Enhanced Coalbed Methane

Thermal stimulation is a useful supplementary mining technique for the enhancement of coalbed methane recovery. This technique couples the temperature change with gas-water two-phase flow in the mining process. Many integer dimension hydro-thermal models have been proposed but cannot well describe this coupling because two-phase flow and heat conduction are usually non-linear, tortuous and fractal. In this study, a fractal-hydro-thermal coupling model is proposed to describe the coupling between heat conduction and two-phase flow behaviors in terms of fractional time and space derivatives. This model is analytically solved through the fractal travelling-wave method for pore pressure and production rate of gas and water. The analytical solutions are compared with the in-situ coalbed methane production rate. Results show that our proposed fractal-hydro-thermal model can describe both heat and mass transfers in thermal stimulation enhanced coalbed methane recovery.

Mechanism Of Interaction

In this paper, the author investigated the research on coalbed methane and water two phase flow, from microscale to macroscale and field engineering studies. The literature research shown that the microflow in pore scale should pay more attention, especially the mechanism of interaction between gas and water, interaction between fluid flow, adsorption, deformation and even thermal field.
