Ultra-High-Temperature Compound Emulsifiers
Catalog NO.: AIMRSE-CHM-ADD-038 Manufacturer PN: CHM-EMU-UHT
• Thermal stability above 260°C; composite emulsifier, no need to add main and auxiliary emulsifiers separately; provides stronger gelation capacity compared to conventional emulsifiers.
Used to formulate high-performance oil-based drilling fluid systems without soil phase. Acts as a primary emulsifier and loss reducer, ensuring no free water in high-temperature, high-pressure filtrate while maintaining excellent thermal stability and contamination resistance.
As the sole emulsifier for ultra-high-temperature oil-based drilling fluid systems, this compound emulsifier demonstrates exceptional thermal resistance under extreme bottomhole temperatures. Used alone, it delivers excellent oil-in-water emulsification, effective oil wetting properties, controllable fluid loss, and overall system stability. This product requires the addition of slaked lime for saponification activation during use.

| Recommended Dosage | Usually, the addition amount is 22-35 kg/m³. Calcium hydroxide needs to be added during use, and the ratio of calcium hydroxide to the main emulsifier is 0.5:1. When the bottom hole temperature exceeds 230°C and the mud density is greater than 1.9, the addition amount can be up to 72 kg/m³, and 3-9 kg/m³ of high-temperature wetting agent needs to be added to improve the oil wetting ability of the system. |
