The Research on Deformation Analysis of Rigid Packed Hole Assembly Dynamic Model in 3D Borehole
This paper uses cellular element method to propose a new calculating method for drill string dynamic model, and applies the calculating method on rigid packed hole assembly model. The results show that, this method has advantages of programming simply, applying boundary condition easily and rapid convergence rate. It is a new method for rigid packed hole assembly optimization design.
