Abstract:

A tubing centralizing apparatus has a centralizer body including opposing end portions, a central passage extending through the opposing end portions, and a plurality of apertures extending therethrough between its exterior side surface and the central passage. The apertures are uniformly spaced about a longitudinal axis of the central passage. Bow springs are mounted on the exterior side surface of the centralizer body such that a central portion of each one of the bow springs is bowed away from the centralizer body. The tubing sub is slideably positioned within the central passage of the centralizer body. One of the tubing joint collars is attached to each end portion of the tubing sub. The tubing joint collars and the centralizer body are jointly configured such that the tubing joint collars engage the centralizer body for constraining the tubing sub within the central passage of the centralizer body.
