【摘要】 煤层甲烷运移包含解吸、扩散和渗流过程,同时又存在渗流场、变形场和应力场的动态耦合作用,本文建立考虑解吸、扩散过程的气、水两相流渗流场与煤岩体变形场以及物性参数间耦合作用的多相流体流固耦合渗流模型并进行了数值模拟,通过试井资料的实际数据与流固耦合模型的数值模拟的结果比较表明流固耦合模型比较接近实际。更多还原

【Abstract】 Methane and water in coalbed reservoir and coal-body interact including desoption and diffusion process in the course of methane development, in the paper the author gave the fluid-solid-coupling mathematical model of coalbed deformation and two phase fluid(methane and water) seepage considering desoption and diffusion process ,to prove the model ,a practical problem is taken as an example ,the interact model numerical results according with the practical problem better than the rigid model.更多还原
