摘要:
A method comprising providing a centralizer disposed about a wellbore tubular, wherein the centralizer comprises a first collar, a second collar, a plurality of bow springs coupling the first collar to the second collar, and a plurality of particulates disposed on an outer surface of at least one bow spring, wherein one or more of the first collar, the second collar, and the bow springs comprise a composite material, and placing the wellbore tubular in a wellbore disposed in a subterranean formation. A method comprising providing a centralizer disposed about a wellbore tubular, wherein the wellbore tubular comprises a stop collar, a protrusion, or an upset on either end of the centralizer, and wherein the centralizer comprises three or more collars, a plurality of bow springs comprising a plurality of portions of bow springs, wherein each portion of bow springs couples two adjacent collars, and wherein one or more of the collars and the bow springs comprise a composite material, and placing the wellbore tubular in a wellbore disposed in a subterranean formation.
