Smartphone stabilizer

Drill rods in the hole when the high-speed rotation, to keep the drill pipe smooth operation, so that the drill bit as close as possible to the center line of a tool, also known as centralizer. Steady effect is mainly to reduce the drill string elastic system in the hole in the radial and axial vibration; reduce the drill bit and drill pipe partial wear; to ensure the quality of coring; to prevent the slope or artificial directional drilling. The structure of the stabilizer is relatively simple, with a ribbed piece (straight or spiral) of the thick diameter joints.
Also known as centralizer, is a stable underground drilling tools, anti-oblique role of the tool. Connected to a drill string near a drill rod, used to stabilize the direction of the drilling device.
