The invention provides a temperature-resistant anti-H2S/CO2 high-molecular polymer composite coating and a preparation method thereof. The composite coating comprises a bottom layer and a surface layer, wherein the bottom layer comprises a modified liquid novolac epoxy resin, a multipolar group polymer resin, a symmetric double-benzene-ring-structure polymer resin, a nano filler and the like; and the surface layer comprises a modified solid novolac epoxy resin, a multipolar group polymer resin, a symmetric double-benzene-ring-structure polymer resin, a nano filler and the like. The multipolar group polymer resin is introduced into the modified liquid novolac epoxy resin to implement deep addition reaction, thereby enhancing the chemical bond combination between the bottom layer and the protected body, and increasing the adhesive force. The double-benzene-ring-structure polymer resin further reacts with the modified liquid novolac epoxy resin and modified solid novolac epoxy resin, thereby increasing the cross
