Abstract

The permeability evolution of bituminous coal under in situ steam pyrolysis was studied combing with in situ CT technology. The results showed that: 1) Permeability varied negatively logarithm with pore pressure, which is related to adsorption expansion; 2) Permeability changed in a “V” shape with temperature. In a range of 300–400 °C, the coal sample continues to soften under hydrothermal action, the external stress closed the crack, and permeability decayed; 3) At 400–600 °C, the hydrothermal action promoted the pyrolysis of the coal samples and generated more seepage channels. The continuous compression by the external stress on the coal body suppressed the expansion of the pores and fissures. However, the former played a leading role in promoting permeability, and permeability showed a piecewise linear growth. CT results showed that the porosity trend of the coal samples was consistent with that of permeability; 4) Above 400 °C, superheated steam promotes the pyrolysis of the coal samples and improved permeability due to its excellent convection and thermal conductivity, drive effect, and participation in chemical reactions.
