Abstract
L'invention concerne un mécanisme de sécurité et un procédé de forage de fond de puits. Dans un exemple, une tête de déclenchement mécanique comprend un percuteur porté sur un support de percuteur à l'intérieur d'un boîtier. Le percuteur peut être déplacé d'une position rétractée à une position de déclenchement pour frapper un dispositif d'amorçage d'explosif. Un élément de retenue retient le percuteur en position rétractée avec l'élément de sécurité en position armée. Un élément de sécurité est sollicité vers une position de sécurité qui bloque en outre le mouvement du percuteur. L'élément de sécurité peut être déplacé vers une position armée qui débloque le mouvement du percuteur en réponse à une pression d'armement fournie en direction de l'orifice du boîtier. L'élément de retenue libère le percuteur en réponse à une pression de déclenchement fournie au boîtier en plus de la pression de déclenchement.
