Abstract In one embodiment, a tubular lifting system (100) for lifting a wellbore tubular (12, 6) includes an outer tubular (10); an inner tubular (20) disposed in the outer tubular; an annular chamber (40) defined between the inner tubular and the outer tubular; and a tubular piston (30) selectively movable in the annular chamber, wherein the wellbore tubular is connected to the tubular piston and movable thereby. Dans un mode de réalisation, un système de levage de tubulaires (100) permettant de lever un tubulaire de trou de forage (12, 6) comprenant un tubulaire externe (10); une chambre annulaire (40) définie entre le tubulaire interne et le tubulaire externe; et un piston tubulaire (30) déplaçable de manière sélective dans la chambre annulaire, le tubulaire de trou de forage étant raccordé au piston tubulaire et déplaçable de ce fait.
