FIELD: oil and gas extractive industry, possible use for selective cleaning of channels for perforation and processing of face-adjacent bed zone.
SUBSTANCE: device includes a shaft rigidly held on tubing pipe, in a form of a barrel with apertures in its walls, made at an angle, body and rotor with apertures in its walls, made with possible rotation. In accordance to invention, as the body of device, a section of perforated casing column is used. Rotor is equipped with rigidly held impeller and sliding bearings, while it is possible to move tubing column with device elements held on it along the body of device.
EFFECT: increased efficiency and increased reliability of device due to efficient destruction of solid precipitations, and also due to ensured high launching momentum of device and due to removal of ball bearings from the structure of the device.
