Application of geophysical exploration technology in strike-slip fault zone,western Bohai Sea

The research on strike-slip fault zone has always been the hotspot for tectonic analysis of Bohai Sea,however,theresearch on Neogene strike-slip fracture characterization is relatively few.Through various geophysical technology parameters testing and comparison research,the description on the strike-slip fault zone characterization has been carried out and it received good application effects.By using submarine cable wide azimuth acquisition technology,attribute analysis and filter coherent technology,the fracture analysis accuracy and tiny fracture identification ability have been improved.With the post-stack target processing technology,the seismic event continuity has been enhanced and the imaging precision of fault and buried hill top surface has been improved.Through application of various geophysical exploration methods,the complex strike-slip fault zone tectonic evolution characteristics have been identified and the Neogene dextral strike-slip displacement analysis has been completed for the first time.
