Fluid-Loss Control Additives
High-Temperature Resistant Starch for Drilling Fluids
A fluid-loss control additive made from chemically modified natural starch, combining excellent high-temperature stability with an environmentally friendly profile. It regulates mud rheology and protects wellbore stability in high-temperature drilling, making it well suited to deep and ultra-deep oil and gas wells.
APPLICATIONS
Application scenarios
- 01High-temperature deep and ultra-deep well drilling
- 02Fluid-loss control in 4% saltwater, saturated saltwater and CaCl2-treated mud systems
- 03Operations requiring low-toxicity, environmentally acceptable additives
