FIELD: oil and gas industry.
SUBSTANCE: invention is related to drilling of wells. Water-based drill fluid contains cationic salt of polyamine carboxylic acids at alkali pH higher than 9.0.
EFFECT: increased bit drilling rate in carbonaceous rocks, reduced time of well-drilling, reduced corrosion of drill stem and surface of drilling equipment.
