Coated inhibitor amide cationic polymer CHM for drilling fluids

CHM is a linear macromolecular cationic polymer. This product has the ability to inhibit the coating of harmful clay in the formation; because the CHM molecular chain has both cationic groups and anionic groups, it can adsorb positive and negative ions on the surface and end faces of bentonite particles at the same time, thereby making it easier for harmful clay in the formation to be coalesced and wrapped, and controlling the solid content in the drilling fluid.
