Abstract

A stabilizer (10) for a drill string (13) and drill bit (17) is mounted behind the drill bit in the drilling assembly. The stabilizer (10) comprises a tubular body (12) having one or more stabilizer blades (18) mounted thereon. The stabilizer blades (18) extend radially outwardly from the stabilizer body (12). In a first position, the stabilizer blades (18) are in vertical axial alignment behind the drill bit (17). Drill string pressure is utilized to release a locking mechanism (36 and 38) permitting relative rotation between the stabilizer blades (18) and the stabilizer body (12) thereby rotating the stabilizer blades (18) to a second position providing stabilization for the drill string (13) and drill bit (17).
