Title (EN) TURBO-DRILL
(FR) TREPAN A TURBINE HYDRAULIQUE
Abstract:
(EN) The proposed turbo-drill is intended for drilling deep and very deep oil, gas and test wells under complex mountain geological conditions. The turbo-drill comprises a high-speed shaft (6) carrying the turbines (7), a low-speed shaft (10) carrying the rock-crushing instrument (11), and a torque and rotation speed converter (12) for the shafts (13 and 14) connected to the corresponding shafts (7 and 10) of the turbo-drill. A turbine (22) is mounted on the low-speed shaft (10).
(FR) Le trépan à turbine hydraulique de l'invention est destiné au forage de puits de pétrole, de gaz et de test profonds et très profonds, dans des conditions géologiques montagneuses complexes. Le trépan à turbine hydraulique comprend un arbre très rapide (6) portant les turbines (7), un arbre lent (10) portant l'instrument casse-pierre (11), ainsi qu'un convertisseur (12) de force de torsion et de vitesse de rotation, destiné aux arbres (13 et 14) connectés aux arbres correspondants (7 et 10) du trépan à turbine hydraulique. Une turine (22) est montée sur l'arbre à vitesse lente (10).
