  • In the Quaternary formation and Upper-Tertiary formation of Yinggehai Basin, except for abnormal pressure and compaction, there are mainly four factors affecting acoustic time, which are lithology variation, cementation, gas in the formation and crack.

Abstract: In the Quaternary formation and Upper-Tertiary formation of Yinggehai Basin, except for abnormal pressure and compaction, there are mainly four factors affecting acoustic time, which are lithology variation, cementation, gas in the formation and crack. They usually co-exist and are difficult to distinguish. According to the ideology of seismic processing, i.e., pre-stack noise attenuation/signal enhancement, we superpose multi-wells' acoustic time data of the same local region. In result, the information of reflecting pore characters enhances. It is an effective method to avoid other factors to disturb acoustic velocity. Furthermore, applying this method in processing velocity spectra, the predicted result of the formation pressure conforms to the measured pressure during drilling.
