摘要
通过分析咸水层CO_(2)地质封存过程中不同捕获机理,探究不同CO_(2)捕获机理下的封存量计算方法,在CO_(2)咸水层地质封存工程或数值模拟调研分析的基础上,探讨咸水层CO_(2)不同捕获机理封存量计算方法的应用范围。综合分析表明,容积法可应用于地质评价阶段的不同尺度地质单元的CO_(2)构造捕获封存量计算,代表了评价单元的最大封存潜力,在选取合理的工程、经济等参数基础上,可进行更高潜力级别封存量的计算;长时间尺度的CO_(2)束缚气捕获、溶解捕获、矿物捕获3种计算方法,应用范围为场地级或灌注级的某一时间点或时间段的实际封存量计算,只有依据封存工程或封存场地建立地质模型,并进行长时间尺度的数值模拟才能获得。
The different trapping mechanisms of the CO_(2)saline aquifers geological storage process were outlined and the storage capacity calculation methods of different CO_(2)trapping mechanisms were summarized.Based on the investigation and analysis on CO_(2)saline aquifer geological storage projects and numerical simulation,the application scope of the calculation method for different CO_(2)trapping mechanisms in saline aquifers is analyzed.After comprehensive analysis,the volumetric method can be applied to the calculation of CO_(2)structural trapping storage capacity of geological units of different scales in the geological evaluation stage.It represents the maximum storage potential of the evaluation unit.Based on the selection of reasonable engineering,economic and other parameters,volumetric method can be updated.Calculation of high potential level storage volumes.Based on the selection of reasonable engineering,economic and other parameters,it can calculate the higher-level storage capacity.The application scope of long-time scale storge capacity calculation,including the residual,solubility,and mineral trapping,is the actual storage capacity at a certain time or time period at the site level or perfusion level,which only be obtained by establishing a geological model based on a defined storage project or storage site and by numerical simulation over a long-time scale.
