The engineering slurry viscosity reducer is mainly used in the viscosity that reduces engineering mud, regulates the rheological of engineering mud, becomes the tunnel and passes through indispensable mud conditioner in the engineering process.
Surfactants, as the main water-soluble viscosity reducers, are widely used to reduce viscosity, which can replace the active species in heavy oil to adsorb on the oil-water interface and form O/W emulsions. Yet, there are still many problems in practical application.
