What are the key techniques for improving drill string stability?

Preventing vibrations involves many key aspects. Ensure proper gradation and minimize gaps between rings. Keep the drilling tools steady—no shaking or jolting. On the rig, maintain straight drill pipes without any bends. Monitor drilling and pumping pressures carefully, staying well within specified limits. Use a lightweight, flexible hose for the small faucet. When breaking through challenging formations, avoid excessive rapid rotation. Additionally, employ an emulsified solution to significantly reduce vibration. Finally, incorporate mechanical vibration dampeners and use stabilizers to further counteract both lateral and longitudinal oscillations—this is the surest way to prevent unwanted vibrations altogether.
