WA-1S Early Strength Additive for Oil Well Cement (Inorganic Salt Type)

• Moisture, % ≤ 13

• Fineness (0.315 mm residue, %) < 15

• Initial Consistency (32°C, 8.3 MPa, 10 min), Bc ≤ 30

• Ratio of Thickening Time (32°C, 8.3 MPa, 10 min) ≤ 0.5

• 6h Compressive Strength Ratio (39°C, atmospheric pressure), MPa ≥ 1.2

• 24h Compressive Strength Ratio (39°C, atmospheric pressure) ≥ 1.0

• Cement Slurry Composition: Class G Cement, WA-1S; Water: Distilled Water

Key Benefits

• Reduces thickening time and accelerates early strength development, supporting early production or well control requirements.

• Allows fine-tuning of pumpability and early sealing within the target temperature window through dosage adjustment.

• Compatible with fluid-loss control, dispersing, and stabilizing systems (subject to lab validation for each project).
