Emulsification, Wetting & Foam Control
Polyether Defoamer for Drilling Fluids
A polyether-based defoamer built on polyether polyols, combining fast foam knockdown with long-lasting foam suppression. It tolerates high temperature and pressure, is fully compatible with drilling fluid systems, and removes foam from gas cutting and additive reactions without affecting mud rheology.
APPLICATIONS
Application scenarios
- 01Foam control in freshwater, saltwater and saturated saltwater muds
- 02Deep, ultra-deep and HTHP drilling operations
- 03Circulation systems, solids control equipment and mud mixing plants; also effective on secondary foam from polymers and surfactants
PERFORMANCE
Performance indicators
| Test Item | Specification | |||
|---|---|---|---|---|
| Test Item | Silicone Oil Type | Polyether Type | Standard Type | |
| Density Recovery Rate in Freshwater Mud % | ≥ | 95 | 90 | 85 |
| Density Recovery Rate in Saltwater Mud % | ≥ | 95 | 90 |
USAGE
Usage
Add directly at the foam-generating point of the circulation system; typical dosage is 0.05%-0.3% by weight, adjusted to foam severity. Dose in small increments to avoid overtreatment.
PACKAGING
Packaging & delivery
Supplied in plastic drums. Ship as non-hazardous goods; protect from impact, tipping, direct sunlight and freezing during transport.
