Abstract
La presente invención se refiere a una herramienta de perforación a percusión asistida por fluido (1) que comprende una manga externa de desgaste (2) que comprende una pared sustancialmente cilíndrica (3) y que tiene superficie interna (4) y externa (5). La herramienta también comprende una broca percutora (6) que tiene una parte de cabeza (7) y una parte que retiene la broca (8) y que está ubicada en un extremo delantero (9) de la manga externa de desgaste. La herramienta además comprende un pistón de deslizamiento (10) que está instalado para que exista un movimiento de vaivén dentro de la manga externa de desgaste para impactar la broca percutora. La herramienta también incluye un anillo de accionamiento (11) que tiene una pared sustancialmente cilíndrica (12) y que comprende un medio de conexión (13) que está adaptado para conectar el anillo de accionamiento con un medio de accionamiento de la herramienta de perforación a percusión asistida por fluido. Al menos un canal de descarga (31) provee una trayectoria de fluido hacia la cara cortante de la broca para un medio de barrido. Una primera parte (32) del al menos un canal de descarga se extiende longitudinalmente dentro de la pared (3) de la manga de desgaste, una segunda parte (36) del al menos un canal de descarga se extiende longitudinalmente dentro de la pared (12) del anillo de accionamiento y una tercera parte (40) del al menos un canal de descarga se extiende a través de la parte de la cabeza (7) de la broca percutora hacia la cara cortante (43) de la broca.
