VERWENDUNG OBERFLAECHENAKTIVER ESTERSULFONAT-SALZE IN WASSER- UND OELBASIERTEN BOHRSPUELUNGEN UND ANDEREN BOHRLOCHBEHANDLUNGSMITTELN |
摘要 |
Described is the use of surface-active salts of internally sulphonated esters, in which most of the sulphur is organically bound, made from at least once olefinically unsaturated carboxylic acids with at least 8 C-atoms and lower monohydric and/or polyhydric alcohols (ester sulphonate salts) as environmentally compatible emulsifiers of the water-in-oil type or oil-in-water type in fluid, pumpable bore-flushing agents or other drilling fluids which have, in addition to an aqueous phase, a closed or disperse oil phase and are suitable for the non-polluting exploitation of natural deposits of e.g. oil or gas. The invention also concerns in particular invert bore-flushing agents with a closed oil phase containing a disperse aqueous phase and which contain, in addition to emulsifiers, other usual additives such as thickeners, fluid-loss additives, filling agents, water-soluble salts and alkali reserves. The invert bore-flushing agents are characterized in that they contain, in addition to an environmentally compatible closed oil phase, surface-active ester sulphonate salts of the kind stated as the emulsifier or as a component of the emulsifier.
