Title (EN) DOWNHOLE TOOL COUPLING SYSTEM
(FR) SYSTÈME D'ACCOUPLEMENT D'OUTIL DE FOND DE TROU
Abstract:
(EN) A downhole tool coupling system (100), comprising a drive stem (102), a sleeve (104), and a plurality of locking clamps (106). The sleeve is longitudinally movable relative to the drive stem. The locking clamps are at least partially encompassed by the sleeve. The locking clamps are adjustable between an open position and a locked position. The sleeve is oriented relative to the locking clamps to adjust the locking clamps from the open position to the locked position as the sleeve moves longitudinally from an upper position to a lower position. Each locking clamp has an interior recessed region (114) configured to clamp the drive stem to a tool stem (103) when in the locked position.
(FR) L'invention concerne un système d'accouplement d'outil de fond de trou (100) comprenant une tige d'entraînement (102), un manchon (104) et une pluralité d'éléments de serrage bloquants (106). Le manchon est mobile dans la direction longitudinale par rapport à la tige d'entraînement. Les éléments de serrage bloquants sont au moins partiellement couverts par le manchon. Les éléments de serrage bloquants sont réglables entre une position ouverte et une position verrouillée. Le manchon est orienté par rapport aux éléments de serrage bloquants pour ajuster ceux-ci de la position ouverte à la position verrouillée lorsque le manchon se déplace longitudinalement d'une position supérieure à une position inférieure. Chaque élément de serrage bloquant comporte une région intérieure évidée (114) conçue pour fixer par serrage la tige d'entraînement à une tige d'outil (103) lorsqu'elle est en position verrouillée.
