Abstract：It is believed that Mesozoic-Paleozoic marine sedimentary strata in the central uplift region of the South Yellow Sea Basin is extremely thick, and it bears enormous hydrocarbon potential. There are some disadvantageous factors about seismic geology conditions, such as strong shielding layers in shallow part, intense multiples, and intricate geological structures. We adopt a new seismic acquisition approach integrating wide line acquisition with over/under sources. To enhance the penetrability of artificial seismic wave field and broaden seismic frequency band, huge volume over/under sources with low frequency are applied. Dual-streamer wide line seismic geometry is used to increase folds and suppress various noise. Our seismic data acquisited with the proposed approach shows that both data S/N and seismic imaging are obviously improved, which contains much more imformation of Mesozoic-Paleozoic strata in South Yellow Sea.
