Deep profile control is an important measure to control water and stabilize oil in high water-bearing oilfields. Deep profile control under low oil price requires gel has long gelation time and high strength after gelation. In this paper, the partially hydrolyzed polyacrylamide(HPAM) with low mass fraction was used as the gelling solution, and the amino resin was used as the crosslinking agent to study the gelation rule and its application conditions of the amino resin gel. The results show that under the catalysis of acetic acid, amino resin can be crosslinked with low mass fraction HPAM to form gel, which can be used in formation below 70 ℃ and salt content below 10 174 mg/L. The gelation time is more than 3 days, the gel strength can reach G grade or above, and the gelatin gel dehydration rate is less than 10% in 90 days, which is suitable for deep profile control.
