A nanographene, a preparation method thereof, and uses thereof are disclosed. The method of preparing the nanographene includes the steps: (1) carrying out a first reaction by contacting a raw material graphite and a first oxidizing agent with an intercalating agent to obtain a modified graphite; (2) performing a second reaction by contacting the modified graphite and an acid with a second oxidizing agent to obtain a graphene pre-product; and (3) subjecting the graphene pre-product to an air-flow exfoliation to prepare a nanographene. An oil-based drilling fluid containing the nanographene produced by the method is also disclosed.
