The present invention provides an amphiphilic macromolecule and its use. Amphiphilic macromolecules contain repetitive structural units: structural units for molecular weight control, molecular mass distribution and charge properties effects, highly sterically hindered structural units and amphiphilic structural units that are suitable for areas such as oil well drilling, well cementing, education crude oil collection and transportation, wastewater treatment, sludge processing and papermaking, etc., and can be used as e oil-displacing agent in the method of enhanced oil recovery, viscosity reducer heavy oil fracturing fluid, unstable clay stabilizer, agent for wastewater, retention aid and a drying additive or reinforcing agent for papermaking, etc. |
