CONCENTRATE OF BIOLOGICAL BROADCASTING ADDITIVES, IMPROVED LUBRICATION PROPERTIES OF WATER-BASED DRILLING SOLUTIONS, ITS USE AND WATER-DRILLING SOLUTION FOR DRILLING

摘要

ASTM D97 biodegradable additive concentrate with a pour point less than -5 ° C improves the lubricating properties of water-based drilling fluids and contains at least one compound selected from the group consisting of diglycerol mono- and di-esters acids and derivatives of monocarboxylic fatty acid esters containing from 16 to 22 carbon atoms in the chain; acids and derivatives of esters resin acids; monoesters of polyalcohols containing more than 4 hydroxy groups, and fatty carboxylic acids containing from 6 to 12 carbon atoms, which are saturated or have at least one unsaturated bond; mono- and polyalkoxylated esters of saturated and unsaturated dicarboxylic acids containing from 6 to 12 carbon atoms. The use of this concentrate in a water-based drilling fluid and containing a concentrate of a water-based drilling fluid, suitable for use in drilling.
