Claim:
A tubing centralizing apparatus, comprising: a centralizer body terminating with opposing end portions and a central passage extending through the centralizer body, including said opposing end portions, wherein the centralizer body includes at least one aperture extending between an exterior side surface of the centralizer body and the central passage of the centralizer body and extending lengthwise between the opposing end portions; a plurality of resilient members mounted on the centralizer body, wherein each one of said resilient members is in the form of an elongated strap having opposing end portions, wherein a first one of said end portions of each one of said resilient members is attached to the centralizer body adjacent one of said end portions of the centralizer body in a manner whereby a second end portion thereof extends toward the other one of said end portions of the centralizer body and wherein a central portion of each one of said resilient members is spring biased away from the centralizer body; a tubing sub slideably positioned within the central passage of the centralizer body and having opposing end portions; a first tubing joint collar attached to a first one of said end portions of the tubing sub, wherein the first tubing joint collar and the centralizer body are jointly configured for precluding the first tubing joint collar from passing through the central passage; and a plurality of protruding members extending from an interior surface of the central passage, wherein said protruding members and the tubing sub are jointly configured such that the protruding members approximately center the tubing sub within the central passage of the centralizer body and wherein said protruding members are symmetrically spaced about a longitudinal axis of the central passage and wherein the plurality of protruding members and the plurality of resilient members are offset such that the plurality of protruding members are located on the interior surface of the central passage of the centralizer body at a different position from where the plurality of resilient members are located on the centralizer body.
