AI Technical Summary
Technical Problem
Existing technologies have significant errors when extending anisotropic parameters to a larger area, resulting in unclear OVT imaging.
Method used
The curve wave coefficients of seismic data are extracted by curve wave transform algorithm. The anisotropic parameters of each curve wave coefficient are used to repair the OVT gather. The anisotropic parameters are calculated by combining tilt information and key parameters of the trace head, and targeted repair is carried out.
Benefits of technology
It improves the repair accuracy and imaging effect of OVT gathers, ensures the correction of seismic wave propagation paths, reduces the risk of structural misjudgment and reservoir characteristic misestimation, and improves the success rate of exploration and development.

Abstract
This disclosure relates to the field of computer technology, and particularly to a gather repair method, apparatus, device, storage medium, and computer program. The gather repair method includes: acquiring seismic data, the seismic data including multiple seismic coordinate points, the seismic coordinate points being the coordinate points where earthquakes occur, and the seismic coordinate points being located in a Cartesian coordinate system; extracting curvelet coefficients corresponding to at least one spatial parameter of the seismic data based on a curvelet transform algorithm to obtain at least one curvelet coefficient; acquiring source-receiver offset vector surface element (OVT) gathers corresponding to the at least one curvelet coefficient, the OVT gathers being seismic data with the same spatial information; extracting anisotropy parameters of each curvelet coefficient, and using the anisotropy parameters of each curvelet coefficient to repair the corresponding OVT gathers, obtaining target OVT gathers corresponding to each OVT gather. The embodiments of this disclosure improve the accuracy of gather repair.
