Abstract：The precision of velocity analysis and imaging of complex structures are the issues that are difficult to be solved in seismic data processing,but both of them rely on each other,i.e.imaging of complex structure is built on the fine velocity analysis basis.In view of the developing situation of seismic data processing techniques,the optimum methods the abovementioned two issues are solved are to perform fine prestack velocity inversion and prestack time (or depth)migration~ [1,2].It is proved by prestack time migration processing of seismic data in Guanjiapu area of Dagang oilfield that prestack time migration solved the imaging problem in Guanjapu area characterized by complex structural and lithologic variation,reducing the cost and providing reliable guarantee for evaluation of development,improving drilling successful rate and reducing scheme risk investment of Guanjiapu oilfield.
