Research Progress on Exploitation Characteris-tics of CO2-Enhanced Geothermal Systems
摘要
Abstract
The research progress on the exploitation characteristics of CO2-enhanced geothermal systems is introduced.Hot dry rock geothermal energy is green,environmentally friendly,clean,renewable,widely dis-tributed,large in reserves,and highly stable.Exploit-ing hot dry rock geothermal energy plays an important role in alleviating the fossil energy crisis and reducing environmental pollution.Enhanced geothermal systems are an effective means of developing hot dry rock geo-thermal energy,with carbon dioxide and water being the two main fracturing fluids and heat exchange media in such systems.The geothermal recovery efficiency of CO2-enhanced geothermal systems is influenced by multiple factors,including reservoir geological condi-tions,wellbore design,and injection-production schemes.CO2-enhanced geothermal systems can also achieve carbon capture and storage,offering broad uti-lization prospects.关键词
