CO_(2)地质封存项目环境监测评估体系初步研究

Preliminary Study on Environmental Monitoring and Assessment System of CO_(2) Geological Storage Project

神华CO_(2)封存项目是国内首个规模较大的CO_(2)咸水层封存项目,二氧化碳封存的安全性是评判该项目能否成功的重要指标。出于对该项目安全性的进一步评价,主要采用了多种监测手段,具体包括了地下、地表以及地上等区域。然而得到的监测数据没有一定的科学根据,所以介绍了一种多维度CO_(2)地质封存项目环境监测评估体系,并通过该体系对案例进行了评估。结果表明,神华CO_(2)封存项目十分稳定安全,不存在CO_(2)封存后泄露的现象。

Shenhua CO_(2) storage project is the first large-scale CO_(2) saline water layer storage project in China,and the safety of CO_(2) storage is an important indicator to judge the success of the project.In order to further evaluate the safety of the project,a variety of monitoring methods are mainly used,including underground,surface and above ground areas.However,the monitoring data obtained have no certain scientific basis,so this paper introduces a multi-dimensional CO_(2) geological storage project environmental monitoring and assessment system,and evaluates the case through this system.The results show that Shenhua CO_(2) storage project is very stable and safe,and there is no leakage after CO_(2) storage.
