Seismic full horizon tracking method, computer device and computer-readable storage medium

A computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein when executing the computer program, the processor implements the following methods of:

• acquiring three-dimensional seismic data;
• extracting horizon extreme points from the three-dimensional seismic data to construct a sample space;
• equally dividing the sample space into a plurality of sub-spaces with overlapping portions, and performing a clustering process on the horizon extreme points in each sub-space to obtain horizon fragments corresponding to each horizon of the three-dimensional seismic data;
• establishing a topological consistency between the horizon fragments;
• and
• fusing the horizon fragments corresponding to each horizon of the three-dimensional seismic data based on the topological consistency, to obtain a full horizon tracking result of the three-dimensional seismic data.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores a computer program executing the following methods:

• acquiring three-dimensional seismic data;
