Title (EN) DRILLING MOTOR WITH BYPASS AND METHOD
(FR) MOTEUR DE FORAGE DOTÉ D'UNE DÉRIVATION ET PROCÉDÉ
Abstract:
(EN) A downhole drilling motor includes a motor housing having an inner bore and an outer surface. A power section includes a stator elastomer at least partially disposed within the inner bore of the motor housing. A bearing section includes an upper bearing at least partially disposed within the inner bore of the motor housing. The motor housing further includes an opening extending from the inner bore to the outer surface to provide a bypass fluid path for a fluid in the inner bore. The opening is disposed on the motor housing between a lower end of the stator elastomer and an upper end of the upper bearing. The bypass fluid path allows the downhole drilling motor to accommodate a higher flow rate of a fluid through the stator elastomer of the power section than through the upper bearing of the bearing section.
(FR) L'invention concerne un moteur de forage de fond de trou comprenant un carter de moteur ayant un alésage interne et une surface externe. Une section d'alimentation comprend un élastomère de stator au moins partiellement disposé à l'intérieur de l'alésage interne du carter de moteur. Une section de palier comprend un palier supérieur disposé au moins partiellement à l'intérieur de l'alésage interne du carter de moteur. Le carter de moteur comprend en outre une ouverture s'étendant de l'alésage interne à la surface externe afin de fournir un trajet de fluide de dérivation pour un fluide dans l'alésage interne. L'ouverture est disposée sur le carter de moteur entre une extrémité inférieure de l'élastomère de stator et une extrémité supérieure du palier supérieur. Le trajet de fluide de dérivation permet au moteur de forage de fond de trou de recevoir un débit plus élevé d'un fluide à travers l'élastomère de stator de la section de puissance que par le palier supérieur de la section de palier.
