THE USE OF SELECTED FATTY ALCOHOLS AND MIXTURES THEREOF WITH CARBOXYLIC ACID ESTERS AS LUBRICANT COMPONENT IN WATER-BASED DRILLING FLUIDS FOR GEOLOGICAL EXPLORATION |
摘要 |
The invention relates to the use of straight chain and/or branched fatty alcohols with at least 12 C-atoms in the molecule and/or the use of the mixtures of such fatty alcohols with carboxylic acid esters as an additive with a lubricant effect in water-based drilling fluid systems for the use thereof in soil exploration. The fatty alcohol based lubricant or lubricant systems are especially suited for use in water-based alkaline silicate drilling fluid systems, characterized in a manner known per se by relatively high pH values of the aqueous drilling fluid system. The inventive additives combine a lubricant effect with antifroth action or prevention of undesired foam formation.
