Abstract:

The development of CO₂ sealing up for safekeeping and CO₂ enhanced CH₄ recovery in adsorption reservoir bed is reviewed. The typical characteristics of adsorption reservoir bed，including coal bed and shale bed are analyzed. The competitive adsorption capabilities  of coal/shale rock between CO₂ and CH₄ are compared. The advantages，simulation method，and evaluation method of this technology are discussed，and its prospect is presented.
