| titleOfInvention | Shear-resistant salt-resistant fracturing fluid thickening agent |
| abstract | The invention discloses a shear-resistant salt-resistant fracturing fluid thickening agent, which is prepared by carrying out polymerization reaction on raw material monomer acrylamide and a monomer A in solvent deionized water under the action conditions of a cross-linking agent N, N' -methylene bisacrylamide and an initiator; the monomer A is one of acryloyl glycinamide, acryloyl glycine or vinyl guanamine. The initiator is ammonium persulfate or 2-hydroxy-2-methyl propyl phenyl ketone. The thickening agent is a colloidal thickening agent prepared by polymerization reaction of acrylamide and a monomer A at a heating temperature of 40-50 ℃ or under the initiation condition of ultraviolet lamp irradiation. The thickening agent disclosed by the invention effectively resists permanent damage of high-speed shearing to a system structure by introducing a stable network structure formed by reversible multiple hydrogen bond supermolecular structures, and meanwhile, the tolerance of the thickening agent to salt is improved. |
