Polyacrylamide is used as an additive for drilling fluids and can be used as the drilling mud performance modifier in the drilling process. The role of polyacrylamide is to improve the rheology of the drilling fluid, carry rock debris, lubricate the drill bit, and increase the rate of penetration. In addition, it can greatly reduce sticking accidents, reduce equipment wear, prevent well blowouts and borehole collapse, and avoid formation damage during drilling.

PHPA is short for partially hydrolyzed polyacrylamide.

Product Details

PHPA series are co-polymer of anionic character and different molecular weight water-soluble polymers, which are primarily used as a highly efficient fluid loss reducer, viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems. It is compatible with most of the drilling fluid products, biopolymers, PAC, CMC. It maintains borehole stability by preventing shale swelling and erosion.
