四川盆地页岩油气藏CO2地质封存潜力评估

四川盆地页岩油气藏CO2地质封存潜力评估摘要随着减排政策的提出，我国作为CO2排放大国，减排迫在眉睫。通过对多种减排技术的对比，得出CO2地质封存技术减排效益最为明显，可有效改善碳排放问题。本文在前人基础上对世界CCUS技术现状进行了梳理，同时列举了现阶段已有的CCUS集群项目，再根据有关公式对四川盆地页岩油气藏CO2封存资源量进行计算。得出影响CO2地质封存的因素较多，而且对每一项因素都很敏感，变化幅度巨大，经计算得出四川盆地页岩油气藏C02封存量约为1.429×1014t,实际封存量要大于该数值。因此，若要求得更为精确的封存量，就必须了解该地区的详细资料，为进行实际封存作业时打下坚实的理论基础。关键词：CO2封存：减排：CCUS技术：Evaluation of CO2 geological storage potential inshale oil and gas reservoirs in Sichuan BasinAbstract:With the proposal of emission reduction policies,China,as a majorCO2 emitter,emission reduction is imminent.Through the comparison ofvarious emission reduction technologies,it is concluded that CO2 geologicalstorage technology has the most obvious emission reduction benefits,whichcan effectively improve carbon emissions.Based on the predecessors,thispaper sorts out the current status of CCUS technology in the world,lists theexisting CCUS cluster projects at this stage,and then calculates the CO2storage resources of shale oil and gas reservoirs in Sichuan Basin according tothe relevant formula.It is calculated that the CO2 storage capacity of shale oiland gas reservoirs in Sichuan Basin is about 1.429x1014 t,and the actualstorage amount is greater than this value.Therefore,if more precise storagequantities are required,it is necessary to know the detailed information of thearea and lay a solid theoretical basis for actual storage operations.Key words:CO2 sequestration;Emission reduction;CCUS technology;目录摘要..2Abstract:.3第一章前言51.1研究背景及意义.51.2国外研究现状1.3国内研究现状81.4完成的工作量10第二章C02利用与地质封存102.1C02的性质.102.2C02利用方式..132.3C02地质封存.…132.3.1C02封存机理142.3.2C02地质封存影响因素16第三章四川盆地页岩储层概况….173.1四川盆地自然地理条件.…173.2四川盆地区域地质背景.183.3四川盆地页岩气资源概况183.3.1页岩气开发现状.193.3.2页岩气开发面临的问题第四章四川盆地页岩油气藏C02地质封存潜力评估….21第五章现阶段所面临的问题.26第六章展望与结论.286.1结论….286.2展望.28致谢30参考文献.31
