ABSTRACT:
A centralizer10for mounting on a tubular member such as a section of casing, together with one or more stops42, 48for retaining the centralizer thereon. The stops42, 48are provided with profiles for engaging the centralizer to restrict rotation thereof. The centralizer10may be selectively permitted or restricted from rotation by selection of appropriate stops, and by relative movement of the stops and centralizer on the tubular. Certain embodiments of the centralizer10may also include blades14on the body thereof, the blades being formed such that the velocity and kinetic energy of fluid flow across the blades is altered, so reducing settling of drill cuttings within the bore and on the centralizer.
