Abstract

Un mecanismo para mejorar la separación de las porciones del ensamble de uno a otro cuando se disponen en un pozo. El mecanismo puede disponerse en una barra interna del ensamble de liberación y configurarse para evitar que la resistencia friccional desplace la barra. Por lo tanto, el accionamiento de liberación puede asegurarse, por ejemplo, a pesar de cualquier tracción axial del ensamble que puede tender a las fuerzas radiales directas sobre la barra. Como tal, se puede asegurar la separación controlada de las porciones del ensamble de liberación mientras que ayuda a la remoción de una línea acoplada al ensamble desde el pozo.
