Data Processing By Pre-stack Link-area In Tazhong162-6

The I fault-zone is one of the signified areas in Tarim Base exploration, and has a enormous potential. There is not a linked seismic field acquisition data in TaZhong 162-6 area, so it is indispensable to process seismic data by Pre-stack link-area.Though every one technology which used in data processing is advanced by the history of the processing project by pre-stack link-area in Tarim Base, two problems are presence. First, The Surface-Consistent-Process merely deals with the surface-seismic data, and do not consult the well information. Second, It is not consummate to optimize cmp gather for migration, and essential to apply some reasonable optimized method. In a word, those two problems may be resolved by technology compounding along with the evolution of the geophysics, and the final imaging may be more veracious.This dissertation described the principle of linking project and surface consistent processing based on Q and optimizing gather before pre-migration, generated the technique combination, performed the processing flow which consist of linking project and surface-consistent compensation based on Q and surface-consistent deconvolution based on Q and optimizing the cmp gather before pre-migration by seismic data processing in Tazhong 162-6 area. The final result demonstrated the authentic amplitude, elevate the resolution and signal-to-noise, promoted the exploration of the TaTzhong area, obtained perfect effect. The innovation could extend the entire Tarim base, which launched in 3D pre-stack link-area processing.
