G307A Early Strength and Anti-channeling Fluid Loss Control Additive for Oil Well Cementing
description1
Product Description
G307A Early Strength and Anti-channeling Fluid Loss Control Additive is a water-soluble polymer. In cement slurry, its molecular chain bundles aggregate, thereby reducing the permeability of the filter cake. In addition, the introduction of multiple functional groups into the polymer improves its dissolution rate at low temperatures and enhances its resistance to high temperature and salinity.
Characteristics
Normal dosage: 0.9%–2.0% (BWOC).
Applicable temperature range: 30℃–120℃ (BHCT).
It features low fluid loss and is compatible with other additives.
Suitable for dry mixing.
Technical Specification
Cement slurry formulation: G-class oil well cement; W/C ratio: 0.44; G307A dosage: 1.2% (BWOC); Water: distilled water or drinking tap water; Slurry density: 1.90±0.01 g/cm³.”
