In the method according to the invention, after machining successively respective threaded elements at both ends of the tubular component (10), a second orientation gauge is screwed onto the second threaded element to check whether a mark (4) on the gauge comes into alignment with an orientation mark (11) which has been drawn on the component, after the first element has been machined and a first orientation gauge has been screwed onto the latter in axial alignment with a mark provided on this gauge. If not, the machining of the second element is repeated with parameters varied accordingly. Application to the drilling and operation of hydrocarbon wells.

Dans le procédé de cette invention, après l'usinage successif d'éléments filetés respectifs au niveau des deux extrémités de la composante tubulaire (10), une seconde jauge d'orientation est vissée sur le second élément fileté pour vérifier qu'une marque (4) située sur la jauge soit alignée avec une marque d'orientation (11) qui a été tracée sur la composante, après que le premier élément a été usiné et qu'une première jauge d'orientation a été vissée sur ce premier élément dans un alignement axial avec une marque située sur cette jauge. Si la marque (4) n'est pas alignée, l'usinage du second élément est répété avec des paramètres modifiés en conséquence. L'objet de cette invention s'applique au forage et au fonctionnement de puits d'hydrocarbures.
