Analysis of the environmental-protecting drilling fluids application and development direction

This article discusses the increasingly severe environmental pollution problems on waste drillidg fluids, and the researches and applications of environmental-protecting drilling fluids in recent years. The drilling fluids include white oil base drilling fluid, alkyl glucoside drilling fluid, silicate drilling fluid,synthetic drilling fluid and JLX drilling fluid. Their effect mechanisms and suitabilities are analyzed. The additives for the environment-protecting drilling fluids developed in present years are summarized. The difficulties existing in the development of the environment-protecting drilling fluids are pointed out, and the development trend in the study of the environment-protecting drilling fluid is put forward.
