Abstract

Using three different coalbed matrix shrinkage/swelling models,we comparatively simulated the permeability,methane production,methane content distribution,CO₂ injection and CO₂ storage.It is pointed that the simulated maximum permeability is 6 times of initial permeability of shrinkage/swelling model based on sorption/desorption,and permeability decrease with 2 per cent of initial permeability of shrinkage/swelling model based on pressure changes,and the cumulative methane production of former is 1.3 times of later,without CO₂ injection.The simulated maximum and minimum permeability is 1.25 and 0.17 times of initial permeability of shrinkage/swelling model based on sorption/desorption,and permeability decrease with 1.6 per cent of initial permeability of shrinkage/swelling model based on pressure changes,and the cumulative methane production of former is 1.5 times of later,and the CO₂ injection rate and cumulative CO₂ sequestration of later is 14 and 3.85 times of former,with CO₂ injection.The results indicate that both the methane production and CO₂ sequestration are affected by matrix shrinkage/swelling,and dominated by shrinkage/swelling model which based on sorption and desorption.

Key words： Methane production; CO₂ sequestration; Matrix shrinkage and swelling; Numerical simulation.
