基于MATLAB实现地震速度切片成图

Seismic Velocity Slice Drawing Based on MATLAB

野外采集的天然地震数据一般都庞大而复杂,我们无法从这些地震数据中来判断出隐含的地质现象和规律,所以有必要将这些经过预处理的天然地震数据运用科学可视化技术直观地显示出来。针对天然地震数据的特点,运用MATLAB强大数学计算和图像可视化功能绘制出新疆地区地下300km内八层的水平速度切片图,从而可以直观地了解地下各个区域的速度变化情况,为地质研究人员研究新疆地质特征提供参考。

Natural seismic data collected from the field is generally lager and complex, so it is hard to find connotative geological phenomena and rules. It is necessary to display seismic data with scientific visualization technology after processing. According to seismic data characters, this paper shows horizontal velocity slices 300 km underground based on MATLAB software scientific calculation and visualization. These slices can show underground velocity change trend and provide references for geologist who study Xinjiang geologic characters.
