Abstract

Greenhouse gas (GHG) emissions have caused serious global climate change, and countries worldwide are taking steps to mitigate the greenhouse effect caused by carbon emissions. CO₂ geological storage (CGS) is emerging as a large-scale technology for reducing GHG emissions and is gradually becoming one of the most important means of mitigating the greenhouse effect. There are several problems in the implementation of this technology, among which the geomechanical problems caused by injection sequestration cannot be ignored. This article reviews the impacts and hazards of geomechanical problems caused by injection and sequestration in CGS, which can lead to risks, including changes in reservoir and caprock mechanical properties, reservoir stability, caprock closure, fault activation, and induced seismicity during CO₂ injection and sequestration. This article reviews the above studies and summarizes the research methods of CGS geomechanical problems and generation mechanisms, which can help to comprehensively understand the risks faced in the CGS process and provide references and guidance for the operation, monitoring, and research of CGS in the future.

CO2地质储层与盖层力学研究进展：方法与现状

温室气体（GHG）排放造成了严重的全球气候变化，世界各国都在采取措施缓解碳排放造成的温室效应。二氧化碳地质封存（CGS）作为一种大规模减少温室气体排放的新兴技术，逐渐成为减缓温室效应的重要手段之一。该技术在实施过程中存在一些问题，其中注入封存引起的地质力学问题不容忽视。本文综述了在 CGS 中注入封存引起的地质力学问题的影响和危害，这些问题可能导致风险，包括在二氧化碳注入封存过程中储层和盖岩力学性质的变化、储层稳定性、盖岩封闭、断层活化和诱发地震等。本文回顾了上述研究，总结了CGS地质力学问题及产生机理的研究方法，有助于全面认识CGS过程中面临的风险，为今后CGS的运行、监测和研究提供参考和指导。

期刊介绍： Greenhouse Gases: Science and Technology is a new online-only scientific journal dedicated to the management of greenhouse gases. The journal will focus on methods for carbon capture and storage (CCS), as well as utilization of carbon dioxide (CO2) as a feedstock for fuels and chemicals. GHG will also provide insight into strategies to mitigate emissions of other greenhouse gases. Significant advances will be explored in critical reviews, commentary articles and short communications of broad interest. In addition, the journal will offer analyses of relevant economic and political issues, industry developments and case studies. Greenhouse Gases: Science and Technology is an exciting new online-only journal published as a co-operative venture of the SCI (Society of Chemical Industry) and John Wiley & Sons, Ltd
