Abstract

1.- Una mecha perforadora con percusión para perforar una formación de tierra subterránea. Dicha mecha tiene un eje central longitudinal y se opera aplicando un movimiento de percusión axial repetitivo a lo largo del eje sobre la mecha perforadora y movimiento de rotación alrededor del eje con respecto a la formación de tierra subterránea. La mecha perforadora está compuesta por:uno o más cortadores axiales para cortar predominantemente de forma axial una formación de tierra subterránea en respuesta a los impactos de percusión axiales;uno o mas cortadores de cizalla para cortar predominantemente en cizalla una formación de tierra subterránea en respuesta a los movimientos de rotación; en los que:hay un primer cortador de cizalla del o de los cortadores de cizalla, y para los cuales uno o más cortadores axiales se disponen con respecto al menos al primer cortador de cizalla de tal forma que contacten con la formación de tierra subterránea antes, durante el impacto de percusión, que al menos el primer cortador de cizalla.
