WF-2L Liquid Fluid-Loss Additive for Oilwell Cement (Acrylamide Type)

• Target Performance: API fluid loss (80 °C, 6.9 MPa) ≤150 mL; initial consistency ≤30 Bc; thickening linear mutation ≤10 Bc; 24 h compressive strength (130 °C, 20.7 MPa) ≥14 MPa; free water (90 °C) ≤1.4%.

• Standards Basis: SY/T 5504.2–2013 (fluid-loss additives).

• Applicable Wells: medium-to-high-temperature cementing systems (typical window: 80–130 °C, subject to project testing).

Key Benefits

• Reduces API fluid loss without significantly increasing consistency, improving annular displacement and bond quality.

• Compatible with Class G cement, silica fume, and quartz sand systems; can work with dispersants, retarders, and defoamers for rheology optimization.

• Liquid form allows easy blending and dosage control, enhancing operational repeatability on-site.
