FIELD: oil and gas production. SUBSTANCE: exhausted drilling mud accumulated during development of oil and gas wells is treated with coagulant-flocculant, after which mixture is separated on centrifuge into liquid and solid phases, which are immediately suited to reuse. Coagulant-flocculant utilized is an organomineral combination comprising 70-97% calcium oxide, 1.0% polyglycol, 1.0% oligosaccharide, and 1-28% monosaccharide. EFFECT: reduced expenses, increased environmental safety, and improved quality of reuse. 1 dwg, 1 tbl |
