地震勘探采集的地震数据一般以地震道为单位进行组织,采用SEG-Y文件格式存储。SEG-Y格式是由SEG (Society of Exploration Geophysicists)提出的标准磁带数据格式之一,它是石油勘探行业地震数据的最为普遍的格式。读取数据后经过处理可以得到有关地下构造和岩性等大量有用信息信息。但是原始数据数据量庞大而且杂乱无章,为了使大量的数据变得直观、易于理解,揭示数据间的内在联系,必须对原始数据经过一系列变换转换成图形图像,将信息以更容易理解的形式展现出来。VC++功能强大、界面友好且操作方便,因此目前PC机上通常在VC++环境下对这种格式存放地震勘探数据进行处理并实现可视化显示。笔者在做地震数据可视化时利用VC++6.0编写了地震数据的读取处理程序及绘图程序。-Seismic exploration seismic data acquired seismic traces generally organized as a unit, using stored SEG-Y file format. SEG-Y format is one of the standard tape data format by the SEG (Society of Exploration Geophysicists) proposed, it is the most common oil exploration industry seismic data format. After reading the processed data can be obtained about the subsurface structure and lithology information a lot of useful information. But the huge amount of data and disorganized the raw data in order to make large amounts of data becomes intuitive, easy to understand, reveals the intrinsic link between data must go through a series of transformations of the original data is converted into graphic images, the information in a more easily understood form of show come out. VC++ features powerful, user-friendly and easy to operate, so now usually in the VC++ environment seismic data stored on the PC for this format to be processed and visualized display. I do seismic data visualization use VC
