摘要
利用角度扫描法对各向异性介质中快慢波的方位角和时间延迟进行分析是预测裂缝的一种比较有效的方法.转换横波在经过裂缝等波阻抗界面较明显的反射界面时,由于横波分裂使原始地震资料各分量的能量重新分配到快慢横波中,通过角度扫描法可以将发生横波分裂现象而分散于垂直裂缝和平行于裂缝两个方向上的快慢横波能量重新集中,恢复成没有发生横波分裂现象前的转换横波波场信号.为此,通过建立一套裂缝预测的流程并将其应用到胜利实际资料的处理中,对时间延迟进行校正并对裂缝方向进行预测,使转换波R分量的成像质量有了较大的提高.
Using angle scanning method is an effective way to predict fracture by analyzing azimuth angle and time delay in fast and slow wave.When converted shear wave penetrate across reflector with obvious wave impedance interface,raw component energy will be splitted into fast and slow shear wave,according to angle scanning method the shear wave energy which is parallel and perpendicular to the fracture can be concentrated again,then we can get the shear wave before it have shear wave splitting phenomenon.For this reason,through the establishment of a set of fracture prediction process and applied it into the actual data processing,we correct the time delay and predict the fracture' s angle which makes the converted R-component imaging quality greatly improved.
