| titleOfInvention | Resistance reducing agent for fracturing fluid and application thereof |
| abstract | The invention relates to a fracturing fluid resistance reducing agent and application thereof, and mainly solves the problem of low resistance reducing rate in the prior art. The inventionThe fracturing fluid resistance reducing agent comprises the following components in parts by weight: (1)1 part of an alkylammonium halide surfactant; (2) 0.2-5 parts of counter ion salt; (3) 0.01-0.05 part of organic amine; wherein, the molecular general formula (I) of the quaternary ammonium salt surfactant, R 1 Is selected from C 12 ～C 26 A hydrocarbon group of R 2 、R 3 、R 4 Are all independently selected from C 1 ～C 4 Fatty group of (2), X — Is at least one of inorganic anions; the counter ion salt is selected from the structures shown in formula (II): r 5 Selected from H, C 1 ～C 4 Alkyl of (C) 1 ～C 4 N is R 5 N = 1-4; z is a sulfonate or carboxylate; y is a technical scheme of a cation which enables the formula (II) to be neutral, the problem is well solved, and the method can be used in the shale gas exploitation process. |
