Three-dimensional dip angle domain stationary phase pre-stack time migration method and system

The invention discloses a three-dimensional dip angle domain stationary phase pre-stack time migration method and system. The method comprises the steps that pre-stack seismic data are read, and a migration speed field and a stretching and removing parameter are determined; according to the migration speed field and the stretching and removing parameter, two dip angle channel sets corresponding to dip angles in the directions parallel to and perpendicular to a measuring line respectively are generated through a selected imaging line; based on the two dip angle channel sets on the selected imaging line, Fresnel zones in the two dip angle directions are picked up, and the Fresnel zones of all imaging points on a quasi imaging block are obtained through interpolation; through the obtained Fresnel zones of all the imaging points, three-dimensional stationary phase pre-stack time migration is carried out, and migration results corresponding to different migration distances are obtained; the migration results of three-dimensional stationary phase pre-stack time migration are collected, and a three-dimensional imaging data body is formed; the three-dimensional imaging data body is converted into a profile image of an underground reflection structure. According to the method and system, the problem that when a high dip angle structure exists, the signal to noise ratio of the migration image obtained through an existing migration imaging technology is low is effectively solved.
