Application
XY-27 Amphoteric Polymer can be directly added into various water-base drilling fluids and its recommended dosage is 0.35-1.75 ppb.
Advantages
Reduce the viscosity effectively.
Perform well up to 180℃, so it can be applied in deep wells and ultra-deep wells.
Resist salt contamination, so it can be applied in various freshwater, saltwater, saturated saltwater and seawater drilling fluids.
Inhibit shale dispersing, so it can be applied to build and maintain non-dispersed polymer drilling fluids.
Package and Storage
They shall be packaged in 25kg multi-wall paper sacks. They shall be stored in a shady, dry, and ventilated place.
Safety
They shall be avoided contact with eyes, skins and clothes, otherwise flush it with water. Handling methods and dangerous data shall be referred to MSDS.
