The invention discloses a temperature-resistant salt-resistant heavy oil emulsifying viscosity reducer and a preparation method thereof, wherein the molecular formula of the emulsifying viscosity reducer is defined in the specification, and n is a natural number and is more than or equal to 10 and less than or equal to 16. According to the invention, the emulsifying viscosity reducer has characteristics of simple synthesis process, small dosage, low cost and remarkable economic benefit, further has advantages of remarkable temperature resistance, strong salt resistance, strong emulsifying anddispersing capacity and high viscosity reduction rate, and can resist a temperature of more than 120 DEG C, resist calcium and magnesium ion concentration of 10000 mg/L and resist the total ion concentration of 200000 mg/L; the viscosity of heavy oil at 50 DEG C can be reduced by more than 95.0% at a dosage of 100 ppm; and the temperature-resistant salt-resistant heavy oil emulsifying viscosity reducer can be widely applied to on-site high-temperature and high-salt heavy oil recovery and transportation.
