FIELD: drilling.
SUBSTANCE: invention relates to water-based drilling muds; it can be used in drilling oil and gas wells, mostly in drilling salt and unstable clay rocks. The cationic inhibiting drilling mud contains, wt.%: mud powder 6-8; cationic polymer Silfok 254°C 7.3-8; potassium chloride KCl 1; inhibitor of clay-sodium acetate 3.5-4; structure-forming agent – biopolymer Bioxane 0.05-0.2; water – the rest.
EFFECT: increase in inhibiting properties of a drilling mud, and improvement of its structural-rheological indicators.
