Title (EN) MUD HAMMER
(FR) MARTEAU À BOUE
Abstract:
(EN) A mud hammer is driven by the flow of drilling fluid to generate pressure pulses. Timing and/or amplitude of the pulses are altered to encode data by applying electromagnetic forces to a movable member of the mud hammer. In an example embodiment the movable member carries one or more magnets and electromagnetic forces are applied to the movable member by one or more electromagnets. The mud hammer may also generate electrical power that may be applied to charge batteries and/or drive downhole electrical apparatus.
(FR) L'invention concerne un marteau à boue entraîné par le flux d'un fluide de forage pour générer des impulsions de pression. La chronologie et/ou l'amplitude des impulsions sont modifiées pour encoder des données en appliquant des forces électromagnétiques à un organe mobile du marteau à boue. Dans un mode de réalisation donné à titre d'exemple, l'organe mobile porte un ou plusieurs aimants et des forces électromagnétiques sont appliquées à l'organe mobile par un ou plusieurs électroaimants. Le marteau à boue peut également générer de l'électricité qui peut être appliquée pour charger des batteries et/ou entraîner un appareil électrique en fond de puits.
