Sucker Rod Centralizer

The sucker rod centralizer is a downhole tool for preventing eccentric wear in pumping wells. It is suitable for eccentrically worn pumping wells, especially suitable for eccentrically worn pumping wells and directional inclined wells above the neutral point of the sucker rod, and the neutral point of the sucker rod. Below, with the nylon centralizer on the sucker rod body, the anti-eccentric wear effect is better.

effect:

The sucker rod moves up and down in the tubing. Due to the elastic deformation of the sucker rod, the rod and the tubing wall are prone to friction, and the sucker rod is easy to break off. The sucker rod centralizer has strong flexibility and is in contact with the inner wall of the tubing. Reduce the friction between the rod and the tube, and enhance the oil recovery life of the pumping unit.

structure:

The sucker rod centralizer consists of a coupling, a centralizer sleeve and a short section.

principle:

Connected to the sucker rod, use the outer diameter of the centralizer sleeve to be larger than the outer diameter of the sucker rod coupling for centralizing; use the centralizer sleeve is a high-strength wear-resistant material, contact with the tubing will cause the centralizer to wear and reduce the wear of the tubing. To achieve the purpose of anti-eccentric wear.
