Synthesis and characterization of a novel high temperature resistant hydrophobic associative polymer for hydraulic fracturing
Hydraulic fracturing is a critical process in oil and gas extraction, particularly in high-temperature deep and ultra-deep reservoirs where traditional polymers like partially hydrolyzed polyacrylamide (HPAM) fail due to poor heat resistance. This study introduces a novel hydrophobic associative water-soluble polymer (HAWSP), AASN, designed to overcome HPAM’s limitations. AASN is synthesized by copolymerizing a specially designed two-tailed hydrophobic monomer (C8NC12AM) with acrylamide, acrylic acid, and 2-acrylamido-2-methylpropanesulfonic acid (AMPS), producing a polymer with excellent viscosity and thermal stability. Its unique structure, based on hydrophobic interactions among two-tailed monomers, forms a robust viscoelastic network in solution. This network is highly effective in transporting proppant during fracturing operations without the need for additional cross-linking agents, simplifying field application and reducing potential formation damage due to residue. Rheological tests show AASN maintains high viscosity and strong shear resistance at temperatures up to 140 °C. The study also examines its gel-breaking performance with different concentrations of ammonium persulfate, demonstrating easy degradation and low environmental impact after fracturing. The development of AASN significantly improves the performance of fracturing fluids and marks an important advancement in oilfield polymer technology. It offers a promising, heat-resistant alternative to current solutions, potentially transforming high-temperature hydraulic fracturing practices.
