摘要: 针对加拿大Surmont区块稠油开发过程中CO2排放量高的问题,通过构建多相组分热力耦合模型,提出稠油油藏开发阶段CO2就地消纳与封存方法,运用数值模拟方法,系统评估蒸汽辅助重力泄油(SAGD)、溶剂辅助重力泄油(ES-SAGD)与溶剂驱(VAPEX)3种技术的采收率与封存潜力。研究表明:ES-SAGD技术原油采收率可达58%,碳强度控制在0.25,展现出“双优”优势;VAPEX技术具备最低碳强度与最高溶剂回收率。模型采用实验测得的相平衡系数,并在Surmont区块进行拟合验证,具备良好的适应性与推广价值。该研究建立了“稠油开发-溶剂回收-就地封存”一体化技术,可为稠油开发后期构建低碳、高效、可持续的开发模式提供理论支撑与策略依据。

Abstract: To address the high CO2 emissions during heavy oil development in Canada′s Surmont Block, this study establishes a multiphase compositional thermal coupling model and proposes a method for in-situ CO2 utilization and storage in post-heavy-oil reservoir development. Numerical simulations were employed to systematically evaluate the production performance and storage potential of three technologies: SAGD, ES-SAGD, and VAPEX.The recovery rate of crude oil by ES-SAGD technology can reach 58%,carbon intensity is antrolled at 0.25, demonstrating dual advantages. VAPEX exhibits the lowest carbon intensity and the highest solvent recovery rate. This research establishes a synergistic pathway of "oil displacement - solvent recovery - carbon storage," providing theoretical and strategic support for constructing a low-carbon, high-efficiency, and sustainable development system in post-heavy-oil reservoir stages.
