Product features
This product is a kind of polyacrylamide copolymer, which can maintain the stable drilling fluid performance, inhibit the shale hydration expansion and keep the drilling cuttings from dispersive, easy to remove. This series of polymers has a molecular weight of 2-8 million, and has a good coating effect on cuttings in fresh water and salt water as well as saturated salt water, with a temperature tolerance of more than 130℃.
