Title (EN) SYSTEM AND METHOD FOR DRILL STRING VIBRATION CONTROL
(FR) SYSTÈME ET PROCÉDÉ DE COMMANDE DE VIBRATION DE TRAIN DE TIGES DE FORAGE
Abstract: front page image
(EN) A drilling assembly includes a derrick, a swivel assembly coupled to the derrick, and a drill string coupled to the swivel assembly. The drill string includes a plurality of pipe sections, each having an insert providing a material and/or geometrical discontinuity in the pipe section, the plurality of pipe sections forming periodic cells collectively operative to selectively block propagation of vibrations in the drill string.
(FR) Ensemble de forage, comprenant une tour de forage, un ensemble de tête de sonde couplé à la tour de forage, et un train de tiges de forage couplé à l'ensemble de tête de sonde. Le train de tiges de forage comprend une pluralité de sections de tuyau, chacune de celles-ci présentant un insert qui crée une discontinuité matérielle et/ou géométrique dans la section de tuyau, la pluralité de sections de tuyau formant des cellules périodiques utilisables collectivement pour bloquer de façon sélective la propagation de vibrations dans le train de tiges de forage.
