G310 Fluid Loss Control Additive for Oil Well Cementing
description1
Product Description
The aggregation of water-soluble polymer molecular chains reduces the permeability of the cement slurry filter cake. The introduction of multiple functional groups enhances resistance to high temperature and salinity.
Characteristics
G310 is a modified copolymer of low-molecular-weight amide and polyhydroxy carboxylic acid.
Temperature resistance: 30–200℃.
Salt resistance: from fresh water to saturated brine.
Water solubility: readily soluble in water.
Normal dosage: 3–6% (BWOS).
Good compatibility with other additives.
Cement compatibility: suitable for all classes of oil well cement.
Good cement slurry stability, with free fluid close to zero.
Short thickening transition time, approaching right-angle thickening.
Applicable to low-density, conventional-density, and high-density cement slurry systems.
Has a slight retarding effect; at medium and low temperatures, the thickening time can be adjusted with accelerators or early strength agents.
Technical Specification
Cement slurry formulation: G-class oil well cement; W/C ratio: 0.44; G310 dosage: 5.0% (BWOC); Water: distilled water or drinking water; Slurry density: 1.90±0.01 g/cm³.
