Abstract:

Based on high resolution interpretation of sequence stratigraphy,3-D velocity field processed with AVO is used to perform AVO attribute inversion,spectrum analysis,attribute attraction and wave form analysis to get reservoir information.Through combining the reservoir information with interpretation results of seismic and sedimentary facies of the reservoir,integrated seismic processing and interpretation in profile-plane-space is carried out to assign correct geologic meaning to seismic attribute information,so as to realize accurate prediction of reservoir distribution.This method has been used to study the first member of Badaowan Formation in Moxizhuang area,central of Junggar basin.The results show that the plane reservoir distribution achieved through AVO attribute inversion and wave form analysis has good coincidence with that achieved by using theory of high resolution sequence stratigraphy.

Key words: seismic processing, interpretation, integration, high resolution sequence statigraphy, accurate reservoir prediction
