Abstract

Las impíementaciones de la presente invención se relacionan con un cuerpo de bloqueo de un ensamble sacatestigo, ensamble de cabezal sacatestigo, sistema de perforación y método de perforación que permiten un rápido acople y desacople del ensamble sacatestigo. El cuerpo de bloqueo de ensamble sacatestigo comprende un cuerpo tubular, al menos dos aberturas de bloqueo, al menos una ranura de fluido, un primer puerto de fluido y un miembro de accionamiento. En otra modalidad, comprende un cuerpo tubular, un miembro de accionemiento, al menos un puerto de rluidoy al menos una ranura de fIL/ido. Por su parte, ej ensamble de cabezal de sacatestigo comprende un cuerpo de bloqueo, una pluralidad de aberturas de loqueo, un mecanismo de bloqueo, al menos una ranura de fluido y un primer puerto de fluido. El sistema de perforación comprende una sarta de perforación y un ensamble de sacatestigo. Finalmente, el método cte perforación comprende insertar un ensamble de nacatestigo dentro de una sarta de perforación, enviare) ensamble sacatestigo a lo largo de la sarta de perforación y rotar la sarta de perforación.
