Algorithm of Tracking Reflection Events of Seismic Based on Wave Form Similarity

在地震勘探中,反射波同相轴追踪拾取是地震资料解释的一项重要的基础工作,追踪拾取的正确与否将直接影响最终解释成果的准确性。在研究了各种同相轴自动拾取思想的基础上,依据反射波波形高度相似的特点提出了一种基于波形相似特征的反射波同相轴追踪算法"。经使用matlab软件进行模拟试算和实际资料试算,证明该算法简单有效,计算速度较快。

In seismic exploration,the tracking reflection events is fundamental in explaining seismic data,which affect the final explanation result. After researching the automatic picking of various phase axes,according to the similar height of reflecting wave form,this paper puts forward a tracking algorithm of the reflection event based on wave form similarity. Matlab is applied to simulate a trial calculation and real data calculation,and proved to be simple,effective,and fast.
