emulsion, its production process and its use, process for surface cleaning, production of a well and production of an oil or gas

摘要

The present invention relates to an emulsion, consisting of an oil phase and an aqueous phase and comprising as emulsion components (1) 15 to 40% by weight of at least one water-immiscible organic solvent as solvent of the oil phase, (2) 15 to 40% by weight of water as solvent of the aqueous phase, (3) 10 to 40% by weight of at least one surfactant, (4) 10 to 40% by weight of an alkoxylated fatty alcohol and (5) 0 to 25% by weight of at least one other additive, wherein the quantities by weight of the components (1) to (5) are each relative to the total weight of the emulsion, and together add up to 100% by weight. The invention further relates to a method for producing an emulsion, to the emulsion which can be obtained from said method, to the use of an emulsion, to a method for cleaning the surfaces of well holes, drilling devices or drillings, to a method for producing a well bore, and to a method for producing an oil or a gas.
