Abstract
In drilling processes, dynamic vibrations are the leading causes of damages to drilling equipment. This damage can happen on the borehole wall, the drill string, and at the bottom hole assembly. The sources of these vibrations are the dynamic forces applied on the drill bit that develop when driving through various underground geological formations, mainly rock and sediment. As a result, these vibrations traverse the drill string as a cyclic waveform, causing deformations and inevitable fatigue of the drill string. Our goal was to investigate these disturbances through state delay analysis.
