A downhole motor assembly for driving a drill bit. The assembly includes a hydraulic drive section with a stator and a rotor located inside the stator to form a flow path between the stator and the rotor. Fluid flowing through the flow path in response to a pressure differential across the hydraulic drive section creates an operative force to rotate the drill bit. The assembly also includes a regulation mechanism that includes a valve and a fluid flow diversion bore for diverting at least some fluid from the flow path when the pressure differential across the hydraulic drive section is greater than or equal to a transition pressure differential.

Cette invention se rapporte à un ensemble moteur de fond de puits destiné à entraîner un foret. L'ensemble comprend une section entraînement hydraulique doté d'un stator et d'un rotor situé à l'intérieur du stator pour former une voie d'écoulement entre le stator et le rotor. L'écoulement de fluide à travers la voie d'écoulement en réponse à une pression différentielle sur la section entraînement hydraulique crée une force permettant de faire tourner le foret. L'ensemble comprend également un mécanisme de régulation qui comprend une soupape et un alésage de dérivation d'écoulement de fluide servant à dériver au moins une partie du fluide de la voie d'écoulement lorsque la pression différentielle sur la section entraînement hydraulique est égale ou supérieure à une pression différentielle de transition.
