    摘要： The present invention relates to an emulsion, consisting of an oil phase and an aqueous phase and comprising as emulsion components (α1) 15 to 40% by weight of at least one water-immiscible organic solvent as solvent of the oil phase, (α2) 15 to 40% by weight of water as solvent of the aqueous phase, (α3) 10 to 40% by weight of at least one surfactant, (α4) 10 to 40% by weight of an alkoxylated fatty alcohol and (α5) 0 to 25% by weight of at least one other additive, wherein the quantities by weight of the components (α1) to (α5) 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.

    摘要翻译： 本发明涉及由油相和水相组成的乳液，其包含作为油相溶剂的至少一种与水不溶混的有机溶剂15〜40重量％的乳液成分（α1）（α2） 15〜40重量％作为水相溶剂的水，（α3）10〜40重量％的至少一种表面活性剂（α4）10〜40重量％的烷氧基化脂肪醇和（α5）0〜 25重量％的至少一种其它添加剂，其中组分（α1）至（α5）的重量份数相对于乳液的总重量，并且一起加到100重量％。 本发明还涉及一种用于生产乳液的方法，可以从所述方法获得的乳液，使用乳液，用于清洁井孔，钻孔装置或钻孔的表面的方法， 生产井眼，以及生产油或气体的方法。
