Product Description
l DOC-650S-B is a polymer oil well cement fluid loss agent. It is mainly composed of AMPS as the main monomer, combined with other salt resistant monomers, and co polymerized with humic acid. It plays an important role in salt resistance, temperature resistance, adsorption of free water, and reducing water loss.
l DOC-650S-B has good versatility and can be used in various cement slurry systems, with good compatibility with other additives.
l DOC-650S-B has a wide temperature range and can withstand high temperatures up to 230℃. Due to the introduction of humic acid, the cement slurry system has better suspension stability at high temperatures.
l DOC-650S-B can be used alone, and it works better when used in conjunction with DOC-631S/DOC-632S.
l DOC-650S-B is suitable for freshwater/saltwater slurry preparation.
