Centralizer Mechanical Properties

The mechanical properties of centralizers mainly include bending stiffness and radial supporting force, which must ensure structural stability when subjected to drill string eccentric loads downhole. The elastic deformation range needs to match the casing clearance to avoid excessive wear or jamming, and it must also have fatigue resistance to adapt to long-term vibration environments.

Under dynamic conditions, the influence of fluid impact force and friction coefficient should be considered, and the material hardness and surface treatment process should be optimized. Simulation analysis can verify its critical buckling load, ensuring that it maintains effective centering and guiding functions in complex wellbore trajectories.
