METHODS AND SYSTEMS FOR MODELING AN ADVANCED 3-DIMENSIONAL BOTTOMHOLE ASSEMBLY

摘要

In accordance with some embodiments of the present disclosure, methods and systems for modeling an advanced 3 -dimensional bottomhole assembly are disclosed. The method may include determining a drill string property for a drill string having a rotary steerable drill bit; determining a drilling parameter for a drilling operation; generating a finite element model of the drill string based on the drill string property and the drilling parameter; performing a vibrational analysis of the finite element model; and predicting a drill string behavior during the drilling operation based on the vibrational analysis, the drill string behavior including a directional behavior, rate of penetration, or drilling efficiency of the rotary steerable drill bit.
