The invention relates to building and operating vertical, slant directional and horizontal holes of oil and gas fields with difficult operating conditions and can be used for process casing pipes. The inventive tight threaded joint for oil field pipes comprises male and female pipes with a conical thread and stop and sealing surfaces. The stop surfaces are brought into contact by the end surface of the male pipe and the mating end surface of the female pipe. The conical thread configuration has a negative angle along a bearing face. The height of thread of the male pipe is less than the height of thread of the female pipe. The end surfaces are designed so as the area thereof is equal to or greater than 60% of the pipe body. The invention makes it possible to increase the operational reliability and effectiveness of the tight joint and to minimise ecological risks.

L'invention concerne le domaine de formation et d'exploitation de puits verticaux, inclinés ou horizontaux dans des gisements pétroliers ou gaziers, exploités dans des conditions difficiles, et peut s'utiliser dans des tubages à usage technique. Le raccord étanche pour tubes d'extraction de pétrole comprend des tubes extérieurs et intérieur à filetage conique et des surfaces d'appui et d'étanchéité. Les surfaces d'appui sont en contact entre elles par leur surface d'extrémité située sur le tube intérieur et la surface d'extrémité correspondante sur le tube extérieur. Le profil du filetage conique possède un angle d'inclinaison négatif suivant le bord d'appui. La hauteur du profil du filetage du tuyau intérieur est inférieure à celle du profile de filetage du tuyau extérieur. Les surfaces d'extrémité sont agrandies de manière à ce que leur surface occupe au moins 60% du corps du tuyau. L'invention permet d'augmenter la fiabilité à l'usage et l'efficacité du raccord étanche ainsi que de réduire au minimum les risques pour l'environnement.
