两种数据存储格式之间的互相转换
|
摘要
石油地震采集的数据一般均采用SEGY(Society of Exploration Geophysicists Y)格式中的IBM32(International Business Machines)格式存储,商业化石油地震数据处理软件可以直接读取。而在PC机上开发特殊处理模块时,通常要读的数据文件要求是按IEEE(Institute for Electrical and Electronic Engineers)格式存储方式的数据。如果不进行数据格式转换,读取的数据会面目全非。为了适应两种地震数据处理软件之间的数据通讯,必须弄清楚两种数据存储方式的特征,并编制相应的互相转换程序。本文提供了两种数据存储方式之间互相转换的源程序。
Petroleum seismic data acquisition is always stored in the form of IBM32(International Business Machines)of SEGY(Society of Exploration Geophysicists Y).Commercial petroleum seismic data processing software can be directly read.And the development of the special processing module on the PC is usually required to read data files based on the IEEE(Institute for Electrical and Electronic Engineers) data storage format.If not for data format conversion,the data will be read beyond recognition.In order to adapt to both seismic data processing software between data communications,the two must clarify the characteristics of data storage,and preparation of the corresponding mutual conversion process.This paper provides the source program of the mutual conversion between the two data storage modes.
