The invention relates to a phosphoaluminate cement multi-component copolymerized retarder suitable for deep shale gas well cementation, and a preparation method and application thereof, belonging to the field of well cementation. The phosphoaluminate cement multi-component copolymerization retarder suitable for deep shale gas well cementation is characterized by being prepared from the following components in parts by weight: 100 parts of water, 40 to 80 parts of 2-acrylamido-2-methylpropanesulfonic acid, 30 to 80 parts of potassium humate, 30 to 80 parts of calcium lignosulphonate, 1 to 20 parts of methacrylic acid and 1 to 20 parts of acrylonitrile. 1 to 20 parts of acrylamide, and 1 to 20 parts of vinylpyrrolidone. The phosphoaluminate cement multi-component copolymer retarder suitable for deep shale gas well cementation is suitable for 40-120 DEG C and can be suitable for the field of deep shale gas well cementation, and the 48-hour strength of set cement is gt; the thickening time of cement paste prepared by using the retarder prepared by the method is adjustable, and the on-site construction requirements are met.
