AC863 Fluid Loss Additive
Product Description
1.AC863 fluid loss additive is a synthetic polymer which is capable of effectively reducing water loss filtering from the slurry to porous formation during cementing process.
2.Designed for lightweight cement slurry system and normal density cement slurry with dispersity.
3.Generate suspension stability on cement slurry, and the slurry’s stability is good.
4.Applicable in fresh water slurriesm, seawater slurries, and slurries containing CaCl2.
5.Used below temperature of 180℃(356℉, BHCT).
6.Compatible well with other additives.
7.AC863 series consists of L-type liquid, L-A type anti-freezing liquid, P-P type high purity powder, P-D type dry-mixed powder and P-T type dual-use powder.
