    摘要:

    针对CO2捕集、利用与封存(CCUS)问题,将CO2注入油藏驱油,提高原油采收率的同时封存CO2,是一种绿色经济高效的生产模式。本研究建立了油藏开采三维三相多组分数值模型,研究了开采和封存效果。结果表明,CO2能够有效降低原油粘度,大幅度提升产油速率和累积产油量。另外,开采结束时,有大量CO2封存至储层。由此可见,注入CO2的开采手段具有广阔的前景。本文的研究进一步提高了对CCUS的认识,为实现中国的碳达峰、碳中和战略目标具有重要意义。

    Abstract:

    To address the problem of CO2 utilization and storage (CCUS), injecting CO2 into reservoirs to enhance crude oil recovery while storing CO2 is a green, economical and efficient production model. In this study, a three-dimensional three-phase multi-component numerical model for reservoir extraction was developed to study the extraction and storage effects. The results show that CO2 can effectively reduce the viscosity of crude oil and significantly promote the recovery rate. The cumulative oil production at 400 d with CO2 injection is 32 times higher than that with water injection. This shows that the extraction means of CO2 injection has a promising future. The research in this paper further understands CCUS, which is of great significance for achieving China''s strategic goals of carbon peaking and carbon neutrality.
