THREADED TUBULAR CONNECTION TO A TUBULAR COLUMN THAT IS SUBJECT TO DYNAMIC BENDING LOADS

摘要

threaded tubular connection that is resistant to bending stresses. The present invention relates to a threaded tubular connection comprising a male tubular member provided with a male threaded portion and a female tubular threaded portion provided with a female threaded portion which cooperates by bolting with the housing. threaded part, male. According to the invention, the threaded connection comprises at least one transfer zone that can transfer the arm loads between such elements and which is axially spaced from such threaded parts, wherein the male and female members have undulating surface elements and which is axially spaced from such threaded portions, wherein the male and female members have a corrugated surface and a flat surface facing each other, the corrugated surface (5) defining a series of annular, rounded edges (7) which come into contact with each other. contact with the flat surface with a radial interference fit. The application is in production columns for hydrocarbon wells.
