Patent

CA 2584323

An apparatus and method for use in the off-line make-up of drill pipe stands on drilling rigs used in the exploration and production of oil and gas reserves are disclosed. The disclosed invention is a pipe handling system in which a section of the V-door ramp attached to a drilling rig structure pivots to allow one or more joints of drill pipe to be placed in a vertical position. Through use of an off-line roughneck in conjunction with an off-line drill pipe elevator, the joints of drill pipe held in the vertical position via the pivoting pipe handler of the present invention can be connected together, connected to additional joints of drill pipe, and placed in a racking board to be stored until they are subsequently connected to the drill string. The use of the pivoting pipe handler of the present invention allows stands of drill pipe to be "made-up" without the need to interrupt drilling operations and, thus, significantly reduces the amount of time required to drill a borehole.

L'invention concerne un appareil et un procédé utilisés dans la réparation hors ligne de longueurs de tiges de forage d'installations de forage utilisées dans l'exploration et la production de réserves de pétrole et de gaz. L'invention concerne un système de manipulation de tiges de forage dans lequel une section de la rampe de la porte en V fixée à la structure de l'installation de forage pivote de manière à placer un ou plusieurs joints de la tige de forage dans une position verticale. L'utilisation d'un dispositif sondeur hors ligne conjointement à un dispositif de levage de tiges de forage hors ligne permet de connecter ensemble les joints de la tige de forage maintenus en position verticale au moyen du dispositif pivotant de manipulation de tiges de forage de l'invention, connectés à des joint supplémentaires de la tige de forage, et placés dans une plateforme d'accrochage pour y être stockés jusqu'à ce qu'ils soient ensuite connectés au train de de forage. L'utilisation du dispositif pivotant de manipulation de tiges de forage de l'invention permet aux longueurs d'une tige de forage d'être "réparées" sans interruption des opérations de forage, réduisant ainsi significativement le temps nécessaire au forage d'un trou de forage.
