Difference analysis of seismic acquisition in rainy season and dry season in MD area

MD region belongs to mountainous area and has complex near-surface conditions. Therefore, the shooting and receiving conditions in the area is poor, and the seismic data has low signal-to-noise ratio.In order to obtain high-quality raw seismic data, we carried out field acquisition in dry season and rainy season respectively. By contrasting and analyzing the single-shot records and stack profiles obtained in the two seasons, we concluded that the quality of the seismic data acquired in dry season is better. The research result provides a good reference for the follow-up of seismic data acquisition in this region and similar regions.
