FIELD: oil and gas industry.
SUBSTANCE: water-based drilling mud is suggested with the following composition, in kg/m3: aggregating agent Base Medium B 10-40; KOH 0.05-0.3; rheology regulator component Poliksan 1.5-4.0; mud filtration regulator component Osnopak NO 0.8-3.0; rheology and filtration regulator component Osnopak VO 0.5-1.0; filtration regulator component Amilor R-122 12-30; pH regulator, swelling inhibitor - hydrated lime 2-5; swelling inhibitor - gypsum 15-18; potassium alum AlgypoDS-103 1,0-3,0; colmatant-filler UMS-100 40-200; process water - remaining volume up to 1 cubic metre, and the method for drill mud production.
EFFECT: ensuring high inhibiting and low dispersing properties of the drill mud, low water loss preventing slides and collapses, reducing moisturising properties of the mud.
