Abstract

Outil de forage (2; 86)) et procédé de sectionnement d'une section de tube (16') d'un train de tiges (16). Cet outil comprend : un mandrin pour tube à écoulement traversant (20; 20a, 20b) raccordé entre un train de travail (6) et un sectionneur de tube (12); de premiers moyens de préhension commandés (36, 44) pouvant être ancrés, via un mouvement régulé relatif du mandrin pour tube (20; 20a) dans une première direction, contre la partie de tube sectionnée (16'), avant et pendant le sectionnement et le retrait du train de tubes (16); de seconds moyens de préhension commandés (56, 64) pouvant être ancrés, via un mouvement régulé relatif du mandrin pour tube (20; 20b) dans une première direction, contre la partie de tube sectionnée (16'), avant et pendant le retrait de cette section (16'); et la section de tube; et un tourillon (30) permettant au mandrin pour tube (20; 20a, 20b) de tourner pendant le sectionnement du train de tiges (16). L'outil de forage (2; 86) comprend entre autres un corps d'étanchéité expansible (32) qui est disposé autour du mandrin pour tube (20; 20a, 20b) et qui est raccordé fonctionnel aux seconds moyens de préhension (56, 64), ce qui déclenche, sur sollicitation de ces seconds moyens (56, 64) une compression et ipso facto une expansion du corps d'étanchéité (32) jusqu'à ce que ce dernier établisse un contact étanche avec la section de tube (16').
