    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.
