Patent

CA 2557868

Methods and apparatuses for drilling a borehole are disclosed. An electric motor electrically and mechanically coupled to a wired drill pipe is provided. The electric motor couples to a shaft that rotates when power is supplied to the electric motor. The shaft is couplable to a drill bit. The wired drill pipe transfers electricity to the electric motor from the surface. Operation of the electric motor rotates the shaft. The drill bit wears away earth to form the borehole in the earth.

L'invention concerne des procédés et des appareils destinés à forer un puits. L'invention concerne également un moteur électrique couplé électriquement et mécaniquement à une tige de forage câblée. Ce moteur électrique se couple à un axe qui tourne lorsque la puissance est alimentée dans le moteur électrique. Cet axe peut être couplé à un outil de forage. La tige de forage câblée transfert l'électricité au moteur électrique à partir de la surface. Le fonctionnement du moteur électrique met en rotation l'axe. L'outil de forage use la terre afin de former un puits dans la terre.
