Patent

CA 2503692

A well casing system is disclosed for the handling and make-up of casing (35) on a drilling rig in conjunction with a top drive (5) is disclosed. The system comprises a top drive (5), a casing make-up assembly (45), links (27,32), link tilts (29,40), and transfer (30) and lifting (25) elevators. The operator can remotely manipulate the elevators (25,30) to pick up and position a joint of casing (35) above the casing already secured in the drilling hole. The operator can then engage the gripper head (75) and use the rotational capability of the top drive (5) to remotely couple the two joints of casing together.

La présente invention concerne un système de tubage destiné à la manipulation et au blocage de tubage sur une installation de forage dans le cas d'un entraînement par la table. Le système comprend un entraînement par table, une pince de blocage du tube, des bielles, des tirants de bielle, et des élévateurs de transfert et de remontée. L'opérateur peut télémanipuler les élévateurs pour prendre un manchon de tubage et le fixer au-dessus d'un tubage déjà en place dans le trou foré. L'opérateur peut alors serrer la tête de préhension et utiliser la rotation communiquée par la table pour réunir par couplage à distance les deux manchons de tubage.
