基于VC++的SEGY数据格式地震剖面图绘制
|
摘要
地震数据显示是地震资料解释的基础,将数据转换为图形的形式在屏幕上显示出来可以使其更加直观、易于理解。本文在分析了SEGY格式地震数据文件结构的基础上,利用VC++实现了地震数据的准确读取,完成了波形、面积填充和变密度这几种常见地震数据剖面显示方式的绘制。对绘制的原理和过程进行了介绍,并展示了绘制结果。
The seismic data presentation is the foundation of seismic data interpretation,converting the seismic data into graphics or images and showing them on the screen can make it more intuitively and understandable.Using Visual C++ 6.0 as development platform,seismic data excat reading is realized,several common seismic profile displaying patterns are completed such as the waveform graph,area filling and variable density displaying based on the analysis of the the structure of SEGY file,The principles and process of drawing are introduced.At last the results of drawing are also demonstrated in the thesis.
