摘要： 国内外大量研究和应用成果表明,向油层中注入 CO2 可以大幅度地提高原油采收率,而且可以实现 CO2 的长期地质埋存。通过开展国外 CO2 埋存及提高原油采收率现状调研,了解国外利用油藏进行 CO2 埋存及提高采收率的最新动向,用数值模拟方法系统研究了储集层、流体性质及开采方式等因素对 CO2 驱油与埋存的影响。基于典型试验区油藏参数的数值计算结果,对影响 CO2 驱油与储存系数的因素进行综合分析,确定了影响 CO2 埋存与提高石油采收率的评价指标参数,并对各影响因素进行了评价。

Abstract: The numerous researches and applied results at home and abroad indicate that injecting CO2 into reservoir may greatly enhance oil recovery (EOR) and realize the long-term and in-situ geologic storage of CO2 . This paper presents the investigation of the status of CO2 storage and related EOR abroad and the latest trend, and studies the impact of reservoir quality, fluid property and recovery process on CO2 flooding and storage using numerical simulation method. And these influenced factors are comprehensively analyzed, according to the calculated results of reservoir parameters in pilot area, followed by that the evaluating indices for influencing CO2 storage and related EOR are determined, and these factors are evaluated.

Key words: Carbon dioxide, geologic storage, sequestration, EOR, numerical simulation
