FIELD: drilling.
SUBSTANCE: system for purification from mechanical impurities for production wells is proposed. The system includes a casing, a pressure pipeline, a submersible pump, a sand pipe, a check valve, an ejector. The discharge line is connected to a submersible pump. The desiccant pipe is connected to the discharge line above the submersible pump. In the area of connection to the pressure pipeline, an ejector is installed in the sand removal tube. A check valve is installed below the ejector. The lower end of the sand pipe is located below the lower end of the submersible pump.
EFFECT: increased reliability and service life of the system.
