Abstract

L'invention concerne une tige de forage pour machine de forage. Le diamètre extérieur de la tige est un diamètre de grande dimension presqu'égal au diamètre du trou de forage. Un filetage mâle est formé à une extrémité et un filetage femelle est formé à l'autre extrémité, avec au moins une partie de faible diamètre adjacente au filetage mâle. Ladite tige tubulaire à étages peut réduire la flexion des trous. De plus, une machine de forage utilisant ladite tige tubulaire à étages facilite le positionnement de la tige de forage et peut effectuer de manière efficace et sûre l'opération de connexion et de récupération.
