Thinners & Viscosity Reducers
Amphoteric Polymer Thinner for Drilling Fluids
A novel amphoteric polymer thinner that rapidly reduces apparent and plastic viscosity, improves rheology and cuts pump pressure losses, with viscosity reduction rates of 70% or more. It offers strong tolerance to salt, calcium and magnesium contamination and stays effective after hot rolling at 160 °C.
APPLICATIONS
Application scenarios
- 01Viscosity reduction in contaminated or high-solids muds
- 02Salt-gypsum and shale formations with ionic contamination
- 03High-temperature wells (performance retained after 160 °C hot rolling)
