Abstract:

Some gas layers with abnormal seismic response characteristics were found in recent years in the Yinggehai Basin. By means of studying the P-wave velocity changing of gas reservoir and seal, the reasons of the new type of seismic response characteristics formed in gas reservoir were analyzed. Compared with the normal seismic response characteristic of “two red with one black” of gas reservoir, the new type of seismic response characteristics of “upper black down red” and “upper red down black” made the seismic response type of gas reservoir richer, which broadens the thought for finding the potential target. In addition, the study of logging rock physics shows that the P-wave and S-wave velocity changing of seal may have the relationship with the AVO type of gas reservoir, and different P-wave and S-wave velocity curve shape corresponds to different AVO type. So we can roughly distinguish the AVO type according to the P-wave velocity, S-wave velocity and P-wave impedance curve shape in the prestack AVO study.
