Abstract: DZ region has favorable reservoir conditions,it has important significance to carry on integration of high-precision seismic data acquisition,processing and interpretation tosearch for the complex,hidden hydrocarbon reservoir and reservoir lithology prediction in the area . Aiming at variable surface geological conditions and complex structure types,carrying on high precision fine seismic data processing basedon fine high precision acquisition to improve the resolving power of seismic data in space and time,signal to noise rati-o,the accuracy of the velocity field,thereby improving the superposition quality of small amplitude structures and migration imaging accuracy.
