通常纵波入射且当入射角大于临界角时,由于反射系数的变化,角道集记录发生相位畸变,为实现同相叠加,要在叠加之前进行相位校正。
3.
Regarding the low signal-to-noise ratio(S/N Ratio) which widely exists in AVO attribute analysis,a resolution workflow was proposed as the following:the angle gathers were partially stacked,then the partial stacks of the angle gather were input and used in the AVO processing and analysis.
本文针对AVO属性分析中普遍存在的角道集资料信噪比低的问题,使用了将角道集部分叠加后再将多个部分角叠加数据体作为AVO处理输入数据的解决方法,进行了AVO属性处理,并对垦东北部馆上段Ⅳ、Ⅴ砂组进行了AVO属性分析,结果表明横波阻抗及μρ数据对岩性识别效果突出,泊松比及大角度叠加地震数据对油气响应敏感,其中利用大角度叠加地震数据沿层提取的油气检测平面图与实钻结果吻合率高达93%。

【诗文】:
诗源何代失澄清,处处狂波污后生。常感道孤吟有泪,
却缘风坏语无情。难甘恶少欺韩信,枉被诸侯杀祢衡。
纵到缑山也无益,四方联络尽蛙声。
