Abstract
Estabilizador de herramienta tal como una herramienta de perforación colgada de una columna de perforación, adaptado para ser colocado entre la herramienta y la columna de perforación, coaxialmente a esta última, para mantener la progresión de la herramienta en la dirección seleccionada, estando provisto este estabilizador de un orificio calibrado central y que comprende por lo menos dos aletas u hojas radiales que dejan subsistir entre las mismas unos espacios angulares libres para la circulación de un fluido de perforación hacia el orificio del pozo perforado, caracterizado porque las aletas tienen una configuración tal que definen entre ellas un espacio angular del tipo Venturi.
