Abstract
Drilling of wells is connected with formation of the bore mud represented by the drill cutting with waste drilling mud. Bore mud has negative physical-chemical, physical and chemical properties: high content of salts, increased alkalinity, ash structure, soil overcrust, low airing, weak filterability and so on. In case of phosphogypsum adding to the bore mud, pH level decreases from the alkaline (10.5 U) to weakly alkaline 7.6 U, decrease of pH is connected with the influence of phosphogypsum acidity and neutralization of the more mud. Concentration of chloride ions and sulphate ions in reclaimed bore mud was 70±7 and 456±46 correspondingly. Presence of oil products in received soil was 198.0-219.0 mg/kg. When adding phosphogypsum, sand, sorbent and humic formulation «Rostok» to the bore mud, it has shown good germinating ability of cultures- phytomeliorants (93,3%). 100% germinating ability was observed in meadow grass with a height of overground sprouts 10.7 cm, germinating ability of red fescue was 80% with height of overground sprouts 9.6 cm.
