In this static correction, the events are manually picked on CRP stack section (X-component), and the corresponding P-component data are used as a judgement .

Velocity-scanning analyzed technique in CRP gather of 3-D prestack depth migration and its application.;

Based on the method of well-seismic comparison of composite seismic traces,through the composite seismic traces,the stacked profile CRP gather,angular gather were comparatively analyzed,by which the differences existed in different seismic data of the composite seismic traces were indicated.

Therefore this paper will discuss a method of near offset stack and compare its results with those of full offset stack,indicating that near offset stack can preserve high frequency and suppress random noise.
