THREATED CONNECTION FOR DRILLING AND OPERATING HYDROCARBON WELLS

摘要

The invention concerns a set for manufacturing a threaded connection, comprising a first and a second tubular component with an axis of revolution (10), one of their ends (1, 2) being provided with a threaded zone (3; 4) formed on the external or internal peripheral surface of the component depending on whether the threaded end is of the male or female type, said ends (1, 2) finishing in a terminal surface (7, 8), said threaded zones (3; 4) comprising, over at least a portion, threads (32, 42) comprising, viewed in longitudinal section passing through the axis of revolution (10) of the tubular components, a thread crest (35, 45), a thread root (36, 46), a load flank (30; 40) and a stabbing flank (31; 41), the width of the thread crests (35, 45) of each tubular component reducing in the direction of the terminal surface (7; 8) of the tubular component under consideration, while the width of the thread roots (36, 46) increases, the profiles of the load flanks and/or the stabbing flanks of the male and female threaded zones, viewed in longitudinal section passing through the axis of revolution (10) of the tubular components, each having at least one identical portion (E, E') such that the male and female threads can be fitted one into the other over said identical portions (E, E') when the first and second tubular components are made up one into the other, characterized in that the identical portions (E, E') of the male and female ends (1, 2) are radially offset with respect to each other.
