Water - based mud thickens

Product features

This product is a kind of polyacrylamide copolymer, which can improve the viscosity and shear force of water-based drilling mud, and make it have appropriate rheological properties, so as to obtain better performance of carrying drilling cuttings and preventing clay flocculation. This series of polymer molecular weight in 5-16 million, in fresh water and salt water and saturated salt water has a good viscosity effect, temperature above 150℃.

Method of application

The dosage is adjusted according to site conditions to obtain the desired drilling mud viscosity. The dosage is generally 0.1-0.4% in clear water and 0.4-1% in saturated brine. It is recommended that 1-2% polymer solution be prepared and then added to drilling fluid as required.

Store the product in dry and cool place, avoid insolation. Shelf life is two years.
