G310HS Fluid Loss Additives for Oil Well Cementing
description1
Product Description
G310HS mechanism of action: the aggregation of water-soluble polymer molecular chains reduces the permeability of the cement slurry filter cake. By introducing a variety of functional groups into the G310H polymer to enhance the high temperature and salt resistance of the product.
Characteristics
Modified by AMPS, polymerization of low molecular amide and polyhydroxy carboxylic acid.
Temperature resistance: 40~200℃.
Salt resistance: fresh water to saturated salt water.
Water solubility: easily soluble in water.
General dosage range: 0.8~2%(BWOC).
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.
It is suitable for the design of low density, conventional density and high density cement slurry system.
Technical Specification
Cement slurry formula:Grade G oil well cement, 35% quartz sand, 1.5% G310HS (BWOC), 0.3% UPV-L, 1.0% GH-8L The water quality is distilled water or drinking water, and the cement slurry density is 1.90±0.01g/cm3.
