Study on the applicability of node instruments in the Southwest region of Songliao Basin

With the development and innovation of seismic exploration technology and geophysical equipment, node instruments have been rapidly promoted and popularized in the field of seismic exploration due to their lightweight, durable, flexible deployment, and independent collection and distribution recording working mode. In order to verify its applicability and effectiveness in the Southwest region of the Songliao Basin, this study compared the seismic single shot and stacked profiles obtained by Sercel 428XL wired instrument and SmartSolo node instrument under the same excitation mode through an experimental system. The experimental results showed that the seismic data collected by the two instruments are basically the same in waveform characteristics, frequency spectrum, energy, phase, first arrival, and profile imaging accuracy. The two types of data have good consistency, and it is feasible to use node instruments for data acquisition in the Southwest region of the Songliao Basin.
