Abstract

Cette invention un joint fileté et à un élément mâle de forage par percussion. Ce joint fileté comporte au moins un filetage extérieur généralement cylindrique (14) et un filetage intérieur généralement cylindrique (15). Le filetage extérieur (14), se trouve sur un goujon (12), conçu pour constituer une partie intégrante d'un premier élément de train de forage (10A, 10B). Les filetages possèdent des extrémités de filet (21-24) reliées à des filetages associés à profil droit. Ces filetages (14, 15) possèdent des zones terminales, la section longitudinale de chacun des filetages étant d'un diamètre (R) très restreint. Le filetage extérieur généralement cylindrique (14) est d'une première longueur axiale (L1) et le filetage intérieur généralement cylindrique (15) est d'une seconde longueur axiale (L2), la première longueur axiale (1) étant inférieure à la seconde (L2), de sorte que les deux zones terminales (23, 24)du filetage intérieur cylindrique (15) n'entrent pas en contact avec le filetage extérieur cylindrique (14).
