Abstract

The tubular device is designed to be connected to the drill string. Its outer peripheral upper surface (12) has two systems of grooves (20a,21a). The first system of grooves (20) runs obliquely to the longitudinal axis of the device. The second system (21) runs obliquely in the opposite direction to the longitudinal axis. Both systems intersect each other at several points.
