Title
(EN) TOP DRIVE SWIVEL APPARATUS AND METHOD
(FR) APPAREIL DE TETE D'INJECTION A MECANISME D'ENTRAINEMENT SUPERIEUR ET PROCEDE CORRESPONDANT
Abstract
(EN)
For use with a top drive power unit (10) supported for connection with a well string (20) in a well bore (14) to selectively impart longitudinal and/or rotational movement to the well string (20), a feeder (31) for supplying a pumpable substance such as cement and the like from an external supply source to the interior of the well string in the well bore without first discharging it through the top drive power unit (10) including a mandrel (40) extending through a sleeve (150) which is sealably and rotatably supported thereon for relative rotation between the sleeve (150) and mandrel (40). The mandrel (40) and sleeve (150) have flow passages (140, 190) for communicating the pumpable substance from an external source to discharge through the sleeve (150) and mandrel (40) and into the interior of the well string below the top drive power unit (10). The unit can include a packing injection system (225, 226) , clamp (600), and novel packing configuration (305).
(FR)
La présente invention concerne un système d'alimentation à utiliser avec une unité d'alimentation à mécanisme d'entraînement supérieur, conçue pour être reliée à un train de forage dans un puits de forage afin de communiquer de manière sélective un mouvement longitudinal et/ou rotationnel au train de forage. Ce système d'alimentation est conçu pour fournir une substance pompable, telle que du ciment ou une substance similaire, provenant d'une source d'alimentation externe, à l'intérieur du train de forage dans le puits de forage, sans avoir à la décharger d'abord à travers l'unité d'alimentation à mécanisme d'entraînement supérieur qui comprend un mandrin s'étendant à travers une gaine soutenue de manière hermétique et rotative sur le mandrin afin de permettre une rotation relative entre la gaine et le mandrin. Le mandrin et la gaine présentent des passages d'écoulement conçus pour transmettre la substance pompable provenant d'une source externe à décharger à travers la gaine et le mandrin et à l'intérieur du train de forage, en-dessous de l'unité d'alimentation à mécanisme d'entraînement supérieur. Ladite unité peut comprendre un système d'injection de garnissage, une pince et une nouvelle configuration de garnissage.
