Application Scenarios

Suitable for various drilling-fluid systems, including shale intervals and both fresh-water and salt-water mud systems.

Designed for demanding drilling and completion operations, with strong applicability in deep and ultra-deep wells.

Solutions

Polymer additives are key to maintaining stable drilling-fluid properties and safe downhole operation. The product series is designed to improve drilling and completion fluid performance through multiple rheological and protective functions.

• Rheology control and viscosity adjustment.

• Fluid-loss control and wellbore stabilization.

• Shale inhibition and cuttings encapsulation.

• Compatibility with fresh-water and salt-water drilling fluids.

• High-temperature performance for deep and ultra-deep wells.

• Dedicated grades for different drilling and completion fluid systems.

Product Overview

Product	Application	Features	Performance Summary
Encapsulant	Various mud systems; deep-well operations	Inhibition, fluid-loss control and lubricity; resistant to high temperature, Ca/Mg and high salinity.	Multi-functional polymer for stabilizing mud performance under demanding drilling conditions.
