Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0027] The present invention migrates the idle seismic data from the high-end storage unit (i.e. the first storage unit) to the low-end storage unit (i.e. the second storage unit) according to the visit times of the seismic data, the visit times of the work area information database and the usage coefficient of the seismic data. ), releasing storage space with higher cost.

[0028] figure 1 is a block diagram showing a seismic data hierarchical storage device according to an embodiment of the present invention.

[0029] The hierarchical storage device for seismic data of the present invention includes a first counter 100 , a second counter 200 , a controller 300 , a first storage unit 400 , a third storage unit 500 and a second storage unit 600 .

[0030] The first storage unit 400 stores seismic data of a work area as a survey object. Here, the first stora...

Abstract

The invention provides a device and a method of seismic data hierarchical storage. The device of the seismic data hierarchical storage comprises a first storage unit, a second storage unit, a third storage unit, a first counter, a second counter and a controller, wherein the first storage unit is used for storing seismic data of a work area as a geological prospecting object, the second unit is used for storing the seismic data which are moved out from the first storage unit, the third storage unit is used for storing a work area information data base used for searching the seismic data stored by the first storage unit, the first counter is used for recording the first visit times of the seismic data stored in the first storage unit in preset time, the second counter is used for recording the second visit times of the work area information data base in the preset time, and the controller is used for moving the seismic data in the first storage unit to the second storage unit based on the first visit times and the second visit times.

Description

technical field [0001] The invention relates to seismic data storage technology in the field of geophysical exploration, in particular to a seismic data hierarchical storage device and method. Background technique [0002] In contemporary petroleum seismic exploration, 3D seismic exploration has become the mainstream technology, and the current seismic exploration data scale and access have the following characteristics. [0003] 1. Large amount of data: Seismic data of petroleum physical exploration can be divided into original single-shot seismic data, intermediate seismic data, final Results seismic data and auxiliary seismic data (such as coordinates, location of observation points, etc.). After the popularization of 3D seismic exploration projects, seismic data has grown geometrically, and the data volume of a single seismic data analysis center has reached the PB level (1PB=1024TB). Among them, the original single-shot seismic data and intermediate seismic data have ...
