摘要（英）：

The invention provides a secondary crosslinking, profile modification and profile control agent, and a preparation method and an application thereof. A formula of the secondary crosslinking, profile modification and profile control agent comprises, by weight, 0.3-0.5 parts of polyacrylamide, 0.08-0.12 parts of potassium dichromate, 0.15-0.20 parts of sodium hydrosulphite, 0.182-0.273 parts of resorcinol, 0.018-0.0273 parts of formaldehyde, 0.15-0.25 parts of ammonium nitrate and 100 parts of water. The 2h viscosity and 24h viscosity of the secondary crosslinking, profile modification and profile control agent at 40DEG C can reach 500-1500mPa.s and above 5000mPa.s respectively, and the viscosity loss of a gelatinized gel placed in closed water environment having a salinity of 100000ppm and a temperature of 120DEG for 15d is less than 5%.
