Fluid Loss Additive AF550
Product Description
1.AF550 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.Applicable for low-to-moderate temperature oil well cementing.
3.Control fluid loss in normal density cement slurries, lightweight and high density cement slurries.
4.Used below temperature of 150℃(302℉, BHCT).
5.Applicable mixing water: from fresh water to half-saturated salt water.
6.Compatible well with other additives.
7.AF550 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.
