A threaded connection (30) with a double abutment shoulder comprises a first tubular component made up onto a second tubular component, said tubular components being intended for exploration or operating a hydrocarbon well, ⋅ the first tubular component (C1) comprising an external abutment (BE), a male threaded connection portion (PC1) extended by a non-threaded terminal portion (PT1) defining an internal abutment (BI) at its axial end; ⋅ the second tubular component (C2) comprising a female end defining at a free end a bearing surface (SA) forced against the external abutment, a female threaded connection portion (PC2) made up with the male threaded connection portion and terminating in an internal shoulder (EI) forced against the internal abutment, an initial non-threaded portion (PT2) connecting the female threaded connection portion to the internal shoulder, which comprises a maximum radial interference locally forming a sealing surface located between the male threaded connection portion and the internal abutment, this maximum interference being located at a non-zero distance from the internal abutment, this distance being at least more than half of an axial distance (d1) of the terminal portion. |
