Description
Casing Rigid Spiral Centralizer Non-welded Bow Spiral Centralizer
The main structure of the casing centralizer consists of a main body, a slip centralizer sleeve,a piston,a self-locking mechanism etc.
The casing stabbing device is inserted into the well with the casing, and when the pressure rises to 10-12Mpa, all stabbing devices in the well work. The stabbing slips are tightly attached to the inner wall of the casing or the inner wall of the open hole, allowing the casing to be supported and stabbed. The stabbing device itself has a locking mechanism, which can ensure that after the pressure is released, the stabbing slip can still stick tightly to the inner wall of the casing until it is solidified and completed, and can always center and straighten the casing.
Characteristics of casing stabilizer
1. Ensure that the casing is centered and improve the quality of cementing.
2. Simple structure, flexible piston, and good sealing performance.
3. The outer diameter is small and not easily obstructed.
Rigid stabilizers typically adopt an integrated structure to achieve higher strength, typically fixed to the stop ring or fixed to the sleeve with fixing screws;
The rigid centralizer provides maximum recovery effect and improves liquid fluidity to improve cementing quality. It can be provided in straight or swirl type, as well as aluminum alloy and cast steel materials.
