ZD-FR adopts the design of molecular structure. ZD-FR is polymerized with solvent method through theoptimization of monomer of salt resistance and high temperature resistance. The steric hindrance andpolymer molecular rigidity are enhanced because of reasonable space volume of the monomers. So ZD-FR overcome the disadvantages of poor shear performance, poor salt resistance, poor FLHTHPperformance of conventional polymer filtration reducer, is a new polymer filtration reducer withexcellent performance. It can be applied in deep wells, ultra-deep wells and high-salinity brine drillingfluids. The recommend dosage is 3 - 7ppb.
