摘要
气 -水二相流和煤岩变形耦合作用是煤层气产出过程中一种复杂的物理现象 ,为准确描述这一现象 ,本文建立了气 -水二相流和煤岩变形的微分方程 ,并用有限元分别将它们进行离散化 ,然后讨论了煤岩变形模型和气
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.
