Abstract

Una broca de barrena giratoria, para perforar un pozo de perforacion en una formacion de tierra; la broca de perforacion comprende un primer y un segundo discos cortadores, cada disco cortador está arreglado para girar a lo largo del fondo del pozo de perforacion durante la rotacion de la broca de perforadora y, de este modo, realizar cortes radialmente separados, sustancialmente circulares, primero y segundo respectivamente, en el fondo del pozo de perforacion, de modo que un cuerpo de material de roca se defina entre dichos cortes. El segundo disco cortador está arreglado para cortar el fondo del pozo de perforacion en un intervalo de rotacion seleccionado de la broca de perforacion, detrás del primer disco cortador, y para retirar dicho cuerpo de material de roca en direccion del primer corte. Cada disco cortador incluye un grupo de miembros de corte recíprocamente separados arreglados para crear, durante una vuelta de la broca de perforacion, un juego correspondiente de secciones de corte del corte que fuera creado por el disco cortador, y donde los miembros de corte están arreglados de modo que los grupos de secciones de corte creados durante las vueltas subsiguientes de la broca de perforacion queden en relacion escalonada uno respecto al otro.
