Abstract

This paper tries to use the finite element analysis software ABAQUS to build the model and get images of rock stiffness degeneration, then get the displacement velocity and acceleration curves of drill and drill bit to express the longitudinal, transverse and torsional vibrations, as well as random access collision with hole wall . It aims at analyzing the incremental changes in these structure of rocks when destruction and disturbance happens in order to avoid the drilling accident which caused by the changes which are difficult to observe in the general physics experiment.
