Centralizer Anti-Wear Design

Centralizer anti-wear design requires optimizing the contact surface structure and using wear-resistant alloys or non-metallic composites to reduce the friction coefficient. Rollers or sliding bearings can be added to key parts to disperse contact stress, and self-lubricating grooves can be designed to reduce adhesive wear.

Structurally, dynamic centering ability should be ensured to avoid local overload. Combine downhole condition simulation to analyze wear hotspots, extend tool life through surface hardening treatment or replaceable wear-resistant blocks, and regularly monitor wear data to guide maintenance.
