SILICONE EMULSIFIER COMPOSITION INVERT EMULSIONS THEREFROM AND METHOD THEREFOR |
摘要 |
<p>An improved silicone emulsifier composition is disclosed which is particularly useful for preparing thermally stable, solids-free invert emulsions for the deep well-drilling art. The emulsifier composition comprises a surface active polydiorganosiloxane bearing one or more polyoxyalkylene radicals and one or more hydrocarbon radicals having from 6 to 18 carbon atoms and a resin component comprising (CH3)3SiO1/2 siloxane units and SiO4/2 siloxane units. Improved invert emulsions and a method for their preparation are also disclosed. The invert emulsions comprise the improved silicone emulsifier of this invention as well as a brine discontinuous phase and a liquid hydrocarbon continuous phase.</p> |
