(FR) OUTIL DE FORAGE DIRECTIONNEL
Abstract: front page image
(EN)Directional drilling tool (13, 14) comprising a cutting structure formed of blades on which there are cutting edges (13) and a guard (11) that stabilizes the tool against the wall of the well (3), characterized in that the guard comprises a plurality of passive pivoting blades (16) each of which can pivot about a pivot pin (18) inserted in the guard (12) near its boundary with the cutting structure under the action of thrusting and/or damping members, so that when the pivoting blades (16) are in their nominal position, the guard (12) of the tool (1, 14) exhibits a substantially cylindrical shape.
(FR)Outil de forage directionnel (13, 14) comportant une structure de coupe, formée de lames sur lesquelles sont disposées des taillants (13), et une garde (11) assurant la stabilisation de l'outil contre la paroi du puits (3), caractérisé en ce que la garde comporte une pluralité de lames pivotantes (16) passives pouvant pivoter chacune autour d'un axe (18) inséré dans la garde (12) à proximité de sa limite avec la structure de coupe sous l'action d'organes de poussée et/ou d'amortissement, de sorte que lorsque les lames pivotantes (16) sont dans leurs position nominales, la garde (12) de l'outil (1, 14) présente une forme sensiblement cylindrique.
