摘　　要：大气中CO_(2)的地质储存,是目前应对全球气候变暖的重要技术手段之一。在化石能源不断的消耗下,未来二氧化碳地质储存的压力不断增加,我国地质资源丰富,不同构造与地质背景下储存的手段各不相同,拥有较高的理论储存能力,但限于盈利手段,尚未出现商业化项目。为了更好的进行二氧化碳地质储存方案的优化与设计,本论文总结了目前CO_(2)在地质储存方面的基本原理,围绕前沿科学问题与不同储存介质应用的基础方法进行了总结,并针对不同储存手段的特点进行了优劣比对,对部分CO_(2)的地质封存方式进行重新归纳分类,从而提出现阶段采用二氧化碳强化采油(CO_(2)Enhance Oil Recovery,CO_(2)-EOR)和咸水层二氧化碳储集两种较为可行的办法,以期为我国二氧化碳地质储存提供决策依据。Geological storage of CO_(2)in the atmosphere is an important technical means to deal with global warming at present.Due to the continuous consumption of fossil resources,the demand of geological storage of CO_(2)is increasing in future.China is rich in geological resources,with different means of storage under different structures and geological backgrounds.It has a high theoretical storage capacity,but limited to profit-making means,there has not been a commercial project.In order to better design the ideal solutions of the geological storage of CO_(2),this thesis summarizes the principles and applications of different kinds of CO_(2)geological storage,focuses on the frontier scientific issues and the basic methods applied in different storage media.The advantages and disadvantages of different storage methods are systematically compared,and some of the geological storage methods of CO_(2)are re-categorized.We would suggest that CO_(2)-EOR and storage of CO_(2)in brine is suitable for CO_(2)storage in China.
