摘要:

CO2地质封存潜力的定量计算是前期封存选址适宜性评估和后期量化核查的重要组成部分。油气藏作为封存的优选地质体,兼具提高采收率经济效益与CO2封存环境效益。其中,具有良好圈闭结构的常规(枯竭)油气藏是经典碳封存潜力评估模型发展和应用的基础。而针对不同油藏条件、项目不同阶段场景以及充分考虑各种封存机制贡献的潜力评估模型仍需进一步更新。系统综述了油气藏CO2封存机制及封存潜力的评估方法,并对模型的发展历程与应用实践进行分析总结。在封存机制方面,油藏以构造封存、残余封存、溶解封存和矿化封存为主;气藏则依赖压力补充、竞争吸附和重力分异协同作用。该研究梳理了20种主流潜力评估模型,根据模型基本原理将其划分为考虑地质储量与采收率、考虑封存可用储层孔隙空间、原始模型改进与拓展、新角度与新方法4个阶段。目前,模型仍以构造和残余封存为出发点,仅少数量化溶解与矿化贡献;输入参数精细化与不确定性量化成发展趋势;混相压力预测、溶解度计算、矿化反应动力学和气体竞争吸附的时空间演化机制仍需进一步探究。未来需耦合地质监测数据与人工智能技术并开发轻量化评估工具,支撑场地级工程决策,推动封存潜力评估从“理论可行”迈向“工程落地”。

Abstract:

Quantitative calculation of CO2 geological storage potential is a crucial component of preliminary storage site suitability assessment and subsequent quantitative verification. Oil and gas reservoirs are preferred geological formations for CO2 storage, as they combine the economic benefits of enhanced recovery and the environmental benefits of carbon storage. Among them, conventional (depleted) oil and gas reservoirs with well-developed trap structures form the foundation for the development and application of classical carbon storage potential assessment models. However, models that account for different reservoir conditions, different project stages, and fully consider the contributions of various storage mechanisms still require further advancement. This paper systematically reviews the CO2 storage mechanisms and storage potential assessment methods for oil and gas reservoirs, and analyzes and summarizes the development history and application practices of these models. In terms of storage mechanisms, oil reservoirs mainly involve structural, residual, solubility, and mineral trapping, whereas gas reservoirs rely on the synergistic effects of pressure replenishment, competitive adsorption, and gravitational segregation. Twenty mainstream potential assessment models are categorized into four stages based on their fundamental principles: models considering geological reserves and recovery factors, models considering available reservoir pore space for storage, improved and extended models derived from the original models, and models focusing on new perspectives and localized approaches. Current models still primarily emphasize structural and residual trapping, with only a few quantifying solubility and mineralization contributions. Refinement of input parameters and uncertainty quantification have become development trends. Further research is needed on miscibility pressure prediction, solubility calculation, mineralization reaction kinetics, and the spatiotemporal evolution mechanisms of competitive gas adsorption. In the future, integrating geological monitoring data and artificial intelligence technologies and developing lightweight assessment tools will be essential to support site-level engineering decisions and advance the transition of storage potential assessment from theoretical feasibility to engineering implementation.

Key words: depleted oil and gas reservoirs, CO2-EOR (CO2-enhanced oil recovery), CO2-EGR (CO2-enhanced gas recovery), CO2 geological storage, potential assessment
