Introduction
———

DYGJ34S is an AMPS-based, water-soluble polymer designed for oil-well cementing to deliver reliable fluid-loss control and help form a low-permeability filter cake. It is engineered to maintain performance across a wide temperature window of BHCT 30–180°C (86–356°F) and to work in challenging water chemistries from fresh water to saturated brine, supporting stable cement placement and improved slurry integrity.

Applications / Functions
—————

• Provides fluid-loss control for oil-well cement slurries

• Helps build a tight, low-permeability filter cake to reduce filtrate invasion

• Supports slurry performance in freshwater, brine, and saturated brine mixing water

• Offers broad cement compatibility for common oil-well cement systems

• Helps maintain pumpability and placement quality under demanding conditions

Advantages
———

• Wide temperature applicability: BHCT 30–180°C (86–356°F)

• Designed for salt tolerance from fresh water to saturated brine

• Compatible with a wide range of oil-well cements (lab verification recommended for specific formulations)

• Improves slurry integrity by promoting a low-permeability filter cake
