Abstract

Cette invention concerne un système d'actionnement d'un outil de fond de puits, lequel système comprend un aimant se composant d'un aimant attractif (12) et d'un aimant répulsif (13). Sous l'effet d'une pression hydraulique, cet aimant peut passer d'une position active, durant laquelle il entraîne le fonctionnement d'un déclencheur, d'un clapet (8) ou d'un ressort, à une position non active durant laquelle l'outil n'est pas actionné. Ce système d'actionnement fait appel à la pression hydraulique sans pour autant nécessiter la présence d'orifices hydrauliques dans le revêtement ou le mandrin.
