Abstract

DISPOSITIVO OBTURADOR Y EQUILIBRADOR DE PRESIONES EN MECANISMOS DE PERFORACION. CONSISTE EN UN CONJUNTO DE MANDRIL Y ALOJAMIENTO DISPUESTOS TELESCOPICAMENTE, MOVIBLE ENTRE LAS POSICIONES DE EXTENSION Y RETRACCION ESTABLECIENDO AXIALMENTE PASAJES DE ENSAYO E INFLADO; UNA PRIMERA VALVULA (11) QUE COMUNICA EL PASAJE DE ENSAYO CON LA PARTE DEL POZO UBICADA ENCIMA DE DICHOS OBTURADORES INFLABLES (18, 18 ) PARA IGUALAR PRESION; UNA SEGUNDA VALVULA (13) QUE EFECTUA UNA COMUNICACION SIMILAR A LA PRIMERA PARA PERMITIR LA DEFLACION DEL ELEMENTO OBTURADOR Y UNA ULTIMA VALVULA (17) PARA IMPEDIR LA DEFLACION DEL OBTURADOR CUANDO UNA BOMBA (16) SE HALLE FUNCIONANDO.
