FIELD: extraction of minerals.
SUBSTANCE: invention relates to the field of mining operations, namely to the boreholes production of liquid fluids, and can be used in the development of oil, gas and gas condensate fields to determine the flow of water, oil and gas. According to the method, a system is installed in the borehole consisting of length-of-the-hole sensors for measuring the acoustic signal of the borehole distributed along the length of the borehole and/or point sensors of the acoustic signal, installed with the ability to move and sources distributed along the length of the borehole, including in the completion equipment that generate acoustic waves of certain frequencies and a certain intensity, when passing through them the fluid extracted from the formation or injected into the formation. In this case, the frequencies and/or signal intensities generated by the source depend on the velocity of the fluid flow and its phase composition. According to the frequencies and/or the intensity of the acoustic signal measured with the said sensors, the distribution of the inflow in the borehole is calculated, and also its phase composition for determining the technological characteristics of the borehole.
EFFECT: technical result consists in determining the inflow characteristic over time, determining the inflow of oil, water, and/or gas in different sections of the borehole.
