FIELD: chemistry.
SUBSTANCE: group of inventions relates to treatment of water produced simultaneously in the production of oil. This method involves extraction of oil. For this purpose, steam is produced. Then, steam is introduced into a formation containing oil. After that, the mixture of water and oil is removed from the formation. Next, the produced water is extracted from the mixture of water and oil. Then, the produced water is processed to produce a distillate and a concentrate. Said distillate is used to produce an additional amount of steam for introduction into the formation. Next, a solvent and compounds or a solution containing multivalent cations are mixed with the concentrate. Then, after mixing the above substances, the precipitated solids containing one or more salts are separated from the concentrate.
EFFECT: technical result is an increase in the efficiency of treatment of produced water.
