Primary reflections are generally applied in seismic imaging. The information of primary waves, however, is insufficient for structural imaging in obstacle restricted areas where no shots but only receivers are allowed. Multiples, if developed, can be applied as effective signals. In this paper, the author presented to take multiples as effective information to highlight the obstacle area and supplement the incomplete image obtained by only primaries reflection in obstacle restricted areas, and obtain complete and rich subsurface structure information. Synthetic model and the real data application demonstrate the feasibility and effectiveness of this approach.
