摘要：
In order to explore the synergistic drag reduction effect of composite system of cationic surfactant and polymer, the cationic surfactant cetyltrimethylammonium chloride (CTAC) and polymer polyacrylamide (PAM) were as the research objects. The multi-functional turbulent drag reduction experimental apparatus was designed and built, which was applied to study the effect of polymer ion type on the synergistic drag reduction of the compound system, optimize the compound system and analyze the effect of surfactant concentration/polymer concentration on the synergistic drag reduction of the compound system. The experimental results showed that synergistic drag reduction effect of different ion types PAM and CATC/NaSal compound system was presented as CPAM>AmPAM>NPAM>APAM and the CPAM-CTAC/NaSal was the optimal compound system. When the CTAC/NaSal concentration was 0.3g/L of PSP, the synergistic drag reduction effect of the CPAM-CTAC/NaSal compound system was the strongest, the DR and shear resistance reached its peak, and the average drag reduction rate was as high as 69.22%. When CTAC/NaSal increased to 0.5g/L, the average drag reduction rate quickly decreased to 10.08%, the critical generalized Reynolds number of the compound system also quickly dropped to 7535.20, and the shear resistance was weakened. As the CPAM concentration increased from 0.05g/L to 0.2g/L, the drag reduction rate in the drag reduction damage zone can increase from 9.08% to 57.49% with increasing critical generalized Reynolds number from 31272.43 to 45033.36, and the shear resistance was enhanced. When the CPAM concentration exceeded the second critical association concentration (CAC Ⅱ) 0.15g/L, the increasing trend of the drag reduction rate in the damage zone of drag reduction and shear resistance slowed down. In addition, compared with a single drag reducer, the temperature resistance of the compound system was significantly enhanced and the maximum drag reduction efficiency at 55℃ was increased to 69.05%. © 2022, Editorial Board of CIESC Journal.
