摘要
从干热岩特点及开发手段两方面介绍了干热岩地热资源,围绕CO2在深部储层中的超临界特性,展开了其作为压裂液和工质流体的应用研究,对比了CO2-EGS与H2O-EGS的热提取性能,阐述了国内外学者针对CO2-EGS的研究进展。二氧化碳增强型地热系统(CO2-EGS)与二氧化碳地质封存(CCUS)一体化技术具有较强的可行性,其实现将对缓解化石燃料危机、节能减排具有重要作用。
The dry hot rock geothermal resources were introduced from the aspects of dry hot rock characteristics and development methods.The supercritical characteristics of CO2 in deep reservoirs were studied,the application research of CO2 as fracturing fluid and working fluid was carried out.The heat extraction performance of CO2-EGS and H2O-EGS was compared,the research progress of CO2-EGS by domestic and foreign scholars is expounded.The integrated technology of CO2-EGS and carbon dioxide geological sequestration(CCUS)has strong feasibility and its implementation will play an important role in alleviating the fossil fuel crisis,energy conservation and emission reduction.
