Patent

CA 2390191

An apparatus and method for inserting or removing a string of tubulars (17) from a borehole includes a make up/break out mechanism (20, 114, 124) which is capable of adding a tubular to or removing a tubular from the string and a handling mechanism (12) which feeds a tubular into, or removes a tubular from, the make up/break out mechanism. The make up/break out mechanism is moveable along the direction parallel to the axial direction of the string, such that the string may be substantially continuously inserted into or removed from the borehole.

L'invention concerne un appareil destiné à introduire un train de tiges dans un trou de forage ou à le retirer de celui-ci, qui comporte un mécanisme d'assemblage/de séparation capable d'ajouter une tige au train ou à en retirer un, ainsi qu'un mécanisme de manutention qui achemine une tige au mécanisme d'assemblage/de séparation ou en retire un de ce dernier. Le mécanisme d'assemblage/de séparation peut être déplacé dans une direction parallèle à la direction axiale du train, de façon que ce dernier puisse être introduit sensiblement en continu dans le trou de forage ou retiré de ce dernier.
