Summary
OBC-30S is a polymer oil well cement fluid loss additive. It is copolymerized with AMPS/AM, which has good resistance to temperature and salt, as the main monomer, combined with other salt-tolerant monomers. The molecule contains a large number of -CONH2, -SO3H, -COOH and other strong adsorption groups, which play an important role in salt resistance, temperature resistance, free water adsorption, and fluid loss reduction.
OBC-30S has a wide application temperature, high temperature resistance up to 150°C, good fluidity and stability of the cement slurry system, less free liquid, no retardation, and rapid strength development.
OBC-30S is suitable for configuring various seawater cement slurry systems and has good compatibility with other additives.
OBC-30S has strong dispersibility in cement slurry, and is especially suitable for the configuration of cement slurry systems with high solid content in fresh water or a high proportion of ultra-fine materials.
