Most of the boreholes are made with the use of drilling mud, which, among other things, is to remove drill cuttings from the bottom of the borehole, cool the drilling tool and reduce friction. Depending on the geological and technical conditions of the borehole, drilling fluids are used, containing various types of additives, such as: nickel, chromium, lead, iron, sulfides, chlorides, oils, phenol and lubricants. After the drilling fluid is used, it remains, together with the drill cuttings, in open reservoirs near the well. The size of such a reservoir, depending on the diameter and depth of the borehole, reaches a large surface, creating unused areas, and the toxic components of the waste cause contamination of the soil, surface and groundwater. There is a known method of partial neutralization of flushing waste by mixing it with lime or a mixture of lime and gypsum. There is also a method of neutralizing flushing waste, according to the British patent No. 1,485,625 consisting in the stepwise addition and mixing of the waste with cement, lime, aluminosilicate or aluminum silicate and fly ash. These methods, however, do not ensure the adsorption of most of the toxic compounds contained in the drilling mud waste, and moreover, the solidified waste forms a hard material, preventing its removal from earth tanks to a landfill or for further treatment by mixing with soil. according to the invention, the method of neutralizing and solidifying drilling mud waste with the addition of lime, gypsum, cement, and fly ash according to the invention consists in the fact that the previously mixed drilling mud waste, depending on its solid and liquid phase content, and their chemical composition, constantly stirring , the following components are added: fly ash containing up to 25% alumina and up to 48% calcium oxide, in an amount from 1 to 35% by weight in relation to the content of the liquid phase, 4% aqueous polyacrylamide solution, in an amount from 1 to 5 % by volume in relation to the liquid phase of the flake waste, Ca (OH) 2, FeS04x7H20, A12 (S04) 3 + Ca (OH) 2 in an amount from 0 to 10% by weight in relation to the phase liquid and gypsum, water glass, cement, urea resin in amounts from 0 to 10% by weight in relation to the liquid phase. The amount and type of components that adsorb and solidify the drilling mud waste is determined depending on the chemical composition, pH and content the solid and liquid phases in this waste. Ca (OH) 3, FeSO4x7H20, Al2 (SO4) 3 4- Ca (OH) j are added to the fly ash when the amounts of CaO, Fe2O3 and Al2Os contained in the fly ash are insufficient for adsorption. The addition of gypsum, water glass, cement, urea resin depends on the content of chromium, oils and their alkalinity in the waste. 124 516124 516 The addition of a 4% aqueous solution of polyacrylamide has a constant waste water content of 11T, which means that even freshly fresh crobial rinse wastes do not disintegrate in the water, which is particularly advantageous in the case of rainfall waste occurring during the solidification treatment. According to the invention, the advantage of neutralizing drilling mud waste is the complete adsorption of toxic additives, so that they do not pose a threat to the environment. This method also makes it possible to easily remove the solidified mass and restore the site to its original state. Example 1. For mixed drilling mud waste with a density of 1.49 g / cm3 and a pH = 9.5, consisting of a solid phase of 22% by weight, water of 74% by weight and oil of 4% by weight, and containing the composition of 82.5% mg / l chromium, 17.2% g / l iron, add, with constant stirring, fly ash in the amount of 6.8% by weight, based on the liquid phase, hydrated lime in the amount of 1.4% by weight with respect to the liquid phase, 4% aqueous polyacrylamide solution in the amount of 3% by volume, in relation to the liquid phase, and cement in the amount of 1.3%, water glass in the amount of 2.7% by weight in relation to the liquid phase. adsorption occurs after 72 hours.Example II Drilling mud beds with a density of 1.17 g / cm3 and pH = 9.2 consisting of a solid phase of 9%, water - 90% and oil in the amount of 1% by weight, and containing 0.33 mg / l phenols and 33.3 mg / l of chromium, 10.0 g / l of iron, are added with constant stirring of fly ash in an amount of 22% by weight of the liquid phase, hydrated lime in an amount of 0.6% by weight of the phase liquid building gypsum in the amount of 5.5% by weight in relation to the liquid phase and 4% in water solution of polyacrylamide in the amount of 3.3% by volume in relation to the liquid phase. Solidification and adsorption takes 2 days. Example III. For mixed drilling mud waste, a density of 1.17 g / cm3 and a pH = 9.2, consisting of a solid phase of 15% by weight, water of 83% by weight and oil 2% by weight, and containing the composition of 250 mg / l phenols, 20 mg / l chromium, 50 mg / l lead and 10 g / l iron, add, with constant stirring, 4% by weight of fly ash, based on the liquid phase, 4% water solution of polyacrylamide , 3.2% by volume in relation to the liquid phase and water glass in the amount of 5% by weight in relation to the liquid phase. Solidification and adsorption takes 14 days. Example IV. For: and mixed drilling mud waste with a density of 1.17 g / cm3 and pH = 9.2, consisting of a solid phase of 15%, water - 83% and oil 2% and containing 20 mg / l chromium, 5 250 mg / l of phenols and 10.3 g / l of iron are added, while stirring continuously, 12.5% by weight of fly ash, based on the liquid phase, and 2.5% of the hygrated lime. by weight, based on the liquid phase, and a 4% aqueous solution of polyacrylamide in the amount of 2.5% by volume and with respect to the liquid phase. Solidification of the rinsing waste takes place after 3 days; adsorption after 24 hours.
