GH-3S Fluid Loss Additives for Oil Well Cementing
description1
Product Description
The molecular chain bundles of water-soluble high-molecular-weight polymers aggregate to reduce the permeability of the cement slurry filter cake. Introducing a variety of functional groups into the polymer to enhance the high temperature and salt resistance.
Characteristics
Modified by polymerization of AMPS, low molecular amide, polyhydroxy carboxylic acid, etc.
Temperature resistance: 30~150℃.
Water loss reduction performance: APIFL below 100ml.
Water solubility: easily soluble in water.
General dosage range: 1~3%(BWOS).
Good compatibility with other additives.
Compatibility with cement: suitable for all levels of oil well cement.
The cement has good stability and the free liquid is close to zero.
The thickening transition time of cement slurry is short, close to right-angle thickening.
Slightly retards to the cement slurry.
Technical Specification
Cement slurry formula: G grade oil well cement, fluid loss reducer GH-3S 1.5% (BWOC), water-cement ratio 0.44, cement slurry density 1.90±0.01g/cm3, water quality: distilled water or drinking water.
