A fluid cutting head (8) of the type having a plurality of nozzles in a rotatable nozzle assembly (9) for cutting a bore hole in rock, has nozzles being arranged to be supplied with high pressure drilling fluid, forming jets positioned to cut adjacent rock. The nozzles include one or more generally axially facing pilot nozzles (1 and 2) and one or more generally radially facing reaming nozzles (3, 4, 5 and 6), at least the pilot nozzles being characterised by a non-tapering outlet section such that the jet issuing therefrom is of substantially constant cross-section in a zone immediately adjacent the outlet section. The pilot nozzles are located in a leading part (26) of the rotatable nozzle assembly (9), having a minimised diameter, while the reaming nozzles are located in the following part (27) of the rotatable nozzle assembly (9), formed in a step-wise fashion to keep the reaming nozzles close to the rock face.
L'invention concerne une tête de coupe à fluide (8) du type équipé de plusieurs buses dans un ensemble de buses rotatif (9) destiné à découper un trou de forage dans une roche; ladite tête de coupe à fluide est dotée de buses qui sont disposées de manière à être alimentées par un fluide de forage à haute pression, formant des jets positionnés pour découper la roche avoisinante. Les buses comportent une ou plusieurs buses pilotes (1 et 2) se regardant généralement axialement et une ou plusieurs buses d'alésage (3, 4, 5 et 6) se regardant généralement radialement, au moins les buses pilotes se caractérisant par une section sortie non conique de sorte que le jet qui en sort est de section transversale sensiblement constant dans une zone jouxtant immédiatement la section sortie. Les buses pilotes sont situées dans une partie avant (26) de l'ensemble de buses rotatif (9), ayant un diamètre réduit, tandis que les buses d'alésage sont situées dans la partie suivante (27) de l'ensemble de buses rotatif (9), formée graduellement afin de maintenir les buses d'alésage proches de la face rocheuse.
