The invention relates to a production method of fire-resistant oil applied to nuclear power station lubricating oil. The production method comprises the following steps: S1, esterification; S2, refining of base oil; s2.2, carrying out mixing and blending; s2.3, performing blending; the high-pressure fire-resistant oil provided by the invention has the characteristics of low chlorine content, low acid value, high natural point and ignition point, low free phenol, short air release value and high viscosity, and has the advantages of good lubricity, wear resistance, aging resistance, foam resistance, flame resistance, thermal oxidation stability and hydrolytic stability. The purpose of replacing imported fire-resistant oil can be completely achieved, a system or equipment using the fire-resistant oil in a nuclear power station lubricating oil system is recommended to be used, and the oil can also be applied to a steam turbine DEH system in the electric power industry to be used as control oil. 一种应用于核电站润滑油的抗燃油生产方
