| 摘 要： | 在考虑煤层气溶于水的情况下，探讨了水—气两相流在煤层中的运移规律，建立了煤岩体为弹塑性小变形时煤岩变形场的数学模型，并应用多相渗流力学理论，建立了两相流渗流场模型：通过煤体骨架变形对流体渗流的影响和流体渗流对煤体变形的影响，将有效应力、孔隙流体压力分别引入到渗流物性参数中，实现了流固耦合的相互作用。

| Abstract: | In view of the solution of coal bed methane in water, the transfer law of two phase(water-gas) flow in coal seams is discussed in this paper. The mathematical model of coal mass deformation field under small elastic-plastic deformation of coal is offered and mathematical model of two phase fluid seepage is proposed using multiphase seepage dynamical theory. Through the analysis of the effect of deformation of coal framework on fluid seepage and the effect of fluid seepage on coal deformation, effective stress and hole fluid stress are introduced in the physical parameter of seepage respectively, and the mechanism of fluid-solid-coupling is realized. |
