摘要
为解决二氧化碳对地球环境的影响,通过水力捕集、溶解捕集和矿物碳化等机制,可将二氧化碳储藏在地下。利用地质媒介存储二氧化碳的方法有:用二氧化碳来强化油气开采;将二氧化碳注入废弃的油气田;用二氧化碳取代煤层中的甲烷;将二氧化碳注入深蓄水层;将二氧化碳存储在盐洞中。现实技术已证明这些方法的可行性。
To resolve the problem of carbon dioxide on the earth environment,by hydrodynamic trapping,solubility trapping and mineral carbonation,carbon dioxide is sequestrated in the geological media. There are several potential methods for CO2 sequestration using geological media:utilization in enhanced oil and gas recovery,injection in depleted oil and gas reservoirs,displacement of methane in coal beds,injection in deep saline aquifers,and storage in salt caverns. Modern technique has demonstrated the feasibility of these methods.
