Abstract：The quality of available regional seismic data in the Tuha Basin, mainly spliced by the data of three-dimensional (3D) blocks, varies greatly, which can hardly meet the needs of overall regional research. Therefore, we use the GeoEast system to carry out the merging processing of three-dimensinal (3D) seismic data of 20 blocks in Shengbei Sag of the Tuha exploration area. We employ the static correction technique for tomographic inversion constrained by uphole surveys, wavelet consistency processing technology, true pre-stack combined denoising technology, bin averaging technique, etc. These techniques can well eliminate the differences between seismic data from different blocks, improve the quality of seismic data, and provide technical support for overall regional evaluation research. The research also shows that the GeoEast system has a powerful function of merging processing for basin-level seismic data.
