Abstract

L'invention concerne les équipements de forage. Le trépan faisant l'objet de l'invention est du type comprenant des bras portant des molettes 3 dont les projections des axes de rotation sur un plan perpendiculaire à l'axe du trépan forment un certain angle entre elles, et une tubulure 13 amenant le liquide de circulation au front de taille du puits, et est caractérisé en ce que ladite tubulure est montée entre les bras de deux des molettes 3, lesquelles sont disposées de telle façon que les projections de leurs axes de rotation sur un plan perpendiculaire à l'axe du trépan forment un angle plus grand que 120 degrés , mais plus petit que 170 degrés , l'orifice de sortie de ladite tubulure se trouvant entre lesdites molettes. L'invention s'applique notamment au forage des puits de pétrole et de gaz.
