摘要: 为揭示CO2地质封存水-岩耦合作用机制,采用文献调研和理论分析方法介绍CO2-水-岩反应试验条件和方法、CO2作用后储层物化特性、微观结构演化和力学性质劣化特征等,提出CO2-水-岩石多场耦合作用方面的关键问题,并总结分析每个关键问题的研究进展。结果表明:CO2浸泡试验缺乏对不同相态及长期动态溶蚀作用的系统性研究,试验装置难以模拟CO2在真实储层内的运移特征;CO2-水-岩反应沉淀生成-运移-粘附机制尚未明确,导致储层孔隙结构演化与力学性质劣化的关联性研究比较薄弱;储层微观结构与宏观力学参数的实质关系尚未建立,制约了多尺度损伤演化模型的构建;储层力学性质劣化模型未充分考虑热-流-固-化-损伤多场耦合作用。

Abstract:

In order to reveal the water-rock coupling mechanism of CO2 geological storage. This study employed literature research and theoretical analysis to introduce the experimental conditions and methods for CO2-water-rock reactions, the physicochemical property changes of reservoirs after CO2 action, the evolution of microstructure, and the deterioration characteristics of mechanical properties. Key issues regarding the multi-field coupling effects of CO2-water-rock interactions were proposed, and the research progress on each key issue was summarized and analyzed. The results indicate that systematic research on the dissolution effects of CO2 in different phases and under long-term dynamic conditions is lacking in CO2 immersion tests. The experimental setups fail to accurately simulate the migration characteristics of CO2 in real reservoirs. The mechanism governing the generation, transport, and adhesion of precipitates in CO2-water-rock reactions remains unclear. This leads to limited research on the correlation between pore structure evolution and mechanical property degradation in reservoirs. Furthermore, the substantive relationship between reservoir microstructure and macroscopic mechanical parameters has not yet been established, which hinders the development of multi-scale damage evolution models. Additionally, current models for reservoir mechanical property degradation do not fully account for the multi-field coupling effects of thermal-hydrological-mechanical-chemical-damage interactions.

Key words: CO2 geological storage, CO2-water-rock, mechanical properties, damage evolution, microstructure
