THIXATROL® DW 50
适用于油基钻井液的通用型高分子高温/深水恒流变增黏剂
THIXATROL DW 50 is a unique proprietary organic polymer that generates an efficient rheological profile in synthetic based invert emulsion drilling fluids while having a minimal viscosity increase when subjected to reduced temperatures. 这种非常理想的一致流变特性可在 177℃ 的温度下保持稳定，并且还能扩展到深水钻井之外的应用。
In addition to maintaining a consistent or flat rheological profile from 40ºF through 350ºF, THIXATROL DW 50 is not toxic to marine life.
THIXATROL DW 50 exhibits an excellent balance of dispersibility for initial viscosity build, efficiency for cost effectiveness and tolerance to adverse conditions for reduced depletion rates. Control of ECD is significantly improved as compared to drilling fluids incorporating only conventional rheological additives.
主要特性
- “Flat” rheological profile from 40ºF through 350ºF for reduced low temperature viscosity build and improved ECD control for the elimination or reduction of mud losses. 35% reduction in 40ºF HSRR.
- Stable to bottom hole temperatures in excess of 350ºF
- PARCOM (Class D) / Mysid & Lepto compliant for global offshore applications
- Maintains HTHP fluid loss control
- 剪切稀释流变特性，可提高机械钻速 (ROP)
- Compatible with conventional invert emulsion drilling fluid additives and contaminants
- Builds viscosity in clay free systems or with organoclays
- Efficient hole cleaning and suspension properties for sag control
