Summary
OBC-33S is a polymer oil well cement fluid loss additive. It is copolymerized with AMPS/NN, which has good resistance to temperature and salt, as the main monomer, combined with other salt-tolerant monomers. The product introduces groups that are not easily hydrolyzed, the high temperature resistance is significantly enhanced, and the molecule contains a large number of strong adsorption groups such as -CONH2, -SO3H, -COOH, etc., which play an important role in salt resistance, temperature resistance, free water adsorption, fluid loss reduction, etc.
OBC-33S has good versatility, can be used in a variety of cement slurry systems, and has good compatibility with other additives.
OBC-33S has a high low shear rate viscosity, which can effectively enhance the suspension stability of the cement slurry system, while maintaining the fluidity of the slurry, preventing sedimentation, and having good gas channeling resistance.
OBC-33S has a wide application temperature, high temperature resistance up to 230℃, good fluidity and stability of the cement slurry system, less free liquid, no retardation, and rapid development of early strength at low temperature.
OBC-33S is suitable for fresh water/salt water slurry mixing.
