Regulation of the filtration process and its control in an oil reservoir is possible only if there is a certain reserve in the productivity of production and injection wells, which is largely determined by the state of the bottomhole formation zone and its filtration characteristics. Thus, the state of the bottomhole formation zones of all wells affects the efficiency of oil field development.

The circulating valve is designed for temporary communication of the central passage of the string with the annular space when performing various technological operations for well workover. It allows you to maintain the design upward flow rate of the flushing fluid.
