Abstract

Una herramienta de tratamiento de multiples posiciones de un pozo, transportada por tuberia, que tiene un alojamiento tubular y un miembro interno tubular, los cuales se pueden colocar relativamente en las posiciones de "Colocacion", "Tratamiento", "Descarga" y "Liberacion", accionadas por un mecanismo de colocacion mecanico. Este mecanismo de colocacion se carga por un resorte, tal como un resorte de gas comprimido o un resorte mecanico, que empuja el alojamiento tubular en alejamiento de la conexion de tuberia del miembro tubular interno, no requiriendo asi fuerzas de establecimiento para el impulso o indice de la herramienta. La herramienta de tratamiento es anclada dentro del revestimiento del pozo por botones accionados por la presion hidraulica, eliminado asi el requerimiento tipico para la actuacion del anclaje por las fuerzas de establecimiento. La herramienta de tratamiento se sella dentro del revestimiento por los empacadores energizados por presion, que son activados por la presion hidraulica del fluido suministrado de la tuberia. La herramienta suministra un pasaje de desviacion par permitir la comunicacion de las zonas arriba y debajo de la herramienta, mientras aislan el intervalo montado que se va a tratar.
