Abstract

Una barrena expandible para un pozo de sondeo tiene múltiples elementos de soporte (202) distribuidos alrededor de un eje central de la herramienta con cortadoras (234, 236) y almohadillas de estabilización (250) en los elementos de soporte, dispuestos de forma tal que al menos uno de los elementos de soporte comprenda al menos una región que comprende cortadoras y al menos un elemento de soporte comprenda una almohadilla de estabilización con una superficie delantera posicionada para enfrentarse a la pared del pozo de sondeo. El escariador incluye un mecanismo de accionamiento para expandir los elementos de soporte (202) radialmente hacia afuera desde el eje central. Los elementos de soporte difieren en la presencia o posiciones axiales de las almohadillas de estabilización (250) sobre estos tal que al menos un elemento de soporte difiere de al menos otro elemento de soporte en la presente o posición axial de al menos una almohadilla de estabilización. Esta disposición permite que las almohadillas de estabilización ocupen todo el calibre, o casi todo, reduciendo así la vibración.
