Patent attributes
A centralizer is provided for centralizing a tubular, such as a drill pipe, in a wellbore. The centralizer comprises a resilient inner sleeve comprising three or more protruding members extending radially outwardly from an outer surface of the inner sleeve. The inner sleeve receives the tubular and spaces the tubular from the wellbore. The centralizer further comprises an outer support body for receiving the outer surface of inner sleeve. When the inner sleeve is retained between the support body and the tubular, the protruding members project out through windows formed in the support body. The support body and the inner sleeve are retained about the tubular with a pair of annular end collars. A method for replacing worn components of the centralizer is also provided.
