Problems solved by technology

The rapid development of exploration technology requires that the header data of seismic data must also develop accordingly. Seismic data with fixed header structures can only define more header characters through software upgrades and standard upgrades, but software upgrades will bring There are many problems such as incompatibility of the software itself, the system and supporting software

Abstract

The invention provides a seismic data conversion method and device based on a dynamic trace header. The seismic data conversion method based on the dynamic trace header comprises the following steps:obtaining header data, trace header data and seismic record trace data of seismic data to be converted; respectively setting the volume head data, the trace head data and the earthquake main data at corresponding positions in respective preset databases to generate converted volume head data, trace head data and earthquake main data; generating target seismic data according to the converted headerdata, trace header data and seismic main data. The seismic data conversion method and device based on the dynamic trace header have the advantages that the seismic data structure is optimized, and the expandability of seismic data trace header information is improved.

Description

technical field [0001] The invention relates to the field of petroleum exploration, especially the processing of seismic data in the field of petroleum exploration, and in particular to a seismic data conversion method and device based on a dynamic track head. Background technique [0002] Complete seismic data consists of volume header, seismic trace and track header. The part that describes the common attribute information of seismic data is called header, such as sampling interval, seismic record track type, etc.; There is a one-to-one correspondence with the seismic records, and it is a collection of header characters, and each header character describes an attribute information of the header. A seismic trace is a collection of sample data values ​​sorted by time (or depth). [0003] At present, the common organization method of seismic data trace headers is fixed trace headers. Fixed track headers can be described as: the seismic traces (track header data) of differe...
