    摘要： The invention relates to mixtures comprising acetals and oleophilic alcohols and/or oleophilic esters which are suitable for the preparation of inverted emulsion drilling muds and emulsion drilling muds. They completely or partly replace here the base oils, diesel oil, purified diesel oil, white oil, olefins and alkylbenzenes known to date. The invention furthermore relates to the use of the inverted emulsion drilling mud and emulsion drilling mud as claimed in claim 10.
