Research on 3D Seismic Exploration of Excitation Parameters of Loess Plateau Gravel Interlayer

摘要

In the region of loess yuan which containing gravel interlayer, the loess layer and gravel interlayer have a strong effect on the propagation of seismic wave, which makes the energy of seismic data collected weak, low SNR, poor resolution; How to capture high-quality raw materials for 3D seismic exploration in the region is one of the difficult problems. Based on field experiment data, the key research is the way of 3 D seismic excitation and excitation parameters selection in this area. Through the energy of the reflected signal, SNR and other attributes of analysis to determine the optimal construction parameters. The results will have certain reference significance in similar loess yuan for 3 D seismic exploration.
