Mini-Program for Synthetic Seismogram Generation

Synthetic seismogram generation is a technique that uses mathematical models to simulate seismic wave propagation through subsurface media. It is widely applied in petroleum exploration and seismology studies, helping geologists interpret underground structures.

Such programs typically comprise several core modules: First, the reflection coefficient calculation module determines reflection strength based on acoustic impedance contrasts between different rock layers. Second, the seismic wavelet generation module simulates source characteristics using commonly adopted Ricker wavelets or custom waveforms. Finally, the convolution operation module convolves the wavelet with the reflection coefficient series to produce the final seismic record.

During implementation, special attention must be paid to sampling rate configuration to comply with the Nyquist sampling theorem and prevent frequency aliasing. Additionally, formation absorption attenuation effects should be considered, often compensated through quality factor Q values. Advanced implementations may include random noise injection functionality to make synthetic records more representative of actual field data.

These tools are invaluable for understanding seismic wave propagation principles, validating processing algorithms, and designing observation system parameters. Developers can rapidly obtain theoretical seismic responses under different geological conditions by adjusting stratum model parameters through configurable input interfaces.
