Summary
OBC-51S is a polymer oil well cement fluid loss additive. It is copolymerized with AMPS/NN/HA, which has good temperature and salt resistance, 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-51S has good versatility, can be used in a variety of cement slurry systems, and has good compatibility with other additives. Based on OBC-50S, the product has improved its salt resistance and has a better salt resistance function.
OBC-51S has a wide application temperature and can resist high temperatures up to 230℃. Due to the introduction of HA, the suspension stability of the cement slurry system at high temperatures is better.
Suitable for fresh water/salt water slurry preparation.
