PERSPECTIVE OF HYDROMINERAL RESOURCES DEVELOPMENT OF OIL-FIELDS IN URAL-POVOLZHIE

It is shown that formation and produced water of terrigenous Devonian are perspective hydromineral raw material, the reserves of which are p ractically inexhaustible. Tehnological principles and structure of com plex for formation water processing with extraction of table salt, wel l killing fluid and bromine have been elaborated. By an example of NGD U ''Irkinneft'' the evaluation of efficiency of the elaborated complex for formation water processing has been performed, which confirmed th e necessity and profitability of its construction. Annual profit, obta ined from one ton of processed formation water is equivalent to profit , obtained from one ton of produced oil.
