The interaction mechanism among gas, water and rock plays a significant role in earth exploration, including CO2 geological sequestration, CBM, ECBM and wet dedusting in underground engineering. These fields often involve multiphysics and multiphase coupled reactions. For example, the hydraulic stimulation technology for enhancing coalbed methane is usually accompanied by the interaction of gas, water and rock, as well as controlled by the thermal-fluid-solid physics field. Actually, it has made significant progress in gas-water-rock interaction and multi-physical field coupling mechanism over the past few decades: i: the evolution mechanical properties of water/gas-bearing rock; ii, the transport mechanism of two-phase fluid in the reservoir. However, we are facing some new problems as earth exploration gradually enters the deep stage. Including but without limitation, i: how to realize CO2 geological storage efficiently; ii: how to realize efficient gas extraction in deep coal seams; iii: how to realize coal seam water injection (including hydraulic fracturing) efficiently in gas-bearing coal seams to control gas and dust disasters.
The specific objectives of this research topic are to, i: scrutinize the research progress of gas-water-rock interaction and multi-physical field coupling mechanism; ii: address solutions to the difficulties occurring in CBM, ECBM and CO2 geological storage; iii: Establish a new theoretical system in gas-water-rock interaction.
This topic welcomes the research article and review on the gas-water-rock interaction and multi-physical field coupling mechanism. Potential topics include, but are not limited to:
• Two-phase flow in porous media
• Mechanical properties of rocks in multiple physical fields
• Coal seam stimulation technology
• CO2 geological storage
