摘　　要：二氧化碳地质封存是将CO_(2)通过工程技术手段注入到地下储层中实现CO_(2)地质封存。适合CO_(2)地质封存的地质体主要有深部咸水层、枯竭油气藏、煤储层和玄武岩体等四类地质体,目前国内外在上述地质体中已实施了示范工程。本文基于上述四类地质体中典型CO_(2)地质封存工程实例,分析了不同地质封存工程注入CO_(2)效果,阐述了封存机理、封存工艺特点及影响因素,为二氧化碳地质封存研究提供地质工程技术参考。Carbon Dioxide Geological Storage involves the injection of CO_(2)into underground reservoirs through engineering techniques to achieve geological sequestration of CO_(2).Suitable geological formations for CO_(2)storage include deep saline aquifers,depleted oil and gas reservoirs,coal seams,and basalt formations.Both domestic and international projects have implemented demonstration projects in various geological formations.This paper presents typical CO_(2)geological storage engineering cases from these four types of geological formations,analyzes the effectiveness of CO_(2)injection in different geological storage projects,and compares the storage mechanisms,technical features of the storage processes,and influencing factors.This provides geological and engineering references for the study of carbon dioxide geological storage.
