摘要
The description relates to the use of at least largely water-insoluble ethers of mono and/or polyfunctional natural or synthetic alcohols which are liquid and/or at least plastically deformable at working temperature and have flash-points of at least 80 DEG C, or corresponding solutions of such ethers in ecologically acceptable water-insoluble oils as the dispersed oil phase of water-based O/W emulsion drilling fluids which are suitable for the environmentally acceptable exploitation of geological formations and may, if desired, contain insoluble, finely divided fillers for producing water-based O/W emulsion drilling muds and/or further additives like emulsifiers, fluid-loss additives, wetting agents, alkaline reserves and/or aids for the inhibition of highly water-sensitive drilled rock.
