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 property, so as to get better performance of carrying drilling cuttings and preventing clay flocculation. This series of polymers has a molecular weight of 2 to 6 million, and has a good viscosification effect in fresh water and salt water as well as saturated salt water, with a temperature tolerance above 150℃.

Method of application：
The amount added is adjusted according to the site conditions to obtain the desired drilling mud viscosity. The amount added is generally 0.1-0.4% in clear water and 0.4-1% in saturated brine. It is recommended to prepare 1-2% aqueous polymer solution before adding to drilling fluid as needed.
Store the product in a dry and cool place to avoid exposure to the sun. Shelf life is two years.
