Mechanism of generation and intensification of high-frequency oscillationsin fractured porous media on penetration of low-frequency seismic waves

The paper considers a nonlinear hydraulic pendulum as an effective local me chanism of absorption of seismic energy in oil-bearing beds. The dissipativ e behavior of such a pendulum Is due to a permanent liquid discharge in a f ractured porous medium under pressure in injection wells. The natural frequ ency of the pendulum likewise has a dissipative character. The self-sustain ed oscillations of this system provide a characteristic frequency of pulse effects on the liquid pumped through an oil bed. The oscillating fragments of the fractured porous medium develop a power sufficient for destroying ob literation layers composed of polar oil components. Thus, the proposed mech anism of an open thermodynamic system provides absorption of seismic waves and is a tool to gain an additional yield of oil.
