FIELD: oil-and-gas production.
SUBSTANCE: invention related to boring of oil and gas wells, particularly to boring solutions. Boring solution without solid state consists of wt %: carboxymethylcellulose 0.8-1.2, tartar salt 5.0-20.0, glycol 3.0-5.0, xanthane row polymer 0.3-0.4, lubrication improver BIOLUB LVL 0.1-0.2; the rest is water.
EFFECT: creation of cold resistant highlyinhibiting composition of boring solution without solid inclusions for reservoir opening in unstable sedimentation, which has high retaining, withdrawal, lubricating and inhibiting capability.
