The Assessment of the Level of Pollution of Slime Pits with Heavy Metals

Abstract In drilling and running oil and gas wells the great amount of toxic waste is formed and in the surface of the lithosphere and hydrosphere the great amount of different chemical elements and compounds access, they are needed to be isolated from the environment. The most useful way of isolation is their utilization in the slime pits on the wells territory. Heavy metals are dangerous waste in the drilling slime; they accumulate in soil and under some conditions they in form water-soluble parts and migrate in to the soil. The aim of this paper is to organize the chemical and analytical research of the amount of heavy metals in the drilling slime, and research the mechanism of their spreading on different depth and square in the slime pits typical for the oil site placed in KHANTY-Ugra.
