AI Technical Summary

Technical Problem

In existing technologies, there is a time difference when seismic data from different work areas are directly spliced, which makes it impossible to achieve seamless splicing, creates fault illusions, and affects the understanding of stratigraphic unity and fault depression structure.

Method used

By determining the seismic attribute information of the same target layer in the stacked data volumes of adjacent blocks, the overall time difference and time-varying time difference are calculated, and time shifting and stitching are performed to eliminate time differences caused by differences in acquisition year, method, processing method, etc.

Benefits of technology

It enables rapid and accurate elimination of time differences, ensures seamless splicing between stacked data, improves splicing efficiency and accuracy, and eliminates the illusion of discontinuity at the splicing point.

Abstract

The application discloses a seismic data splicing method, electronic equipment, a storage medium and a product, and relates to the technical field of seismic exploration. The method comprises the following steps: determining adjacent block post-stack data bodies, and acquiring seismic attribute information of the same target layer of the adjacent block post-stack data bodies; determining the overall time difference of the adjacent block post-stack data bodies according to the seismic attribute information of the same target layer, and determining target adjacent block post-stack data bodies based on the overall time difference and the adjacent block post-stack data bodies; acquiring common midpoint points of seismic profiles in the target adjacent block post-stack data bodies, determining time-varying time differences corresponding to each common midpoint point according to the seismic attribute information corresponding to the common midpoint points; performing time shifting on the target adjacent block post-stack data bodies according to the time-varying time differences, and splicing the target adjacent block post-stack data bodies after time shifting based on the common midpoint points of the target adjacent block post-stack data bodies. According to the embodiment of the application, the time difference of the post-stack data bodies is quickly eliminated, and seamless splicing between the post-stack data bodies is truly achieved.
