The action of water-gas flow and solid-deformation coupling is a complex physical phenomenon during the course of coalbed methane production. To accurately describe this phenomenon, this paper establishes two-phase flow equation and solid-deformation equation respectively and applies finite element method to disperse them, then the coupling method of numerical solution of these equations is discussed in this paper.
