To investigate the effect of chemical composition a metal–organic crosslinker on performances fracturing fluid in high-temperature conditions, four zirconium (Zr) crosslinkers and one aluminum–zirconium (Al-Zr) with polyacrylamide were used. The possessed same Zr concentration, but they differed component amounts order addition components, leading to different compositions crosslinkers. fluids prepared by tested compared terms properties rheological behavior, sand-carrying ability, microstructure, gel breaking characteristics. results showed that lactic acid, ethanediamine, sorbitol offered slowest viscosity development highest final acid ethanediamine crosslinker. sorbitol, exhibited faster crosslinking rate higher than crosslinker; density reactivity, resulting more sites strength fluid. Al-Zr-based better temperature shear resistance, viscoelasticity, recovery, ability Zr-based due synergistic aluminum ions. tertiary release gelation mechanism achieved resistance performance form continuous crosslinking, avoiding excessive dehydration reducing loss caused early damage. These indicated important factors determining fluids. Therefore, appropriate type could save costs without adding additional components required for reservoirs.

ABSTRACT In this study, a novel quaternary thickener (S−D−HPAM) for low−damage fracturing was successfully synthesized by using acrylic acid (AA) and acrylamide (AM) as the copolymer backbone synchronously introducing octadecyldimethylallyl ammonium chloride (DMCAAC−18) methacryloyloxyethylsulfobetaine (SBMA) bifunctionalized monomer. The structure of S−D−HPAM has been confirmed Fourier transform infrared spectroscopy, hydrogen nuclear magnetic resonance, thermogravimetric analysis, scanning electron microscopy, matrix−assisted laser desorption−ionization−time−of−flight mass spectrometry. Compared with hydrolyzed polyacrylamide (HPAM) directly polymerized AA AM, exhibited superior performance in terms thickening ability, salt tolerance, temperature resistance, shear sand−suspending capability, degradation. Specifically, introduction long−chain alkyl groups DMCAAC−18 could generate dynamic reversible hydrophobic interactions between polymer main chains, resulting an apparent viscosity 471.5 mPa·s solution at 3500 mg/L, which about 1.7 times higher than that HPAM (282.5 mPa∙s) same concentration. addition, hydrolysis ester bonds SBMA led to shedding sulfonic group (−SO 3 − ) from S−D−HPAM, enhanced degradation rate (83.10%) 21.81% compared (61.29%). Moreover, can synergistically form strong hydration layer reduce adsorption retention on core surface, results permeability recovery 91% low damage (8.60%) were better those (88% 11.64%). Thus, strategy dual monomers enables simultaneously improve ability reservoir. Meaningfully, technical bottleneck traditional thickeners, inevitably increase expense damaging reservoir, be effectively broken through. successful synthesis into opens new prospect development more agents.
