FIELD: oil and gas production.
SUBSTANCE: procedure consists in pulse treatment of bottomhole reservoir zone by pumping fluid into flow string installed into bore of cased oil well by means of pump arranged at wellhead. In the casing at bottomhole area there are made perforation holes. Fluid containing fibres is pumped till plugs are formed in perforation holes. When consumption drops at a value exceeding typical amplitude of fluctuation, fluid without fibres is pumped at constant pressure in the pump; pressure is bult-up gradually till rapid increase of fluid consumption.
EFFECT: due to acoustic excitation of fissure of hydraulic break of reservoir there is achieved increased efficiency of procedure for further determination of typical dimensions of fissure of hydraulic break.
