Abstract

Se describe una herramienta y método para identificar la resistencia relativa de intervalos subterráneos a través de los cuales se ha perforado un orificio de pozo. La herramienta incluye un cuerpo de herramienta capaz de moverse a través de un orificio de pozo. El cuerpo de herramienta tiene almohadillas montadas en brazos móviles. Preferiblemente los brazos pueden cargarse independientemente. Cada almohadilla (42) porta escavadores (14, 16) que se empujan contra la pared del orificio del pozo de manera que crea excavaciones estrechas profundas o anchas superficiales. Preferiblemente, las excavadoras comprenden un cortador de elemento sencillo o doble compacto policristalino (PDC) o material resistente al desgaste, duro, adecuado, tal como carburo de tungsteno o diamante natural, y se empujan contra la pared del orifico del pozo por brazos cargados resilientemente. La profundidad de excavaciones estrechas se mide, por ejemplo, por dos calibradores accionados aleatoriamente y la anchura de escavadores anchos se visualiza por un formador de imágenes del orificio del pozo.
