Abstract
A device for generation of resonance-pulse depression vibrations at bottom-hole area of an oil well includes a fluid-pulse device that includes an accumulator, conical plunger, besides that it includes a hydraulic system comprising a distributor and a pipeline that is connected to the mouth of a production string and fluid-pulse device. The pipeline is connected to the pump unit with tank. The fluid-pulse device additionally comprises a holding chamber, inlet branch pipe that is connected to the hydraulic system, piston that forms a movable pair with a conical plunger, and accumulators are arranged as pneumatic ones. Additionally it includes a system for control of displacement of a movable pair that includes a compressor, receiver, mechanism for piston holding that includes a pneumatic distributor connected to the holding chamber.
