Method for quickly loading and using mass seismic data

The invention provides a method for quickly loading and using seismic mass data. The method for quickly loading and using the seismic mass data comprises the following steps: step 1, acquiring cluster environment parameters and data file information; 2, calculating the position offset of the data blocks; 3, the MPI operation is started, and the starting offset and the ending offset of each block are distributed to each process; step 4, scanning data blocks by each process, obtaining related trace header and trace gather information, and establishing a first-level index; 5, scanning the first-level index of each block, and establishing a second-level index; step 6, establishing association of the data file and the index file; and 7, reading the data according to the index file. According to the seismic mass data rapid loading and using method, the block parallel technology is adopted, the loading and using efficiency of the mass seismic data can be greatly improved, implementation is achieved based on the MPI
