Seismic technology application in progressive development of lithologic reservoir—an example of 3D area of DT in Subei Basin

摘要

Seismic technology is used in this article to discuss the type and scale of reservoirs of E_2d_1 formation in DT 3D development area of JH Sag in SB Basin. Full 3D interpretation is conducted by taking full advantage of seismic technologies. Fault plane composition and elaborate interpretation of structure are studied by using time slice. Forward modeling technology (AIMS) is used to research genetic mechanism of seismic wave of objective intervals and to analyze the relationship between the onlap point of T_2~5 reflection and that of real objective interval. ISIS global optimum multi-channeled inversion system is utilized to predict the sand body in objective intervals, and define the possible distribution arrange of the sand body and possible oil-bearing domain. Finally, very good development effect is achieved.
