The sheer volume and complexity of seismic data makes it especially difficult to manage, store and access compared to other types of data
[0003] Usually, the methods used in seismic data processing and interpretation work to describe seismic data are often unsatisfactory when they are directly used in data processing, because access to specific seismic trace data and random seismic trace data Due to the lack of a complete index, it is necessary to sequentially scan the previous seismic trace data to determine its exact position in the file. This operation greatly reduces the efficiency of data access, and it is difficult to meet the requirements of random access to seismic data. Requirements; at the same time, it contains too much redundant information, the data loading speed is very slow, the reformatting efficiency is low, and the overhead of system resources is large, which has a great impact on the efficiency of seismic data processing and interpretation

Embodiment Construction
[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0017] The amount of seismic data is huge, so when accessing specific seismic trace data, especially when the seismic trace is at the last position, it is necessary to go through all the seismic data, so the waiting time is long. In order to facilitate storage and indexing, the present invention first divides a seismic data into line head information, line head data, track head information, track head data and seismic track information. Among them, the line head information is used to define the line head name, line head data type, and line head data length; the line head data is used to record important public information in seismic exploration data, such as the line number of seismic exploration, the number of sampling points of seismic data, sampling interval, seismic Data file type (workstation / microcomputer), data dimension (two-dimensional / three-dimensio...

The invention relates to the field of processing and explaining of seismic prospecting data in oil seismic prospecting, in particular to a method for storing seismic data. The method comprises the following steps of: A) selecting a seismic channel datum from a plurality of seismic channel data; B) computing a storage address in a second storage area where the selected seismic channel datum is stored; C) storing an index datum into a first storage area, wherein the index datum comprises the storage address and a channel head datum which corresponds to the selected seismic channel datum; D) storing the selected seismic channel datum into the computed storage address in the second storage area; and E) repeatedly executing the steps A) to D) until all seismic channel data are stored in the second storage area, wherein the channel head datum which corresponds to the seismic channel datum comprises shot point information and detector information.
Description
technical field [0001] The invention relates to the field of seismic exploration data processing and interpretation of petroleum seismic exploration, in detail, relates to a method for storing seismic data data. Background technique [0002] Seismic data is a very important data resource in the research work of oil and gas exploration and development, and is a valuable asset of the oil and gas industry. The sheer volume and complexity of seismic data makes it especially difficult to manage, store, and access compared to other types of data. [0003] Usually, the methods used in seismic data processing and interpretation work to describe seismic data are often unsatisfactory when they are directly used in data processing, because access to specific seismic trace data and random seismic trace data Due to the lack of a complete index, it is necessary to sequentially scan the previous seismic trace data to determine its exact position in the file. This operation greatly reduces...
