Problems solved by technology

[0003] The current technical solution is to choose to store all the travel time tables in the disk. In the subsequent integral imaging process, due to the frequent access to the travel time table, it is necessary to frequently access the disk, so that the travel time tables stored in the disk are stored in batches in the memory. , so that most of them are busy with frequent access to the disk during the integral imaging process, and the calculation efficiency is greatly reduced

Abstract

The embodiment of the invention relates to a travel time table distributed storage method and device. The method comprises: determining the number of servers; from all the servers, determining one server as a main server according to a preset rule; for a travel time table corresponding to any seismic work area grid or travel time tables corresponding to multiple seismic work area grids at each moment, storing the travel time tables in a server cache in real time by using a preset algorithm; establishing a travel time table storage index in real time according to a travel time table corresponding to any seismic work area grid or identifiers of travel time tables corresponding to a plurality of seismic work area grids at each moment and identifiers of servers for storing the travel time tables; and storing the travel time table storage index to the main server, wherein the travel time table corresponding to any seismic work area grid at each moment or identifiers of travel time tables corresponding to a plurality of seismic work area grids in the travel time table storage index are in one-to-one correspondence with identifiers of servers storing the travel time tables.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of geophysical imaging, and in particular to a distributed storage method and device for travel time tables. Background technique [0002] Kirchhoff depth migration is a key method of geophysical imaging, which consists of two steps: travel time calculation and integral imaging. The travel time information generated by the travel time calculation is stored, which is called the travel time table. Due to the large data volume of the travel time table, in the traditional calculation method, the data volume of the travel time table can be reduced by 10,000 or tens of thousands of times after extracting the travel time table and converting the code, but the data volume of the travel time table in large seismic work areas is still It is very large, for example, the amount of data in the travel time table is still more than 1T. [0003] The current technical solution is to choose to store al...
