Abstract: High-resolution exploration is a more economic and effective way in the exploration of 500 1 000 meters' shallow strata. The resolution of strata obtained from high-resolution seismic exploration is higher than routine 2D seismic exploration. High-resolution seismic is able to distinguish the thin stratum, small structure and young tectonic feature and is irreplaceable by 2D seismic exploration. According to the long working experiences about high-resolution exploration from No. 1 Marine Geological Investigation Party, Shanghai Offshore Petroleum Bureau, this paper sums up some important technical experiences of high-resolution seismic exploration on the basis of some theories of high-resolution seismic exploration, and introduces some geological examples of application to indicate that exploring technique is an crucial factor to obtain ideal geological results.
