Abstract
(EN)
Apparatus for boring in a bore hole, comprises: one or more conveying means (20a, 20b, 26, 16, 15a, 15b); for the or each conveying means, a plurality of cutting means (24). The or each conveying means is arranged to move the respective plurality of cutting means in turn to an end (18a) of the conveying means at which to impact a cutting face of a bore hole and away from the end, thereby to deepen the hole.
(FR)
La présente invention concerne un appareil de forage dans un puits de forage, comprenant : un ou plusieurs moyens de transport (20a, 20b, 26, 16, 15a, 15b) ; pour le moyen ou pour chaque moyen de transport, une pluralité de moyens de coupe (24). Le moyen ou chaque moyen de transport est agencé pour déplacer tour à tour la pluralité respective de moyens de coupe vers une extrémité (18a) du moyen de transport au niveau duquel une face de coupe d'un puits de forage est heurtée, à l'opposé de l'extrémité, ce qui permet d'approfondir le trou.
