Abstract
La présente invention concerne un outil tranchant descendant (20) servant à découper des matériaux sur place, dans un lieu de forage (22). Il est doté d'une extrémité tranchante (32) conçue pour qu'un fluide à pression élevée se dégage de celle-ci. Ledit outil comprend un bloc moteur (34) à plusieurs étages de pression disposés en série, chacun de ces étages permettant d'augmenter la pression du fluide pour qu'il atteigne un niveau de pression supérieur à celui de l'étage précédent. Le fluide à pression élevée est évacué sous forme de courant jet par l'extrémité tranchante. L'outil comprend également un système de pulsation (35) qui permet de pulser le fluide avant que celui-ci ne soit évacué à travers l'extrémité tranchante. Une unité de commande (36) permet de commander la positon et l'orientation de l'extrémité tranchante par rapport au matériau. Il est possible de programmer l'outil tranchant descendant de façon à ce qu'il découpe les matériaux selon des modèles préalablement définis. Ledit outil tranchant peut être utilisé pur découper des éléments supports de constructions en mer, soit depuis l'intérieur desdits éléments, soit depuis l'extérieur. Dans un mode d'exécution préféré, l'outil tranchant est utilisé pour retirer le matériau terre situé autour des éléments supports encastrés, puis pour trancher les éléments supports au-dessous du fond de la mer. L'outil tranchant peut être utilisé pour découper des tuyaux emboîtés après avoir tiré du forage une longueur sélectionnée de ces tuyaux emboîtés.
