摘　　要：针对CO_(2)捕集、利用与封存(CCUS)问题,将CO_(2)注入油藏驱油,提高原油采收率的同时封存CO_(2),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,CO_(2)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CO_(2)封存至储层。由此可见,注入CO_(2)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。To address the problem of CO_(2)utilization and storage(CCUS),injecting CO_(2)into reservoirs to enhance crude oil recovery while storing CO_(2)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 CO_(2)can effectively reduce the viscosity of crude oil and significantly promote the recovery rate.The cumulative oil production at 400 d with CO_(2)injection is 32 times higher than that with water injection.This shows that the extraction means of CO_(2)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.
