| description | The invention relates to the technical field of oilfield exploitation, and discloses a preparation method of a thickening tackifier for an oilfield. Double long-chain alkyl groups contained in a 4, 4-acrylamido dibenzamide quaternary ammonium salt monomer can form a spatial network structure through a self-assembly effect and a physical cross-linking effect, so that the 4, 4-acrylamido dibenzamide quaternary ammonium salt monomer has a stronger hydrophobic association effect; the viscoelasticity and the tackifying effect of the thickening tackifier are favorably improved. The biquaternary ammonium salt structure can form a unique bibetaine zwitterionic group with a sulfonic acid group of 2-acrylamido-2-methylpropanesulfonic acid, so that the thickening tackifier shows an anti-polyelectrolyte effect in an aqueous solution, and the solution property of the thickening tackifier is enhanced by a hydrophobic association effect; therefore, the thickening tackifier has higher apparent viscosity.
