Abstract: Due to the seismic multiple wave and conversion wave are well developed in Bachu-Dongnong area, it has obviously influenced the quality of processed data. The paper proposed the routine used method for multiple wave identification, the τ-P domain automatic identification method, and combination method of normal modeling calculation with explanation to identify the multiple wave. Also, a set of multiple wave suppression processing procedures suited to that particular area is presented. Practical application showed the results are good enough.

Key words: Tarim basin, Bachu arch, multiple reflection, conversion wave, τ-P domain wave field, model, normal conversion
