Abstract
La présente invention concerne des ensembles tubes de surforage utilisés dans les puits de forage; elle comprend un ensemble tube de surforage (2) muni d'une couronne de surforage (10) fixée à un tube de surforage (18), et un dispositif stabilisateur (22) de tube de surforage qui est placé sur le tube de surforage (18) de manière à empêcher dans une large mesure la couronne de surforage (10) de s'écarter d'une position désirée lors de l'utilisation. Par rapport aux ensembles de l'état antérieur de la technique, l'ensemble tube de surforage de la présente invention présente l'avantage de constituer un moyen qui permet de maintenir le tube de surforage éloigné de la paroi d'un puits de forage ou du tubage (52) d'un puits de forage et, par conséquent, de réduire la force de torsion nécessaire pour faire tourner la colonne de tubage et de restreindre la tendance de la couronne de surforage (10) à dévier d'un parcours préféré de descente le long du puits de forage.
