Aspects of the present invention provide a tubular handling system for handling wellbore tubulars. In one aspect, the present invention provides a tubular handling system adapted to retain a tubular without damaging the outer surface of the tubular. In another aspect, the present invention provides a method of connecting tubulars by remotely controlling the connection process, including joint compensation, alignment, make up, and interlock. In one embodiment, the tubular handling system comprises an elevator (50) adapted to support a tubular utilizing a first portion of an upset of the tubular and a spider (70) adapted to support the tubular utilizing a second portion of the upset. In another embodiment, at least one of the elevator and the spider is remotely controllable. In yet another embodiment, the tubular handling system comprising a joint compensator system (200) adapted to provide fluid communication to the elevator during rotation of the tubular.

Des aspects de la présente invention concernent un système de manipulation de matériel tubulaire pour puits de forage. Dans un aspect, cette invention a trait à un système de manipulation de matériel tubulaire conçu pour retenir du matériel tubulaire sans endommager la surface externe dudit matériel. Dans un autre aspect, ladite invention a pour objet un procédé de raccordement de matériel tubulaire par télécommande du processus de raccordement, notamment, la compensation, l'alignement, la constitution et le verrouillage de joints. Dans un mode de réalisation, le système de manipulation du matériel tubulaire comporte un ascenseur élaboré pour soutenir le matériel tubulaire utilisant une première partie d'une extrémité refoulée dudit matériel et une araignée conçue pour soutenir le matériel tubulaire au moyen d'une seconde partie de l'extrémité refoulée. Dans un autre mode de réalisation, l'ascenseur ou l'araignée peut être télécommandé. Dans un mode de réalisation différent, le système de manipulation de matériel tubulaire comprend un système compensateur de joints élaboré pour engendrer une communication fluidique jusqu'à l'ascenseur pendant la rotation dudit matériel.
