在地球物理勘探中，地震资料计算机显示方法主要有：变密度彩色显示、波形显示、变面积黑白（填充波形）显示等，其中变面积显示方式在数据采集和资料处理阶段使用最为广泛。现有变面积显示技术在查看小范围数据时波形填充显示效果比较好，当扩大显示范围时由于屏幕分辨率限制，只能对波形进行抽希显示，这种现实方法精度不高，显示效果不美观。本文提出一种基于灰度的变面积绘制方法，将像素位置看成一个单元，首先统计要填充的波形落在单元内部的强弱权值，最后根据每个单元内的波形权值设置像素的颜色深浅，即使用颜色的深浅表示波形的强弱。实验表明，本文提出方法绘制的地震剖面显示精度更高，效果更加美观。

Currently in geophysical exploration, there are some kinds of methods for seismic waveform display with computer: variable density color display, waveform display, variable area filled waveform display, etc. The variable area filled waveform display effect is good when displaying small range data. However, when the display range expands, due to the limit of screen resolution, the only way is to resample data. This method's accuracy is not high, showing unsightly. This article describes one method for display waveform which is based on gray variable area. Take every pixel as a unit, add up the power of wave in the unit, then use the power to calculate the blackness, which means using the blackness to show the waveform. Experiment shows that the seismic profile displayed with this method has higher accuracy, and the effect is more beautiful.
