Abstract

L'invention concerne un procédé et un dispositif pour réaliser des forages très profonds. On réalise un avant-trou par des techniques classiques, puis l'on y descend, à l'extrémité d'un câble ou d'une chaîne, un outil rotatif 1, muni par exemple de couronnes dentées 3a, 3b; pendant au moins toute la durée de l'opération, on maintient le forage rempli avec au moins une substance qui, en tous les points situés à l'intérieur du forage, reste à l'état liquide, et présente une densité supérieure à la densité moyenne des couches forées, de maniere que les débris et les infiltrations éventuelles remontent naturellement à la surface, que les parois du forage soient maintenues et que la foreuse travaille en milieu fluide. L'invention est applicable notamment aux recherches géologiques et minières, ainsi qu'à la récupération de l'énergie géothermique.
