摘要
Described is the use of surface-active alkylglycoside compounds as ecologically compatible emulsi-fiers of the W/O type and O/W type, respectively, influid and pumpable drilling fluids and other fluiddrilling-hole treatment agents which comprise a con-tinuous or a dispersed oil phase together with anaqueous phase and which are suitable for an environment-ally acceptable exploitation of geological resources,for example oil or natural gas deposits.The invention further relates to inverted drillingfluids which are suitable for a non-polluting exploit-ation of geological resources and contain a continuousoil phase and, present therein, a dispersed aqueousphase together with emulsifiers, further conventionalauxiliary agents such as thickeners, fluid-loss addit-ives, weighting agents, water-soluble salts and/oralkali reserves, said inverted drilling fluids beingcharacterized in that they contain surface-active alkylglycoside compounds of formula (I) as emulsifier or asan emulsifier component together with an ecologicallycompatible continuous oil phase.
