Summary
OBF-FLC18 is synthesized from acrylamide (AM), acrylic acid (AA), sulfonic acid (AOBS), epichlorohydrin and a new ring structure of cationic monomer under the effect of the initiator through many multi-step polymerizations. It can increase the viscosity effectively in freshwater muds and increase the viscosity slightly in saltwater muds, reduce the filtration loss, improve the quality of mud cake, inhibit clay dispersion. OBF-FLC18 is suitable for seawater drilling fluids, deep well and ultra-deep well drilling fluids.
