Abstract

A drill string is comprised of a vibration damping drill pipe section, made of a material such as aluminum alloy, titanium, composite material, or ductile iron, for example, and another drill pipe section made of a different material, such as conventional steel. The vibration damping drill pipe section may be place in any desired location, such as near sensitive equipment, such as a bottom hole assembly. Additional vibration damping sections may be interspersed with conventional drill pipe. The vibration damping drill pipe helps to reduce vibration experienced by the drill string during drilling, particularly torsional and lateral vibration.
