Facilitating the disposal of flowable and pumpable invert emulsions

摘要

Process for facilitating the disposable of flowable and pumpable working materials based on W/O invert emulsions contg. emulsifiers, esp. corresponding auxiliary agents, from the field of exploratory drilling of the earth, and for facilitating the cleaning of contaminated solid surfaces also using flowable rinsing aids is claimed. The novelty is that by selecting and adapting the emulsifier/emulsifier system to the oil phase of the invert emulsion, a temperature-controlled phase inversion in the temperature region below the operating temperature of the W/O invert emulsions, but above the solidification temperature of the aq. phase in the temperature region of the phase inversion is ensured by solidification, and waste disposal or cleaning is carried out in the temperature range of the phase inversion and at temperature below it.
