    摘要: A composite material centraliser (60) for a tubular (50) is formed from a shell (10) of elongate shape with a curved upper surface (12) and a longitudinal slot (14) formed centrally in the curved upper surface (12) of the shell (10). At least one port (19) for injection of a bonding agent into the cavity (26) is provided in the curved upper (surface (12) of the shell (10). Fluid vent holes (17) are provided in the curved upper surface (12) of the shell (10) adjacent to either end of the longitudinal slot (14) in the curved upper surface (12) of shell (10). An elongate resilient member (30) with an outwardly projecting bow spring surface (33) may be retained within the longitudinal slot (14) in the shell (10) by insertion of ends (31, 32)in respective recesses (24, 24′).
