Abstract
A centralizer apparatus having turbolizer protuberances includes groups of openings for receiving set screws to define a plurality of circumferential and longitudinal points of engagement between the centralizer and a tubular string to which it is attached. Associated with the centralizer is a bonding layer of adhesive material, which is injected through one of the openings while the centralizer is rotated relative to the tubular string to obtain a rigid bond between an outer surface of the tubular string and a majority of the inner surface of the centralizer. The bond can be broken by the external application of heat so that, after also loosening the screws, the centralizer can be removed from the tubular string.
