The invention belongs to the technical field of oil-gas field development, and relates to an evaluation device for crude oil extracted by using carbon dioxide. The evaluation device comprises a reactor (1), a visual container (2), a first piston type intermediate container (3), a first injection pump (4), a second piston type intermediate container (5) and a second injection pump (6), wherein thereactor (1) is communicated with the visual container (2), and the reactor (1) is positioned above the visual container (2); the first injection pump (4), the first piston type intermediate container(3), the reactor (1), the second piston type intermediate container (5) and the second injection pump (6) are sequentially communicated. The evaluation device for the crude oil extracted by using carbon dioxide is simple to operate, light components in the crude oil can be rapidly extracted, and whether carbon dioxide extraction of the crude oil is completed or not can be conveniently observed. 本发明属于油气田开发技术领域，涉及一种二氧化碳萃取原油的
