The present invention provides a method for forming a graphene film through horizontally tiling and self-assembling graphene, including: proportionally adding toluene and alcohol into a graphene aqueous solution to be fully and uniformly mixed; then pouring the mixture into a vacuum filtration device, wherein when a solution in a filter flask forms a layered solution system with upper and lower layers, graphene is confined at an interface and tiled horizontally under a shear force at the interface to allow (002) planes of graphene to gradually become parallel to the interface, and graphene to be self-assembled to form the graphene film; and activating the suction filtration device to remove the solution, to obtain a graphene film with the (002) planes parallel to each other at a microscopic level on a filter paper.
