Particle Based Evaluation of Rock Deformation in Stabilizer-Wall Contact for Drilling Dynamics

摘要

The analysis of drill string deformation during operation has to deal with the restrictions the borehole geometry imposes. For some routine analyses, e. g. static drill string de-formation, it is sufficient to restrict the drill string to the borehole using a methodically convenient formulation. This formulation does not necessarily include true structural properties of the rock forming the borehole wall.
