G35S Fluid Loss Control Additive for Oil Well Cementing
description1
Product Description
G35S belongs to pure polymerization and water-soluble agent, reducing the slurry cake permeability by the aggregation of water-soluble high polymer molecular chain. At the same time, G35S introduces various functional groups into the polymer to improve the suspension properties of the cement slurry.
Characteristics
G35S is modified and polymerized by AMPS, low molecular amide, and Polyhydroxy carboxylic acid etc.
Temperature Range: 30~200℃.
Water solubility: soluble in water.
Generally dosage range: 0.5~1.0% (BWOC).
Good compatibility with other cementing additives.
Compatibility with cement: suitable for all classes of cement.
The cement slurry thickening transition time is short, close to right angle thickening.
Suitable for low,and conventional cement slurry system.
Excellent suspension performance in cement slurry.
Having a little retarding property to the cement slurry.
