FIELD: oil-and-gas industry.
SUBSTANCE: well filter cleaning tool includes an oscillator, installed in a case, and the oscillator transportation to the bottomhole and power supply devices. Geophysical cable used for power supply. The oscillator transportation device includes an electric motor with a hydraulic propeller. The electrical motor and the oscillator installed in a hermetic case. The hydraulic propeller has two propellers, connected to the electric motor via gear mechanism, providing ability to rotate reversibly.
EFFECT: invention provides well filter cleaning and cleaning device transportation into well's horizontal section, avoid geophysics cable twisting due to device rotation.
