Abstract

- Oil well equipment.
- The equipment includes:

. a launch tube (30) partly communicating with the internal casing and extending downward from the installation tool, . a basket (31) secured at the launch tube bottom part, with a cross section smaller than that of the internal casing, open at its bottom end and containing at least one plug (33) with peripheral lips (35), . a launching device, internally slidable in the launch tube and including an axial push rod (38) cooperating with the plug and a piston (37) integral with the plug, axially kept stationary in the tube by a limited strength stopping means (40).
- Application for off-shore drilling.
