Abstract

L'invention concerne un appareil d'étanchéification haute pression et un procédé associé. L'étanchéification permet d'isoler un câble métallique entrant dans une tête de forage à mécanisme d'entraînement supérieur par l'intermédiaire d'un système d'accès à entrée par le haut en vue d'une réduction de la fuite et de l'échappement de liquides du train de tiges dans l'atmosphère. Un compartiment d'extension comprenant un ensemble tube d'écoulement peut éventuellement être utilisé pour réaliser cette opération. L'ensemble tube d'écoulement permet un abaissement de la pression le long du conduit pour câble métallique le traversant, d'où une réduction du risque d'échappement de liquides.
