G311 Fluid Loss Control Additive for Oil Well Cementing
description1
Product Description
As the aggregated molecule chain of water soluble polymer can decrease the mud cake permeability of mud slurry, Introducing multi-functional groups in polymer that enhance the ability of anti-high temperature and anti-salt. In addition, by adjusting the molecular weight, impart the fluid loss additive the performance of thickening, suspension.
Characteristics
G311 is gained by the polymerization of low molecular weight amides, carboxylic acid.
G311 is a kind of viscous liquid.
Anti-temperature range: 30℃-120℃.
Salt range: fresh to saturated water.
Filtration property: ≤100mlAPI FL.
Solubility: soluble .
Dosage: 4%-6%(BWOC).
Solubility with cement: applicable for any cement classes.
Stability: free water approach zero.
Thickening time: thickening curve approach a right-angle.
Density range: any density of cement slurry system.
It has a retarding effect, and when at medium and low temperature conditions, utilizing with the early strength agent and coagulant can adjust thickening time.
Technical Specification
The ingredients of the cement in the table are: G class cement, 1.90 g/cm3; water quality: distilled water, Dosage of G311: 5.0% (BWOC).
