摘要

在介绍超临界二氧化碳特性的基础上，着重论述了scCO₂-ESGR工艺的核心技术，剖析了scCO₂强化开采页岩气的技术优越性，并指出了目前尚需解决的科学问题及存在的弊端和不足，最后提出了从室内理论研究和现场应用效果评价2方面出发，双管齐下，全面实现页岩气的高效开发和规模化生产。

Abstract

Based on introducing the characteristics of supercritical carbon dioxide, the core technology of supercritical carbon dioxide-enhanced shale gas recovery (scCO₂-ESGR) process is emphatically discussed to analyze the technical advantages of scCO₂-ESGR.The technical problems to be solved as well as the disadvantages and shortcomings are pointed out.Finally, it is proposed that the high-efficiency development and large-scale production of shale gas can be realized through indoor theoretical research and field application effect evaluation.
