Thickener (Z)-N-{3-[bis(2-hydroxyethyl)amino]propyl}docos-13-enamide (UC22-OH) for fracturing was synthesized from acrylonitrile, diethanolamine and erucic acid. Its chemical structure was characterized by 1H NMR, 13C NMR and HPLC-MS, which proves that the product was consistent with the target product. The effect of temperature on the apparent viscosity of fracturing fluid was studied, and the type and size of micelle aggregates at high temperature were analyzed. The rheology, sand-carrying, gel breaking and formation damage performance of the UC22-OH system were evaluated. The results showed that the clean fracturing fluid system was with a mass fraction of 4% UC22-OH, its apparent viscosity maintains 65 mPa·s under a shear rate of 170 s-1 at 120 ℃ for 1.5 h, indicating that UC22-OH clean fracturing fluid has excellent temperature resistance and shear resistance performance. At 80 ℃, the values of the elastic and viscous modulus (G' and G'') of the clean fracturing fluid system are >4.2 Pa and >1.7 Pa respectively. When the sand content is 20%, it can stably suspend sand within 2 h at 80 ℃. The system was completely broken within 70 minutes after encountering kerosene, and the surface interfacial tension value of the micelle-breaking fluid is low, which shows that the fracturing fluid system has excellent sand-carrying performance and micelle-breaking flowback performance at 80 °C; In the formation damage evaluation experiment, comparing the three fracturing fluid systems, the UC22-OH fracturing fluid system had the lowest permeability damage rate, only 9.1%. By comparing various performance indexes of fracturing fluid, it was found that UC22-OH clean fracturing fluid had the advantages of high temperature resistance, low residue, low damage, stable sand carrying, and easy flow interruption.
