The Study on Vibration of Drill String of ERW

2008 International Conference on Computer Science and Software Engineering, 2008
During exploitation of extended reach well (ERW) drilling engineer, the problem of drill string failure is very serious; drill string vibrations are main reasons. In this paper drill string of extended reach well of different part is object being studied. The models about various vibrations are set up. Modal vibrations of drill string are studied.

Drilling String Vibration: Modelling and Simulation

Volume 11A: Honoring Symposium for Professor Carlos Guedes Soares on Marine Technology and Ocean Engineering, 2018
The offshore industry has a significant impact on the global economy and it is expected to grow over the next 4 years. A crucial part of an offshore structure is the drill string. Drill strings can be seriously damaged by vibration during drilling operations. The control of vibrations in drill strings is essential.

Effects of Drill String Length on Stick–Slip Oscillation of the Oilwell Drill String

Iranian Journal of Science and Technology, Transactions of Mechanical Engineering, 2019
It has been demonstrated by numerous field data that the stick–slip phenomenon tends to appear in deep wells. However, the explanation for this phenomenon has scarcely been studied. Based on a torsional pendulum model, the relationship between stick–slip oscillation and drill string (DS) length is studied in this work.
