BENTONE® 42
流变剂油基高温增黏剂
BENTONE 42 was designed to build gel strength and viscosity in synthetic-based invert emulsion drilling fluids and maintain this viscosity build through extreme temperatures. It is a specially designed organoclay which was chemically engineered to maintain product performance when subjected to temperatures as high as 450ºF for as long as 600 hours. Additionally, as temperature increases, the viscosity at temperature remains flat. This flat rheology over temperature minimizes the tendency for barite sag while improving cuttings transport and hole cleaning. BENTONE 42 exhibits an excellent balance of dispersibility with initial viscosity build, efficiency and tolerance to adverse conditions for reduced depletion rates.
