The invention relates to a method for increasing liquid hydrocarbon flushing resistance performance of polyether synthetic oil, which is characterized in that the content of hydrophilic monomer ethylene oxide in polyether of base oil can be increased, the anti-flushing capability of liquid hydrocarbon of polyether is increased; the polyether is copolymerized by ethylene oxide and epoxypropane or/and epoxybutane or/and tetrahydrofuran or/ and a long chain alpha-alkene oxide; in the polyether, ethylene oxide accounts for 20-75% according to weight ratio. The method for increasing liquid hydrocarbon flushing resistance performance of polyether synthetic oil is characterized in that proportion of ethylene oxide in polyether is added, the polyether synthetic oil has strong liquid hydrocarbon flushing resistance performance, the service life of the oil product can be prolonged, and the usage requirement of a hydrocarbons gas compressor can be ensured.
