Dingbowei successfully launches new product-witterionic polymer viscosity reducer for drilling fluids
Zwitterionic polymers are a class of polymers that contain both positive and negative charges within the same molecule. It is used as a viscosity reducer in drilling fluids. A certain proportion of cationic functional groups is introduced into its molecular chain. The existence of cationic groups greatly improves the ability to inhibit the dispersion and expansion of shale and can improve the...
