    摘要: Improved emulsifying agents for oil based drilling fluids, compared to imidazoline materials presently being used in oil based drilling fluids, that not only are excellent emulsifiers for oil based drilling fluids, but also are effective wetting agents and fluid loss control agents in invert (water-in-oil) systems, are obtained from imidazolines prepared by reacting long chain fatty acids with polyalkylene polyamines to form a 2-alkyl imidazoline, and then reacting the 2-alkyl imidazoline with an activated dicarboxylic acid to form the desired 2-alkyl imidazoline derivative.
