Abstract

La presente invención se relaciona con una cabeza de herramienta de fondo de pozo (1) que se monta sobre una herramienta de fondo de pozo (10) para perforar en el fondo de pozo de un depósito o yacimiento o para liberar sólidos precipitados (2), como hielo, incrustaciones o lo similar, en un fluido de cavidad en una tubería, una tubería de revestimiento (3), un pozo o cualquier fondo de pozo de una cavidad. La cabeza de herramienta de fondo de pozo comprende un cuerpo cilíndrico hueco (4) con una pared circunferencial (5) que se extiende de una parte base del cuerpo, la pared circunferencial tiene un reborde circunferencial (6) en su extremo opuesto a la parte base. El reborde circunferencial (6) comprende una pluralidad de bordes (8) para cortar, triturar, perforar y/o moler, en donde la parte base tiene una pluralidad de orificios de paso (9) para dejar que pase por ellos el fluido de cavidad que contiene sólidos precipitados.
