中文摘要：

二氧化碳地质储存是减少二氧化碳排放的有效技术之一,为确保储存工作的有效性、安全性和持久性,二氧化碳地质储存泄露途径和环境影响研究很有必要。作者通过对人为泄露通道、地质构造泄露通道以及跨越盖层和水力圈闭泄露通道等三类泄露途径分析,为储存区选择和储存工程实施提供了依据和保障;通过研究二氧化碳地质储存对健康、土壤、水体等因素可能造成的环境影响和风险,为二氧化碳地质储存环境与安全风险监测提供了方向和目标。

英文摘要：

CO2 geological storage is one of the most effective techniques to reduce CO2 emission. In order to guarantee the effectiveness, safety and durability, the study on leakage routes and environmental influence of CO2 geological storage as well as its safety and durability must be implemented. We analyzed the artificial leakage channels, geological structure leakage channels and leakage channels across the cover layer and hydraulic trap, to ensure the storage area selection and storage technique. The analysis of possible environmental impact and risk factors of storage on health, soil and water provides the direction and objective of risk monitoring for CO2 geological storage.
