PROCESS OF GENERATION OF SEISMIC WAVES

seismic prospecting, sounding of lithosphere for oil and gas, sonar countermeasures. SUBSTANCE: broadening and mutual overlapping of energy levels of microparticles of deposit take place under stressed state caused by high pressure as well as by presence of impurity inclusions. Action of weak external wave field on deposit in frequency band of anomalous dissipative absorption of energy of vibration waves leads to deviation of system from equilibrium state. Hydrocarbon deposit transfers to excited state under action of mechanical vibration which results in relaxation vibration of system as whole. Generated frequency is controlled by change of starting conditions of stressed- equilibrium state. EFFECT: enhanced authenticity of seismic prospecting, possibility of generation of cophasal elastic waves. 3 dwg, 1 tbl
