A process for the simplified disposal of working fluids based on W/O invert emulsions.

摘要

Flowable and pumpable multicomponent mixture contains emulsifiers and additional soluble emulsifiable and dispersible auxiliary agents. The novelty is that the use of emulsifiers, e.g. emulsifier systems, lead to temperature-controlled phase inversion at a phase inversion temperature (PIT) within the range lying at the highest limit of below the working temperature of the multicomponent mixture in the region of the geological outcrop. The water-based part of the multicomponent mixture in the region of the geological outcrop is present as dispersed (invert) phase in the closed oil phase (w/o invert emulsion), whilst the lowest limit of the temperature region facilitates the conversion of the multicomponent mixture to the o/w emulsion with a closed aqueous phase.
