Abstract

SE REFIERE A HERRAMIENTAS DE PERFORACION QUE PUEDEN USARSE PARA PERFORAR FORMACIONES GEOLOGICAS Y/O ARTIFICIALES. LAS HERRAMIENTAS DE PERFORACION QUE TIENEN VIAS DE AGUA DE SECCION DECRECEINTE AXIALMENTE QUE PUEDEN AUMENTAR EL ARRASTRE Y LA VIDA DE LA BARRENA DE PERFORACION, MIENTRAS QUE TAMBIEN DISMINUYE LA OBSTRUCCION. LAS VIAS DE AGUA PUEDEN TENER SECCION DECRECIENTE RADIALMENTE ADEMAS DE TENER SECCION DECRECIENTE AXIALMENTE. LAS VIAS DE AGUA DE SECCION DECRECIENTE AXIALMENTE PUEDEN INCLUIR MUESCAS QUE SE EXTIENDEN HACIA LA CARA DE CORTE DE LAS HERRAMIENTAS DE PERFORACION Y/O RENDIJAS ENCERRADAS DENTRO DE LA CORONA DE LAS HERRAMIENTAS DE PERFORACION. TAMBIEN SE REFIERE A SISTEMAS DE PERFORACION QUE INCLUYEN HERRAMIENTAS DE PERFORACION QUE TIENEN VIAS DE AGUA DE SECCION DECRECIENTE AXIALMENTE, Y METODOS DE FORMACION DE HERRAMIENTAS DE PERFORACION QUE TIENEN VIAS DE AGUA DE SECCION DECRECIENTE AXIALMENTE
