Abstract:
A centralizer includes one or more centralizer fins radially extending from a body of the centralizer. The centralizer fins may include one or more chambers extending through the outer surfaces of the centralizer fins. The one or more chambers may change shape in response to a compression force being applied to the centralizer fins to cause the centralizer fins to deform. The centralizer fins may be deformed for installation of the centralizer in a drill collar. The centralizer may also include a split-ring clamp for coupling the centralizer to a drilling tool positioned in a through-bore of the centralizer body. The split-ring clamp may apply a load on the drilling tool in response to an end cap being torqued to an end portion of the centralizer body.
