摘要： The invention relates to building and operating vertical, controlled, directional and horizontal holes of oil and gas fields with difficult operating conditions, and can be used for process casing pipes. The inventive tightly 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 that 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 minimize ecological risks.
