Patent ID: 10077617

Abstract:
An apparatus and method, usable for centering downhole well tools within a pipe or wellbore, comprises a cylindrical end boss extension, from a distal end of a well tool housing, and a thin ring secured about said end boss comprising a plurality of radial apertures. Thin metallic wires, having distal ends secured within said apertures, extend radially from said ring into contact with the inside wall(s) of the pipe or wellbore. An alternative embodiment includes an annular extension from the distal end of said well tool that encloses a cavity within. A plurality of diametrically opposite apertures in said annular extension receives respective wires across a tool housing axis to project in opposite directions into contact with said inside wall of the pipe or wellbore. Said wires may be secured to said well tool by a potting compound, including a high temperature silica compound, an adhesive paste, or other compounds.
