Application of a wide line and geophone continuous array seismic acquisition technique in the mountainous YingXiongling area of the Qaidam basin

The potential for economic oil and gas reservoirs in the YingXiongling(YL) area of the Qaidam basin in west China is huge. However, exploration in this region is hindered by the complex near-surface and underground conditions, resulting in very low signal-to-noise ratios of seismic data and difficulties in imaging structures. These problems can be addressed by using a wide line geometry that can improve effective folds and a multi-geophone cross-line continuous array method. The combination of these two methods effectively suppresses the side scattering interference and improves original seismic data signal-to-noise ratios and imaging quality. These methods were tested in the geologically complex and mountainous YingXiongling area and were successful at interpreting the structure. This study shows that a wide line and geophone continuous array seismic acquisition technique is an effective and feasible seismic prospecting method and could be useful for seismic prospecting in similar complex mountainous areas.
