Abstract

Provided are a device and a method for storing a seismic data cube and reading seismic channels. The device for storing the seismic data cube and reading the seismic channels comprises a storage unit used to store the collected seismic data cube together with an established tree indexing group, an attribute value acquisition unit used to acquire attribute values of N attribute fields of seismic data of each seismic channel to be read, a store address retrieval unit used to retrieve store addresses of the seismic data of each seismic channel to be read step by step in the tree indexing group based on the acquired attribute values of the N attribute fields and a seismic data reading unit used to read the seismic data from the storage unit based on the retrieved store addresses, wherein the tree indexing group is related to the store addresses of the seismic data of a plurality of the seismic channels included in the seismic data cube, and includes N levels of index nodes established according to a sequence of N keywords. According to the device and the method for storing the seismic data cube and reading the seismic channels, the needed seismic data can be rapidly read from the seismic data cube.

Description

technical field [0001] The invention relates to the technical field of geophysical exploration, and more specifically, relates to a device and method for storing seismic data volumes and reading seismic data of seismic tracks. Background technique [0002] With the continuous development of seismic exploration technology, especially the development of high-precision seismic acquisition technology, the data volume of seismic data volume is increasing. How to quickly read seismic data from the seismic data volume has also become a difficult problem in the processing and interpretation of seismic data. [0003] On the one hand, in the processing and interpretation of seismic data, it is often necessary to process and interpret seismic data that meet certain conditions, which makes it necessary to scan all the seismic data in the seismic data volume every time to determine the required seismic data , so that it takes a long time to acquire seismic data each time. [0004] On t...
