Abstract

Forage des formations de terrain. Le trépan comporte un corps fixé par un raccord fileté conique 6 à l'extremité inférieure du train de sonde avec des plats pour faciliter le montage et le démontage, et une tête de trépan 2 comportant une queue servant de tourillon, montée dans le corps pour permettre la rotation de la tête 2 qui comporte une face inférieure conique avec des dents en carbure de tungstène 3, la boue de forage étant projetée à travers un ajutage débouchant dans un évidement latéral du corps. Un tel trépan convient pour des forages très divers, par exemple dans du sable, des roches dures ou de l'argiles.Drilling of field formations. The bit has a body attached by a tapered threaded connection 6 to the lower end of the sounding train with flats to facilitate assembly and disassembly, and a bit head 2 with a shank serving as a trunnion, mounted in the body for allow the rotation of the head 2 which has a conical underside with tungsten carbide teeth 3, the drilling mud being projected through a nozzle opening into a lateral recess of the body. Such a bit is suitable for a wide variety of drilling, for example in sand, hard rocks or clay.
