Abstract
Tambour de glissement pour le support sélectif d'un train de tiges suspendu dans un puits de forage; ce tambour peut être monté sur une tête de puits. Le tambour de glissement comporte un passage axial qui est aligné avec le puits de forage, et au moins deux passages radiaux traversant une paroi latérale du tambour de glissement et communiquant avec le passage axial. Au moins deux coins de retenue coulissent dans les passages radiaux respectifs. Des actionneurs déplacent les coins de retenue entre une position rentrée où les mâchoires de glissement dégagent le passage axial du tambour de glissement, et une position allongée où les mâchoires de glissement triangulaires des coins de retenue respectifs sont introduites dans un espace annulaire entre le passage axial du tambour de glissement et le train de tiges.
