description	The invention discloses an amido sulfonate gemini surfactant, and a preparation method and application thereof. The method comprises the following steps: mixing maleic anhydride, n-hexadecanol and anhydrous sodium acetate, and heating to 85-95 DEG C to react for 2-4 h so as to obtain maleic acid monoester; heating and dissolving the maleic acid monoester, adding diethanol amine, a catalyst and a solvent after the maleic acid monoester is completely dissolved, stirring and reacting at 60-70 DEG C for 5-7 h, cooling to 10 DEG C or below, adding a mixed solution of acryloyl chloride and the solvent, heating to 55-65 DEG C, and reacting for 5-7 h to obtain an intermediate product; and adding a sodium hydrogen sulfite aqueous solution composed of sodium hydrogen sulfite and water into the intermediate product, and carrying out heat preservation reaction at 110-130 DEG C for 2-4 h to obtain the amido sulfonate gemini surfactant. The surfactant solves the problem of low crude oil recovery rate in tertiary oil recove
