Abstract

The swell problem is prevalent in single-channel seismic, which causes jitter in the seismic events and leads to misaligned and blurred profiles, and thus interferes or misleads geological interpretation. The problem is still not well solved because all existing swell correction methods have certain conditions of applicability. Therefore, we proposed a new method of the swell static correction based on single-beam echo sounder data. First, the basic principle of the method and the implementation steps were introduced, and then the effectiveness of the method was verified against the field data and the result were compared and analyzed with the filtering method. Finally, another type of "swell-like interference" in single-channel seismic seafloor jitter phenomenon and the application effect of the new method on the problem were discussed. Results show that the new method we proposed could effectively solve the time shift problem caused by swell in single-channel seismology, especially for the swell interference in complex seabed data; and the processing effect was good.
