Dynamic Model and Quantitative Analysis of Stick-Slip Vibration in Horizontal Well
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 ar...
