The invention provides an amphiphilic macromolecule and its use. Amphiphilic macromolecules contain repeating structural units: structural units to regulate molecular weight and molecular weight distribution and effects of charge properties, highly sterically hindered structural units and amphiphilic structural units, which are suitable for areas such as oil drilling, well cementing, formation fracturing, collection and transportation of crude oil, wastewater treatment, sludge processing and papermaking and so on, and can be applied as an oil displacing agent in enhanced oil recovery, heavy oil viscosity reducer, fracturing fluid, unstable clay stabilizer, wastewater treatment agent water, retention agent and drying agent for papermaking or hardening agent, and so on. |
