| 摘 要： | 在煤层气的开采过程中，煤体变形与流体流动是相互耦合作用的。由于甲烷气的解吸热效应，煤层气的渗流又是一个非等温过程，因此对渗流场、变形场及温度场耦合作用下煤层气的渗流规律进行研究具有重要的意义。本文综合利用流体力学、岩石力学和传热学理论，给出了考虑温度场、流体渗流场和变形场作用下的水－煤层气两相流体渗流理论，并给出其耦合求解的方法，通过数值模拟的方法，研究了温度铲应对煤层气开发的影响。

| Abstract: | During the development of coal-bed methane, the deformation of coal skeleton and fluid flow in it is interacted. Because of coal-bed methane adsorption and de-sorption, the coal-bed methane flow is a an-isothermal procedure. Based on the fluid mechanics and rock-soil mechanics and diathermanous theory, the model for thermo-hydro-mechanical coupled flow is built. Through digital simulation, studies are made of how temperature effect acts on the development of coal-bed methame. |
