Abstract

Procédé et appareil de découpage d'un tube rigide suivant un plan perpen iculaire à son axe. Deux charges explosives 30 et 32 sont disposées en regard de manière à se trouver sur l'axe longitudinal du tube et de manière que leurs extrémités rapprochées soient en contact et délimitent un espace formant une séparation entre la partie restante de l'une des charges et les parties restantes de l'autre charge, et des déformateurs situés aux extrémités éloignées desdites charges sont destinés à amorcer simultanément ces charges à ces extrémités éloignées. Application au sectionnement des colliers des tiges de forage dans le puits.
