Title (EN) DOWNHOLE TOOLS WITH POWER UTILIZATION APPARATUS DURING FLOW-OFF STATE
(FR) OUTILS DE FOND DE TROU AVEC APPAREIL UTILISANT DE L'ÉNERGIE EN ÉTAT D'ÉCOULEMENT
Abstract:
(EN) A drilling assembly for use in drilling of a wellbore is disclosed that in one non-limiting embodiment includes a device that detects a flow-off state, a power generator that generates electrical energy in response to a fluid flowing through the drilling assembly during the flow-off state, and a circuit that utilizes such power to perform one or more selected operations in response to the detection of the flow-off state, including, but not limited to, storing data in a memory; shutting certain devices in the drilling assembly and parking a device in a desired position.
(FR) Cette invention concerne un ensemble de forage destiné à être utilisé lors du forage d'un puits de forage, qui, dans un mode de réalisation non limitatif, comprend un dispositif qui détecte un état d'écoulement, un générateur d'énergie qui génère de l'énergie électrique en réponse à un fluide s'écoulant à travers l'ensemble de forage pendant l'état d'écoulement, et un circuit qui utilise cette énergie pour effectuer une ou plusieurs opérations sélectionnées en réponse à la détection de l'état d'écoulement, y compris, mais pas exclusivement : le stockage de données dans une mémoire ; la fermeture de certains dispositifs dans l'ensemble de forage ; et le stationnement d'un dispositif dans une position désirée.
