Abstract

La presente invencion está comprometida con un sistema eléctrico de calentamiento de cavidad descendente (10) para el tratamiento térmico de formacion en el yacimiento de la produccion de petroleo y gas. El calentador (10) contiene cámara de cableado (12), cámara de calentamiento (16) y cámara de enfriamiento (14), separadas, siendo la ultima insertada entre la cámara de cableado (12) y la cámara de calentamiento (16). El tratamiento térmico se lleva a cabo insertando el calentador (10) en un barreno que se trata. Un gas, preferiblemente nitrogeno o aire, es conducido al calentador con un alojamiento o tubo (24). El gas va a través de la cámara de cableado (12) y la cámara de enfriamiento (14), y es calentado siguiendo una trayectoria sinuosa en la cámara de calentamiento (16) antes de que sea expulsado del calentador (10).
