Hydrophobic associated polymer is widely used as fracturing fluids, but its cost is often higher than natural polymers. In order to reduce the cost, quaternary polymer AM/AA/NVP/MAO-12DAM (AANM) was successfully synthesized. The incorporation of N-vinyl-2-pyrrolidone (NVP) improves the temperature resistance of the polymer solution. Rheological and viscoelasticity test results showed that fluids with a lower dosage of AANM in the absence of any crosslinker had better performances than Guar gum (GG) with a crosslinker. Therefore, AANM is expected to be a more economical fracturing fluid thickener than GG.
