Investigation on Coal Skeleton Deformation in CO2 Injection Enhanced CH4 Drainage From Underground Coal SeamFrontiers in Earth Science - Tập 9
Chaojun Fan, Lei Yang, Gang Wang, Qiming Huang, Xiang Fu, Haiou Wen
To reveal the evolution law of coal skeleton deformation during the process of
CO2 flooding and displacing CH4 in coal seam, a fluid-solid coupling
mathematical model of CO2 injection enhanced CH4 drainage was established based
on Fick’s law, Darcy’s law, ideal gas state equation, and Langmuir equation.
Meanwhile, numerical simulations were carried out by implementing the
mathematical model in the... hiện toàn bộ
Fractal characteristics and theirs influence on methane adsorption in high-rank coals with NMRFrontiers in Earth Science - Tập 10
Wei Jiang, Ying Zhou, Caifang Wu, Mingyang Du
To further understand the pore structure characteristics and their effect on CH4
adsorption capacity for high-rank coals. Based on 11 fresh coal samples from the
Zhina coalfield of South China. We analyzed the pore structure characteristics
of coal samples by low-temperature liquid-nitrogen adsorption (LP-N2A)
measurements. On the basis of nuclear magnetic resonance (NMR), we obtained the
fractal ... hiện toàn bộ
