摘要：A chrome gel system with 13 million molecular weight and 19 million molecular weight polymer and DQ-8 cross-linking agent is dynamically gelled under different conditions of 50-mesh and 100-mesh screens under different shear rates. Concentration limit. The experiment shows that the critical concentration of 13 million molecular weight gelation is 500-700mg/L, and the critical concentration of new cross-linking agent in the system is 80mg/L-90mg/L. The system of new cross-linker is cut by steel mesh. The post-gelation time is prolonged. Between 6h-10h, after 12 days of testing, the viscosity of the chrome gel system after gelation can still remain above 1000mPa·s, and the viscosity of the ungelatinized solution drops below 10mPa·s.
