Invention refers to a method for conditioning wellbore fluids and to a sucker rod to accomplish the method used in the field of petroleum production. The method the invention refers to involves fact that the injection of the conditioning fluids is done directly through the sucker rods, from the surface, concomitantly pumping (producing) the well, being possible that the conditioning fluid be distributed either in the production tubing, or in the wellbore or even in the reservoir rock around the wellbore, concomitantly pumping the well. The sucker rod designed for the application of the method is made of steel and it has two sucker rod heads (1) which are tubular, welded to the ends of a tube (2) made of steel, thus forming a continuous tube through which a fluid can flow or an electric or optical cable can be pulled through, or set inside.

L'invention concerne un procédé permettant de conditionner des fluides de puits de forage et une tige de pompage conçue pour réaliser le procédé utilisé dans un champ de production de pétrole. Selon le procédé de cette invention, l'injection des fluides de conditionnement s'effectue directement à travers les tiges de pompage de la surface, parallèlement le pompage (production) du puits est possible du fait que le fluide de conditionnement est distribué dans les tuyaux de production ou dans le puits de forage ou même dans la roche-réservoir autour du puits de forage, simultanément au pompage du puits. La tige de pompage conçue pour l'application de ce procédé est constituée d'acier et présente deux têtes (1) tubulaires, soudées aux extrémités d'un tuyau (2) en acier, ce qui permet de former un tuyau continu à travers lequel un fluide peut s'écouler ou un câble électrique ou optique peut être amené ou fixé à l'intérieur.
