摘要:
The invention describes pumpable and flowable multicomponent mixtures based on multiphased mixture of water and oil, containing emulsifiers and possibly other emulsifiable and/or dispersible auxiliary agents for use in soil decomposition through drilling and/or further processing of such exploratory drillings. The invention is characterized by the use of emulsifiers or emulsifier systems, which lead to a temperature controlled phase inversion for each multicomponent mixture concerned at a phase inversion temperature (PIT) within a temperature range whose upper limit is below the working temperature of the multicomponent mixture in the area of geological decomposition. As a result the aqueous portion of the multicomponent mixture is provided as a dispersed (invert) phase in the closed oil phase (W/O invert emulsion) while the lower limit of this temperature range enables the multicomponent mixture to be converted into and O/W emulsion with a closed aqueous phase. Emulsifiers or an emulsifier system with a PIT
