DSP-1 is polymerized with solvent method through the optimization of monomer of salt resistance and high temperature resistance. it is a new polymer filtration reducer with excellent performance.
Sulfonate Copolymer adopts the design of molecular structure. DSP-1 is polymerized with solvent method through the optimization of monomer of salt resistance and high temperature resistance. The steric hindrance and polymer molecular rigidity are enhanced because of reasonable space volume of the monomers. So DSP-1 overcome the disadvantages of poor shear performance, poor salt resistance, poor FLHTHP performance of conventional polymer filtration reducer, is a new polymer filtration reducer with excellent performance.
White or light yellow powder
Residue (0.90mm), %
30% salt water mud
after 180℃/16h aging
It can be applied in deep wells, ultra-deep wells and high-salinity brine drilling fluids. The recommend dosage is 3 - 7ppb.
Perform well up to 200℃, can be used for deep and ultra-deep wells.
Resist salt up to saturation and resist calcium up to 10,000 ppm, so it can be applied in freshwater, saltwater, saturated saltwater and seawater drilling and completion fluids.
Decrease FLHTHP effectively, improve mud cake quality.
Shows a certain degree of inhibiting clay from hydrating.
