This invention discloses a method for preparing a retarder for acid fracturing. The retarder is obtained by copolymerizing a nonionic water-soluble monomer, a silicon-containing monomer, an organic acid adsorbent monomer, and a hydrophobic monomer in an anhydrous organic solvent. After the reaction, the resulting product is directly used as an additive in the working fluid without the need for separation and drying. The organic acid adsorbent monomer contains an iminodiacetic acid structure, which chelates with Ca on the surface of carbonate rocks. 2+ Stable adsorption; after hydrolysis, the silicon-containing monomers condense with hydroxyl groups on the rock surface to form chemical bonds, while the condensation and cross-linking between silicon and hydroxyl groups construct a multi-layer network structure; the hydrophobic monomer is an allyl polyoxyethylene alkyl ether, which forms a hydrophobic barrier on the adsorption film surface through hydrophobic association. The resulting retarder, through the synergistic effect of four mechanisms—chelation adsorption, chemical bonding, multi-layer film formation, and hydrophobic shielding—can reduce the acid rock reaction rate by more than 90% at 150°C and in 20% hydrochloric acid, making it suitable for high-temperature carbonate rock acid fracturing operations.
