FIELD: oil and gas industry.
SUBSTANCE: invention relates to the field of oil production, in particular, to well stimulation methods. The well stimulation method include running in the source of pulsed infrasonic radiation at a logging cable to the well. The source is installed opposite the productive formation in the well perforation interval. Hydraulic impact is made. At that the source of pulsed infrasonic radiation represents a cable infrasonic hydrovibrator that includes a hollow body with a pair of pistons made of non-magnetic material and placed in its cavity. A compression spring is placed between the pistons. The body is equipped with openings placed at the body ends and in the spring area. Each piston is placed inside a coil. Hydraulic impact is made due to high-speed ejection of liquid jets from the source of pulsed infrasonic radiation when a control signal is sent from the pulse current source.
EFFECT: simplification of the method with increase in efficiency.
