18), said drilling fluids subsequently flowing along the length of the cylindrical wall (13) in an upward flow. The drilling assembly further comprises a sealed cylindrical sleeve (24) which is mounted around the aforementioned drill rods (20) in order to guide the upward drilling fluids between the cylindrical sleeve (24) and the cylindrical wall (13).
