About this document
Non-Linear Dynamics of Drillstring Stabilizers by Paredes Puelles Sammy Cristopher is a document available to read on EtoBox.
This document analyzes the nonlinear dynamics of drillstring vibrations as applied to oilwell drilling. It models the lower section of a drillstring, composed of drill collars and stabilizers, as a rotating mass-spring system moving in a plane perpendicular to the borehole axis. Forces considered include inertial forces from acceleration of the drill collars and drilling fluid, as well as damping forces from the fluid and friction between stabilizers and the borehole wall. Conditions for different types of
