The parameters of bin-divisible 3D seismic geometry are different from that of conventional 3D geometry, which can obtain data with different bin size. The faulted system of Siwujiazi-Bawu area of Shiwu Fault Depression in the south of Songliao Basin is developed with many small faults. In order to improve the imaging accuracy of fractured small faults, bin-divisible geometry is utilized to acquire seismic data. In seismic data processing, some key techniques were used, including tomography statics, multi-domain denoising, surface consistent deconvolution, CMP rearrangement, stratum recalculation and pre-stack time migration. By analyzing, processing and interpreting the high-precision bin-divisible 3D seismic data in Siwujiazi-Bawu area, different kinds of geologic problems were solved, and the results were achieved.
