Abstract

UNA PERFORADORA HIDRAULICA PARA ROCA EN UN POZO DE SONDEO ESTA ADAPTADA PARA SER DIRIGIDA MEDIANTE LA PRESION DEL AGUA. EL FLUIDO DE CONDUCCION CONSUMIDO ES UTILIZADO COMO UN MEDIO DE LIMPIEZA PARA LIMPIAR CON UNA DESCARGA DE AGUA LOS RESIDUOS FUERA DEL POZO DE SONDEO. EL MARTILLO NEUMATICO (20) ESTA GUIADO EN SUS EXTREMOS DELANTERO Y TRASERO Y UNA CAMARA PRESURIZADA CONTINUAMENTE (28) SE EXTIENDE ALREDEDOR DEL MARTILLO NEUMATICO EN TODA LA DISTANCIA ENTRE LAS DOS PORCIONES DIRECTRICES (22,27). LA PORCION DIRECTRIZ FRONTAL (22) TIENE UN DIAMETRO MENOR QUE LA PORCION DIRECTRIZ TRASERA (27), DE MANERA QUE EL MARTILLO NEUMATICO TENGA UN AREA DIFERENTE EN LA CAMARA (28). ENTONCES, LA PRESION EN LA CAMARA (28) PROPORCIONARA UNA FUERZA CONTINUA HACIA ATRAS SOBRE EL MARTILLO NEUMATICO Y CAUSARA EL RETORNO DEL MARTILLO NEUMATICO CUANDO UNA VALVULA CONTROLADORA DEL CILINDRO DE LA CAMARA (34) EN EL EXTREMO TRASERO DEL MARTILLO NEUMATICO SEA DESPRESURIZADO.
