Numerical Study on the Acoustic Field of a Deviated Borehole with 2.5D Method
Publié en 2014
In this paper, we use the PDE interface of COMSOL Multiphysics® software to implement the 2.5D frequency wave-number domain method to investigate the wave propagation in a deviated borehole penetrating a transversely isotropic formation. A convolutional perfectly matched layer is realized to eliminate the reflections from the artificial truncation boundary. With this method, we can obtain the mode distribution, the dispersion curve and the wave form in time domain. It is easy to analyze other similar model with a little modification.
