In this paper, using the results obtained from the special data processing for the data collected from the transitional belt of Middle-South sichuan province ci cincluding the envelope of the instantaneous amplitude, the instantaneous phase, the bright spots, and the acoustic impedance, etc.) to the searching for oil/gas reservoir was described. Also described in this paper is the identification keys of the seismic anomaly indicating the presence of oil/gas. The validity and the feas sibility of the fechniques used were illustrated by examples. It is believed that th the reservoir in this area is featured with wide distribution as well as multiple layers. Obviously, it is an area where the non-anticlinal oil/gas reservoir is in h high potential.
