| titleOfInvention | Temperature-resistant and salt-resistant gemini amphoteric surfactant and preparation method and application thereof |
| abstract | The invention provides a temperature-resistant and salt-resistant gemini amphoteric surfactant, a preparation method and application thereof, which show a specific structural formula, and also provide a preparation method of the temperature-resistant and salt-resistant gemini amphoteric surfactant and application of the temperature-resistant and salt-resistant gemini amphoteric surfactant in clean fracturing fluid. According to the invention, sulfonate, an ultralong hydrophobic chain and cations are introduced into surfactant molecules, and then the sulfonate, the ultralong hydrophobic chain and the cations are compounded with a counter-ion salt to obtain the clean fracturing fluid, so that the clean fracturing fluid has excellent sand suspension performance, temperature resistance, shear resistance and salt tolerance, is simple to prepare on site, has low cost, can automatically break gel, has little damage to a stratum, and effectively solves the problems of poor temperature resistance, poor stability, complex composition of a fracturing fluid system, inconvenience in liquid preparation on site and the like. |
