In this paper, polyacrylamide was used for cationic modification to synthesize XP1 2 - 1, an acidizing agent that can increase the viscosity of the acid solution and improve its high temperature resistance. The properties of the gel were determined. The laboratory evaluation and on-site trial production shows that the gelling agent has excellent thickening property and meets the acid fracturing requirements of high-temperature formations.
