Embodiment 1

[0025] The invention discloses a method for describing seismic data data, which separates seismic trace headers and seismic line headers from seismic data bodies, and divides data files into three parts: seismic data line headers and trace headers, seismic data bodies, and data In the index file, the headers of the seismic traces are first defined and then used correspondingly. The meanings and corresponding positions of the headers of each seismic trace are arbitrarily specified by the user.

Embodiment 2

[0027] The best implementation mode of the present invention is: the seismic track head and the seismic line head are separated from the seismic data body, and the data file is divided into three parts: the seismic data line head and the track head, the seismic data body, and the data index file. The headers of the seismic headers are first defined and then used accordingly. The meanings and corresponding positions of each seismic header are arbitrarily specified by the user. The trace head of the seismic trace is first defined and then correspondingly used. The meaning and corresponding position of each seismic trace header word are arbitrarily specified by the user and specifically include:

[0028] 1. Storage method of seismic data trace head

[0029] Seismic data trace header files are composed of public information description, line header attribute information, trace header attribute information, line header data, and several trace header data. The meanings of each part ...

Abstract

The invention discloses a method for describing seismic data, relating to the technical field of processing and explaining seism exploring data in petroleum seismic exploration. The method comprises the following steps: separating a seismic channel head and a seismic line head from an seismic data body; dividing a data file into three parts, namely a seismic data line head and channel head, a seismic data body and a data index file; and defining seismic channel head firstly and then using the seismic channel head, wherein the meaning and corresponding position of a seismic channel head character are appointed randomly by a user. The method has high data accessing efficiency and fully satisfies the requirements for accessing the seismic data randomly; after the data file is divided into three parts, the data file basically has no redundancy information, so that system resources are saved and the work efficiency for processing and explaining is improved.

Description

[0001] technical field [0002] The invention relates to the technical field of processing and interpretation of seismic exploration data in petroleum seismic exploration. Background technique [0003] Seismic data is a very important data resource in the research work of oil and gas exploration and development. It is a typical unstructured data with complex format and huge data volume. [0004] The method for describing seismic data data that is usually used in seismic data processing and interpretation work, as the publication number is 1046983, and the publication date is that the Chinese patent document on November 14, 1990 discloses a method for describing oil reservoirs with seismic data. It is characterized in that the technical method includes the following steps: a. Obtaining formation background velocity, formation background density and formation background acoustic impedance; b. Obtaining formation residual velocity, formation residual density and formation r...
