Summary
OBC-31S is a polymer oil well cement fluid loss additive. It is copolymerized with AMPS, 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-31S has good versatility, can be used in a variety of cement slurry systems, and has good compatibility with other additives.
OBC-31S has a wide application temperature, high temperature resistance up to 180℃, good fluidity and stability of the cement slurry system, less free liquid, no retardation, and rapid strength development.
OBC-31S is suitable for fresh water/salt water slurry mixing.
