摘要
Pre-Tertiary reservoir in the central rise of the Southern Yellow Sea Basin (SYSB) consists of mainly Paleozoic and Mesozoic marine carbonates. It is of huge thickness, wide distribution and good hydrocarbon potential. Neogene low velocity strata with thickness less than 1000 m cover on the high velocity Pre-Tertiary carbonate and induce strong shielding effects on seismic wave propagation, and produce poor quality of seismic data. Therefore, this hampers the progress of hydrocarbon exploration. Based on regional geology and geophysical field in the southern Yellow Sea, theoretical modeling of seismic reflection amplitude with AVO and absorption attenuation was conducted, and the relationship of seismic amplitude and migration distance was gained. On the analysis of wavelet modeling for different airgun and cable sink depth, we chose the gun and stream array with fined waveform and strong penetration. A series of seismic acquisition parameters in the seismic experiment have been gained in order to get the signature of deep reflection.
