Use: challenge the flow of oil from the reservoir in the oil industry. Objective: improving the effectiveness of the impact on the productive reservoir of the well. The essence of the invention: the call of multiple pulses of depression of the fluid due to fluctuations in the volume of the peripheral zone of the borehole cavity, the accompaniment of each pulse of depression shock mechanical load and the increase in this level of total depression in the productive zone. A device for implementing the rotary type method with cameras of variable volume. Each chamber, depending on the nature of the planned impact on the productive collector, communicates with the peripheral zone and / or with the packer space: a) to create a pulse of liquid depression, the chamber for pumping liquid in communication systems with the zone and space is equipped with inlet and outlet valves, respectively; b) to trigger a hydraulic pulse, another camera is only connected with the zone (without a valve in the communication system); c) for a pause between pulses, the camera communicates only with space (without a valve in the communication system). Shock mechanical load is produced by the brisk interacting with the cam mounted on the axis of the rotor.
