Abstract

1. A method for modifying the trajectory of a cutting tool for a deep directional drilling well, driven either by a hanging motor or a hanging turbine with a rate of at least 700 rot/min or by a rotary table from the surface at a rate of at least 100 rot/min, by means of a stabilizing device having helicoïdal lateral ribs (8) separated by passageways (14) of drilling fluid and provided with a hardfacing material affording good erosion and abrasion resistance, characterized in that at least one substantially circumferential groove is defined in the ribs and located in a plane which is perpendicular to the axis of rotation, so as to interconnected the passageways (14) of drilling fluid.
