摘要: 2010—2012年,中国地质调查局水文地质环境地质调查中心承担完成的“全国二氧化碳地质储存潜力评价与示范工程计划项目”,全面建立了我国二氧化碳地质储存潜力与适宜性评价指标体系与评价技术方法,评价了主要沉积盆地的二氧化碳地质储存潜力与适宜性,完成了全国1∶500万评价图系和主要盆地评价图集编制,圈定出一批二氧化碳地质储存目标靶区;构建了深部咸水层二氧化碳地质储存工程选址、场地勘查与评价技术方法;与神华集团合作,在内蒙古鄂尔多斯市伊金霍洛旗成功实施了我国首个深部咸水层二氧化碳地质储存示范工程,基本形成了我国二氧化碳地质储存基本理论和技术方法体系。Abstract: From 2010 to 2012,Center for Hydrogeology and Environmental Geology Survey,China Geological Survey launched a project“CO2 geological storage potential and suitability evaluation and demonstration project in China”.In this project,basing on the geological condition in China,we have established evaluation index system and technical methods of CO2 geological storage potential and suitability.The CO2 geological storage potential and suitability of main basins have been evaluated;series of 1∶5 000 000 regional maps and atlas of main sedimentary basin in China have been compiled;potential targets area for CO2 storage have been delineated;techniques and methods of site selection,exploration and evaluation on CO2 geological storage in deep saline aquifers have been established.Furthermore,cooperating with Shenhua Group,we have successfully launched the first coal-based CO2 geological storage demonstration project in deep saline aquifers in Ejin Horo County of Ordos City within Inner Mongolia Autonomous Region.On these bases,the preliminary basic theories,techniques and methods of CO2 geological storage potential and suitability evaluation in China have been established.
