Abstract

L'invention concerne un stabilisateur (10) comprenant un corps (12) pourvu d'un alésage traversant (16). Un mandrin (14) comprenant également un alésage traversant (20) peut coulisser axialement dans l'alésage du corps de manière à activer et désactiver un outil de forage. Un étage (64) de ce corps définit des chambres annulaires (102, 104) situées entre le mandrin et le corps sur chaque côté dudit étage. Un piston de commande (18) logé dans le mandrin dirige de manière alternée la boue de forage aspirée sous pression le long de l'alésage du corps et de l'alésage du mandrin vers les chambres de façon à entraîner ledit mandrin par voie hydraulique, d'où l'activation et la désactivation de l'outil. Ce piston de commande comporte un alésage traversant (46) et peut coulisser dans l'alésage du mandrin dans le sens opposé à la force exercée par un ressort de rappel (40) entre une position de pression faible et une position de pression sous l'effet de la pression de la boue de forage. La position de pression correspond en alternance à une position d'activation (a) et à une position de désactivation (b) espacée axialement de la position d'activation sur l'alésage du mandrin.
