Rheologically controlled, pumpable, fluid aqueous preparations for use for instance as water-based drilling fluids

摘要

The invention concerns the use of lower alkoxylates, which are boundary-layer-soluble in water at room temperature, of water-insoluble alcohols of natural and/or synthetic origin to control the rheological properties, even at high temperatures, of pumpable, fluid aqueous preparations of fine particulate mineral substances of natural and/or synthetic origin, the aqueous preparations being suitable for use in particular as working fluids in the disintegration zone in soil and/or geological formations, e.g. as water-based drilling fluids.
