【Abstract】 To meet the need of exploration and exploitation under complex geological condition, some basical theoretic propositions of improving the level of the seismic wave’s propagation and imaging are illustrated in this article. Some key problems in numerical computation are presented also. It is only in according with the difficulties that may be faced in extracting the geological attributes and building the model of reservoir with seismic data. Those results are emphasized on some actual images to describe the necessity of this kind of research. As we known, old oilfields in the east of China are main supports of our national economics. The exploration and exploitation of "Pre cenozoic Marine Carbonate Rock" and these oilfields’ periphery and deep part are two objects of research. In respect of the progress in seismic migration, imaging and reservoir model building, these two are all difficult to promote the theory of exploration in recent years although some differences exist in the age and process of geological evolution. Author also explains why this kind of research is serious.更多还原
