Produced water isolated from the oil in oil-gas production is pumped into the injection wells after cleaning from salt deposits and mechanical impurities. In the mixture of high-mineralised produced water, salt deposits making the technological equipment and pipes useless while gathering and transportation, reduce the permeability of injection wells. Carried out experimental researches show that for each ton it is necessary to pump 100 g of KD-7 inhibitor to prevent salt deposition in the mixture of produced water. Technological processes should be performed in a closed system, and the territories contaminated with oil and produced water cleaned and equipped well.
