Additives for water-based drilling fluids |
| abstract |
The use of oligoglycerol fatty acid esters, prepared from n (a) an acid component chosen fromn (a1) fatty acids of the general formula (I) nn R—COOH (I) in which R represents a saturated or unsaturated, branched or linear alkyl or alkenyl radical having 7 to 21 C atoms, and/or (a2) dicarboxylic acids and/or (a3) dimer fatty acids and/or (a4) oligomer fatty acids and/or (a5) hydroxy fatty acids withn n(b) a polyol component which is chosen from oligoglycerols or alkoxylates of oligoglycerols, as an additive in water-based drilling mud compositions for improving the lubricating action of these mud systems, is described. |
