Patent

CA 2404885

A threaded joint for oil well pipes is provided which can guarantee a joint efficiency sufficient for practical use in deep wells, which has a decreased joint outer diameter, and which has an improved bending resistance, compression resistance, and over-torque resistance which are sufficient for use by the side track technique. It is an integral threaded joint for oil well pipes in which it has a joint efficiency of at least 70%, the outer diameter of the joint is larger than and at most 1.08 times the outer diameter of the oil well pipe bodies, and the threaded portions have a cross section of a trapezoidal shape with a load flank angle (.alpha.) of the threads in the range of 0 to -20 degrees and a stabbing flank angle (.theta.) thereof in the range of 35 to 50 degrees.

L'invention concerne un raccord fileté de tuyaux pour puits de pétrole d'un système intégré, capable d'assurer une étanchéité pour résister à une utilisation pratique en tant que raccord de tuyaux pour puits de pétrole profond. A cet effet, le diamètre externe dudit agencement est réduit et les capacités de résistance à la flexion, aux compressions et aux serrages exagérés, nécessaires dans un système de déviation, sont augmentées. Dans ladite invention, ledit raccord offre une efficacité d'au moins 70 %, présente un diamètre extérieur d'au maximum 1,08 fois supérieur au diamètre extérieur d'un corps principal de tuyaux de puits de pétrole et une section transversale partielle filetée présente un filetage trapézoïdale avec un angle (y) de flanc de surface de charge du filet de 0 à 20 degrés et un angle (x) de flanc de surface d'insertion du filet de 35 à 50 degrés.
