The centralizer is a cementing tool. It is simple in manufacturing, beautiful in structure, firm and durable, and strong in centering force. It overcomes the inadequacy of the original welding-type centralizer that is prone to desoldering, and is a centralizer that can guarantee the quality of well cementing.

Centralizers can be divided into two categories according to the style, elastic centralizer and Rigid Centralizer, each style can also be subdivided; according to the specification size from 3 1/2in to 20in; according to the material can be divided into cast steel, cast aluminum, resin Wait.

A wide variety of centralizers can be divided into rollers, sliders, and automatic commutators by structure. The centralizers of different structures and materials are suitable for different types of eccentrically ground oil wells. The key technology for using centralizers to prevent eccentric wear is the position, spacing and number of centralizers installed.
