Introduction
———

DYJN-27 is an amphoteric polymer thinner / dispersant for water-based drilling fluids (WBM). It is designed to deliver efficient viscosity reduction while helping inhibit hydration and dispersion of reactive shale, supporting more stable rheology in challenging intervals. DYJN-27 maintains thinning performance under high temperature up to 180°C (356°F) and high salinity, and can be added directly to most WBM systems to help build and maintain non-dispersed polymer muds.

Applications / Functions
—————

• Reduces viscosity and improves flow behavior in WBM

• Helps control clay hydration / shale dispersion, improving fluid stability

• Supports formulation and maintenance of non-dispersed polymer drilling fluids

• Helps improve solids tolerance and overall rheology control in high-salinity systems

Advantages
———

• Strong thinning efficiency for viscosity control and easier hydraulics management

• HT/HS capable: designed for high salinity and temperatures up to 180°C (356°F)

• Helps reduce risks related to clay dispersion and unstable rheology

• Practical field handling: direct addition with standard mixing procedures
