Centralizer drilling engineering tools to prevent the inclination change.The overall spiral stabilizer (overall triple helix structure is divided into the overall four-helix), whole straight edge stabilizer roller stabilizer change spiral stabilizer, non-rotating stabilizer. Cementing the casing centralizer (spring CENTRALIZER), sucker rod centralizer (energy coupling) in the tubing to prevent sucker rod wear pipeline. Directional wells with short spiral stabilizer, stabilizer ball, tapered stabilizer can change stabilizer. The non-rotating stabilizer from the casing or openhole wells righting role. The key is you raise the protruding parts of the centralizer righting with (that is, the work surface), the normal drilling should be a positive spiral. Spiral stabilizer stabilizing effect, but since drilling difficulties easy balling. Straight flute structure is simple and easy processing, but the wellbore cutting serious so now the most common is the spiral stabilizer.
