FIELD: chemistry. ^ SUBSTANCE: invention relates to construction of oil and gas wells, specifically to water-based drill fluids for drilling wells. The inhibiting drill fluid contains, wt %: polyglycol 8 to 12; bentonite 2 to 3; reagent-stabiliser 0.4 to 0.9; lubricant additive 1 to 2; floatation reagent 1 to 1.5; anti-foaming agent 0.01 to 0.02; water 80 to 86; carbonate filling material - the rest, until specified density of the said solution. ^ EFFECT: improved inhibiting properties of drill fluid. ^ 1 ex |
