The invention discloses a special lubricating oil for a compound nitrogen-hydrogen compressor, which is characterized by being prepared from the following raw materials in percentage by mass: mineral base oil BS 120? 80%, modified castor oil 12%, polyisobutylene 3%, dibutyl ester 3%, silicone oil 1.95% and nitrogen 0.05%. Raw materials are prepared according to the process steps of pre-inspection, quantification, sub-adjustment, physical inspection, joint adjustment, chemical inspection, fine adjustment, bench inspection, filtration, gas treatment, final inspection and sub-packaging. The special lubricating oil contains no elements harmful to the catalyst, has good wear resistance, water resistance, ammonia resistance and aging resistance, is easy to recover and regenerate, and has good energy-saving effect, thus solving the problem that the existing nitrogen-hydrogen compressor adopts alternative oil products.
