摘要：
Substantially water-insoluble, oleophilic mono- and/or polyfunctional alcohols of natural and/or synthetic origin which have flash points of at least 80.degree. C., or corresponding solutions of mono- and/or polyhydric alcohols in ecologically acceptable water-insoluble oils as the dispersed oil phase of water-based O/W-emulsion drilling fluids, which are suitable for an environmentally-acceptable development of geological formations and which, if desired, contain insoluble, finely particulate weighting agents for the formation of water-based O/W-emulsions drilling muds and/or further additives, such as emulsifiers, fluid-loss additives, wetting agents, alkali reserves and/or auxiliary substances for the inhibition of drilled rock of high water-sensitivity.
