Abstract: Along with the advance of exploration degree in Dongpu sag,the lithlogic and the structural-lithologic subtle reser- voirs have become the targets for rolling exploration to in- crease reserves and potential resources.On the base of the modern sedimentology and sequence stratigraphy,a integra- tive evaluation on reservoir and the oil and gas pool forma- tion are performed,and drilling targets are predicted.Ac- cordingly,a set of integrative seismic interpretation tech- nique and flow suitable to the exploration and development of subtle reservoir is established,namely as seismic inversion as core,with 3D visualization,seismic facies analysis and seis- mic attribute analysis as matching interpretation techniques.
