Mechanisms and Multi-Field-Coupled Responses of CO2-Enhanced Coalbed Methane Recovery in the Yanchuannan and Jinzhong Blocks Toward Improved Sustainability and Low-Carbon Reservoir Management
Experimental insights reveal how CO2 injection improves methane production in coal reservoirs, suggesting enhanced sustainability and greenhouse gas reduction.
Key Points
This research examines how CO2 enhancements impact coalbed methane recovery and reservoir management.
Investigated CO2 modification effects on coal reservoirs via experimental and numerical approaches.
Analyzed the interactions of CO2 adsorption, fracture dynamics, and geochemical processes.
Evaluated injection pressure's role in CO2 migration, permeability evolution, and methane recovery.
CO2 enhances methane production and supports greenhouse gas reduction strategies.
Adsorption swelling leads to initial permeability reduction, while higher pressures improve flow dynamics.
Optimal pressure levels balance injectivity and long-term storage integrity.
