System for coupling two tubular ends for use in a well bore, the system comprising a first tubular end (4), a second tubular end (1) for inserting into the first tubular end in axial alignment thereof, thereby forming an annular space (31) between the first tubular end and the second tubular end, and a connecting assembly (16) for axially coupling the first tubular end with the second tubular end whereby the connecting assembly at least partly reaches in the annular space.
L'invention concerne un système permettant de coupler deux extrémités tubulaires que l'on utilise dans un trou de forage et comprenant une première extrémité tubulaire, une seconde extrémité tubulaire à insérer dans la première extrémité tubulaire dans son alignement axial, ce qui permet d'obtenir un espace annulaire entre la première extrémité tubulaire et la seconde extrémité tubulaire, et un ensemble raccord destiné au couplage axial de la première extrémité tubulaire avec la seconde extrémité tubulaire, ledit ensemble pénétrant au moins partiellement dans l'espace annulaire.
