Title (EN) A DRILL DEVICE ASSEMBLY, A DRILL STRING ASSEMBLY HAVING SUCH A DRILL DEVICE ASSEMBLY, AND A BACKHEAD AND A CHECK VALVE ENGAGING MEMBER FOR USE IN A DRILL DEVICE ASSEMBLY
(FR) ENSEMBLE DISPOSITIF DE FORAGE, ENSEMBLE TRAIN DE TIGES COMPRENANT UN TEL ENSEMBLE DISPOSITIF DE FORAGE, ET TÊTE ARRIÈRE ET ÉLÉMENT DE PRISE DE CLAPET DE NON-RETOUR DESTINÉS À ÊTRE UTILISÉS DANS UN ENSEMBLE DISPOSITIF DE FORAGE
Abstract:
(EN) A drill device assembly (1), comprising a drill device (2) having at least one movable component (2a), wherein when in use, a fluid flow is directed past the movable component and said movable component moves with respect to the remaining drill device assembly. An inlet flow route (3) for receiving a fluid flow from a portion of a drill string preceding the drill device assembly and conducting said fluid flow past the at least one movable component, and a discharge flow route (4) for discharging fluid flow from the at least one movable component are provided. At least one capturing element (5a, 5b, 5c) is provided in the inlet flow route for recovering particles from a fluid flow. A drill string assembly, and a backhead of a percussion device and an engaging member of a check valve for use in such a drill device assembly are also concerned.
(FR) L'invention concerne un ensemble dispositif de forage (1), comprenant un dispositif de forage (2) ayant au moins un élément mobile (2a), dans lequel, lors de l'utilisation, un écoulement de fluide est dirigé au-delà de l'élément mobile et ledit élément mobile se déplace par rapport à l'ensemble de dispositif de forage restant. Il est fourni un trajet d'écoulement d'entrée (3) destiné à recevoir un écoulement de fluide à partir d'une partie d'un train de tiges de forage précédant l'ensemble dispositif de forage et à conduire ledit écoulement de fluide au-delà dudit élément mobile, et un trajet d'écoulement d'évacuation (4) pour évacuer un écoulement de fluide dudit élément mobile. Au moins un élément de capture (5a,5b, 5c) est disposé dans le trajet d'écoulement d'entrée pour récupérer des particules à partir d'un écoulement de fluide. L'invention concerne également un ensemble train de tiges de forage et une tête arrière d'un dispositif de percussion et un élément de prise d'un clapet de non-retour destinés à être utilisé dans un tel ensemble dispositif de forage.
