摘要

驱油封存项目兼有提高石油采收率和封存CO

的双重效益，是目前最有经济活力的碳封存形式。然而，驱油封存项目通常含有多个井场，这些井场由于井筒的高CO

泄漏风险导致对区域有较大的安全和环境影响。针对以往基于井场点源泄漏大气扩散研究的不足，建立了一种基于井场面源通量监测的驱油封存项目地表泄漏大气CO

扩散研究方法。基于情景分析的华东某油田案例应用表明：采用基于涡度相关法的CO

泄漏通量监测可以获得整个井场的面源泄漏通量，为大范围CFD（计算流体力学）的模拟提供准确数据；多井场的CFD扩散模拟能够反映区域复杂的地形和多井场的泄漏，支撑来自井场泄漏的区域安全和环境风险管理。

Abstract

enhanced oil recovery（EOR） with carbon capture and storage（CCS） projects offer dual benefits of increasing oil recovery and CO

storage

making it one of the most economically viable carbon sequestration methods nowadays. However

EOR-CCS projects typically involve multiple well sites

and the high risk of CO

leakage from wellbores poses significant safety and environmental challenges over large areas. To address the limitations of previous atmospheric diffusion studies based on point-source leakage at well sites

a new method for studying surface CO

leakage and atmospheric diffusion in EOR-CC

S projects based on area-source flux monitoring at well sites was developed. A case study of an oilfield in East China

based on scenario analysis

demonstrated that CO

leakage flux monitoring using the eddy covariance method could provide accurate data on area-source leakage fluxes for entire well sites

enabling large-scale computational fluid dynamics（CFD） simulations. Multi-well-site CFD diffusion simulations effectively captured the impact of complex regional topography and multiple well sites on CO

leakage

supporting regional safety and environmental risk management for well site leakage.
