Dynamic Model and Quantitative Analysis of Stick‐Slip Vibration in Horizontal Well
Shock and Vibration, Volume 2020, Issue 1, 2020., 2020 Stick‐slip is very harmful to the service life of drillstring. The extended Hamilton principle is applied in the paper. Then, finite element method (FEM) is employed to describe the model. The drillstring‐borehole impact and friction, fluid‐structure interaction, bit‐rock interaction, and gravity are considered in this model. The influence of axial and

On the formation of limit cycle of the friction-induced stick-slip vibration in oilwell drillstring
Petroleum, 2015 In this paper, the stick-slip vibration in oilwell drillstring is studied. The drilling system is modelled as a lumped-parameter torsional pendulum and the interaction between the drill bit and the rock is treated as Coulomb friction.

Nonlinear Dynamic Characteristic Analysis of a Landing String in Deepwater Riserless Drilling
Shock and Vibration, Volume 2018, Issue 1, 2018., 2018 The landing string is an important component of deepwater riserless drilling systems. Determination of the dynamic characteristics of the landing string plays an essential role in its design for ensuring its safe operation. In this paper, a dynamic model is developed to investigate the dynamic response characteristics of a landing string, where a ...
