A fracturing fluid comprising a proppant and an associative amphoteric polymer in an aqueous solution, the polymer comprising: ‑0.01 to 10 mol % of at least one hydrophobic chain-containing cationic monomer, ‑ 0.09 to 89.99 mol % of at least An anionic monomer, ‑ and 10 to 99.9 mol% of at least one nonionic water-soluble monomer, the total amount of ‑monomer being 100 mol%. Fracturing method using this fluid. |
