Abstract：Tainan gas field is Quaternary biogenetic gas,having characters of shallow buried depth,thicker gas-bearing bed and simple structure,which is of benefit to use seismic data to identify gas reservoir.Because the former seismic data in that area are common-processed seismic sections that have lower S/N ratio and poorer event continuity and any feature of gas-bearing bed has not been seen on the sections.Therefore,the processing tests have been carried out on a seismic line that crosses the gas field.The results showed that using 20 Hz in frequency to carry out target-oriented processing can best reflect the seismic response to the gas-bearing bed,such as dim spot,plat spot,event downwarping,low-frequency effect and polarity reversal etc. The planar distribution of gas reservoir in separate layers can be predicted according to these characters,that meets the need for development of gas field.
