The invention discloses an oil-based hydrate nucleation inhibitor as well as a preparation method and application thereof. The preparation method of the inhibitor comprises the following steps: (1) heating furfural extract oil to a molten state, filling the furfural extract oil into a reaction kettle, introducing oxidizing gas, and carrying out oxidation heat treatment while stirring; (2) stopping the input of the oxidizing gas, replacing the oxidizing gas in the reaction kettle with shielding gas, and performing closed heat treatment on the material obtained in the step (1) under the shielding gas to obtain an oil-based inhibitor component; and (3) cooling the oil-based inhibitor component obtained in the step (2), placing the cooled oil-based inhibitor component in a solvent, and mixing the cooled oil-based inhibitor component with a light oil product to obtain the oil-based hydrate nucleation inhibitor. The oil-based hydrate nucleation inhibitor prepared by the method can obviously prolong the hydrate induction period and inhibit hydrate nucleation.
