FIELD: oil production. SUBSTANCE: productive stratum is drilled. Directions of main stresses in rock are determined followed by crack initiation. Oscillation sources are placed in the wells. Vibration actions are generated in productive stratum the form of elastic oscillations first by making rock vibrating within 50 - 1500 Hz range, then within range equal to eigenfrequency during the time needed for changing compression stress for tensile stress. Concurrently solutions resulting in strength weakening are pumped in the well. Exciting voltage is supplied to them and elastic oscillations are controlled by changing exciting voltage and its frequency. EFFECT: control over state and properties of rock. 3 cl, 1 dwg
