BOTTOMHOLE ASSEMBLY MODELING

A method for forming a model of a bottom hole assembly (BHA) in a borehole, wherein the BHA is connected to a drill string. The method may further comprise segmenting the model into one or more segments and solving a multipoint boundary value problem (BVP) based at least in part on the one or more s...

Zusammenfassung:	A method for forming a model of a bottom hole assembly (BHA) in a borehole, wherein the BHA is connected to a drill string. The method may further comprise segmenting the model into one or more segments and solving a multipoint boundary value problem (BVP) based at least in part on the one or more segments. L'invention concerne un procédé de formation d'un modèle d'un ensemble de coup de fond (BHA) dans un trou de forage, le BHA étant relié à un train de tiges de forage. Le procédé peut en outre comprendre la segmentation du modèle en un ou plusieurs segments et la résolution d'un problème de valeur de limite multipoint (BVP) sur la base, au moins en partie, desdits segments.
