- Abstract:
- Using the finite different method,we numerically simulate the effect of excitation factors on airgun signal in Binchuan Reservoir.The result shows that the relationship between the change of reservoir water level and airgun signal amplitude is nonlinear,there is an optimum water level range of 30～35 m for airgun firing test which can excitate the strongest energy of signal amplitude,in addition the influence of water level changing attenuates with distances.We also fit the power equation between the amplitude of water level changing and the average amplitude change rate it produced,so that we can use it to provide theoretical reference for removing the effect of water level changing in actual waveform application.The wave amplitude is linear with excitation energy and towing depth,that is the greater the energy and the deeper of the towing,the better the effect of excitation,the more conducive to detect remote and deep penetration underground structure.
