A rod guide is provided for use in a rotating rod string (12) for powering a progressive cavity pump (14) for pumping downhole fluids through tubing (16) to the surface. The rod guide includes a rotor sleeve (20) secured to the rod string and having a plurality of circumferentially spaced exterior surfaces (22) each positioned substantially along an exterior of a cylinder. The rotor sleeve also includes one or more stop surfaces (24) for limiting axial movement of a stator sleeve (40) with respect to the rotor sleeve, and two or more axially extending cavities (26) each extending from a bottommost surface to an opposing uppermost surface of the rotor sleeve and passing through the one or more stop surfaces. Stator sleeve (40) surrounds the rotor sleeve and has an interior surface (42) for engaging the plurality of circumferentially spaced exterior surfaces of the rotor sleeve, and a plurality of ribs (44) extending outward from two or more outer cylindrical surface portions (44) of the stator sleeve.

Guide de tige utilisé dans un train de tiges rotatif (12) alimentant une pompe à rotor hélicoïdal excentré (14) pour pomper des fluides de fond à la surface par la colonne (16). Le guide de tige comprend un manchon de rotor (20) fixé au train de tiges et doté d'une pluralité de surfaces extérieures circonférentielles espacées (22) et situées essentiellement le long de l'extérieur d'un cylindre. Le manchon de rotor comprend également une ou plusieurs surfaces de butée (24) pour limiter le mouvement axial du manchon de stator (40) par rapport au manchon de rotor, ainsi que des cavités s'étendant axialement (26) de haut en bas le long du manchon de rotor et traversant la ou les surfaces de butée. Le manchon de stator (40) entoure le manchon de rotor et comporte une face intérieure (42) entrant en contact avec la pluralité de surfaces extérieures circonférentielles espacées du manchon de rotor, ainsi que plusieurs nervures (44) saillant des parties extérieures de la surface cylindrique (44) du manchon de stator.
