FIELD: well drilling; drilling mud.
SUBSTANCE: thin clay drilling mud contains, in mass percent: 2.0-3.0 of bentonitic clay, 0.1-0.15 of carboxymethyl cellulose, 1.0-2.0 of starch, 1.0-5.0 of the reagent for resistivity control - propylene pentamers, 5.0-8.0 of carbonate weighting agent,0.1-0.5 of lubricating additive Lubriol W, remaining - water.
EFFECT: solution quality is improved due to increased resistivity at high temperature while positive filtration, structural-mechanical and rheological properties of solution are preserved.
