Amphoteric polymer viscosity reducer is mainly used for viscosity reduction and dilution of drilling fluid.Its viscosity reduction rate can reach about 90%,and its temperature resistance can reach 160℃.This series of products has good compatibility with other drilling fluid treatment agents and can be directly added to various water-based drilling fluids,which is convenient to use.
