高分辨率水平叠加方法及应用

Application of high resolution horizontal stacking method

叠加技术可提高地震资料的信噪比和分辨率,但当地震波非同相叠加时,就会使高频信号受损,影响地震资料的叠加效果.针对叠加技术进行了具体分析,结合实例,提出了一种分步处理方法,即先进行剩余时差校正,然后做频率域叠加.通过对理论资料和实际地震数据的处理,验证该方法的可行性.

In order to improve the resolution and signal-noise ratio, horizontal stacking technique usually used to be employed before. But high frequency signal could be damaged when seismic waves were unable to achieve the goal in phase stacking. So people advanced some methods in real seismic data processing, which, however, was not very perfect. Based on those problems we analyzed particularly examples to give a new processing method, which can correct the residual move out correction of each trace and perform the stacking in frequency domain, theoretical real result shows that the method is promising.
