Abstract: By practices of lithologic targets prospecting in eastern Junggar basin, this paper highlights the key role of forward modeling technology in seismic data interpretation and processing from the following 4 aspects: (1)the quality monitoring in seismic data processing;(2)the corresponding geological meanings to the seismic reflection events; (3)the feasibility of identification for the reservoir covered by Xis?hanyao coal bed of the Jurassic; and (4)the restriction of diachroneity of the isochronic sequence interface. The results show that the effect of this method is remarkable in application in this area
