Applications:
The zwitterionic polymer viscosity reducer can be directly added to various water-based drilling fluid systems, and can be used in conjunction with various drilling fluid treatment agents as a coating inhibitor. The general dosage is 0.2-0.5%.
Product Description:
The zwitterionic polymer viscosity reducer is packed in three-in-one bags, lined with polyethylene film bags, each bag has a net weight of 25Kg, and is stored in a cool, dry and ventilated place.
