This article focuses on the seismic data model. It is the entity that the data content of the system of the seismic database is established according to a certain format. Seismic data and working parameters observed so far are divided into ten kinds of data, and these ten kinds of data are divided into sixteen kinds of data files. Sixteen kinds of data logic records and data items are designed. Proposed master data files and data files from the main index directory.
