oa The Analysis of AVO Dispersion Attributes in Thin Tight Inter-layer Reservoirs

Analysis of AVO dispersion has been one of the hottest topics of reservoir prediction, it can improve the precision of hydrocarbon detection. The previous researches show that strong velocity dispersion and dissipation will appear in petroleum and hydrocarbon reservoir, it also can be a new fluid indicating parameter used to detect hydrocarbon. Horizon interpretation is complicated and difficult in thin inter-layer reservoirs. Therefore, thin inter-layer models are constructed to confirm the usefulness of AVO dispersion value in such layers, and frequency division processing is used to help reservoir prediction. Then make dispersion analysis for a gas field to further confirm its availability in real data.
