A technology of deep seismic exploration is widely regarded by international geologists as the most skillful tool not only to survey fine structures in deeper lithosphere but also to solve geological problems appearing in deeper strata. At present, it has been widely used to study both tectonic framework of orogenic belts and fine structures of lithosphere, and to depict the Moho location and strike. Being capable of surveying deeper depth, this technology is quite different from other routine seismic technologies. The deep seismic exploration is better at large offset distance, big shooting charge, and long recording length. Its application to Sichuan Basin emphasizes on recording-geometry design and shooting-charge optimization. Moreover, some acquisition schemes and job practices suitable for deep seismic exploration are summarized.
