摘要：Es2 member reservoir of Guojuzi sag is located in the east Bohai Bay Basin in China, mainly composed of beach bar sediments, which are thin and in irregular distribution. Conventional post-stack seismic attributes cannot predict the reservoir effectively, while pre-stack seismic inversion also has difficulties in application for the low SNR seismic data. A number of amplitude preserved processes are taken to obtain high SNR seismic data. Then AVA simultaneous inversion is adopted to achieve elastic parameters. Well log analysis shows that µρ and lower Vp/Vs can be good indicators for our target reservoir, therefore we extract µρ and Vp/Vs attribute sections and slices from the result of AVA simultaneous inversion and have successfully delineate the spatial distribution of Es2 member reservoir, which are in consistent with the known well log data.
