【 摘 要 】

In this paper, double cross-linked gel system was first screened. Organic chromium cross-linking agent was selected as primary cross-linking gel system, hyperbranched polyacrylamide as primary cross-linking system main polymer, phenolic resin system as a cross-linking agent for secondary cross-linked gel system, cationic polyacrylamide as a cross-linking agent for secondary cross-linked gel systems. Through the experiment, the formula of the double cross-linked gel system was that the amount of fixed hyperbranched polyacrylamide was 2000mg/L, the amount of internal network cross-linking agent was 300mg/L, the amount of stabilizer was 800mg/L, the amount of cationic polyacrylamide was 2000mg/L, the amount of enhancer was 150mg/L and the system performance was evaluated.
