| Abstract: | On the basis of Biot theory,the basic equations on the hot fluid—solid coupling seepage are derived,and the mathematical model describing the thermal seepage is established.The dynamic dispersion distributing probability formula of the hot fluid and its coefficient expressions are presented.The displacement field of micro-pressure hot fluid is established,and the effect of the dynamic dispersion of the hot fluid on the boundary of porous media is discussed,and the equations for describing the dynamic boundary of porous media are established.In accordance with different outer factors,four boundary models and their dynamic simulations are presented. |

| Keywords: | hot fluid—solid coupling porous medium thermo-saturation zone |
