一种各向异性参数联动时深转换方法
摘要：
本发明提供了一种各向异性参数联动时深转换方法，属于油气地球物理勘探地震资料处理领域。本方法包括：(1)地震数据准备：CMP道集和各向同性介质深度域的层速度VPO；(2)给定偏移距深度比为1，对CMP道集中偏移距深度比的值小于1的数据进行各向同性动校正速度扫描得到时间域的等效Vnmo；(3)对CMP道集中偏移距深度比的值大于1的数据进行水平速度或者非椭圆率值扫描得到时间域中的等效水平速度Vh或时间域的等效非椭圆率η；(4)对步骤(2)和步骤(3)得到的数据进行DIX转换得到时间域的层间Vnmo、时间域的层间Vh或者时间域的层内的非椭圆率η；(5)建立时深关系；(6)进行时深转换。
摘要（英）：

The invention provides an anisotropy parameter linkage time depth conversion method and belongs to the oil gas geophysical exploration earthquake data processing field. The method comprises steps that (1), earthquake data such as a CMP trace gather and isotropy medium depth domain layer speeds VPO is prepared; (2), the given offset distance depth ratio is 1, isotropy normal dynamic correction speed scanning on the data having the offset distance depth ratio smaller than 1 in the CMP trace gather is carried out to acquire equivalent Vnmo of a time domain; (3), horizontal speed or non-ellipticity value scanning on the data having the offset distance depth ratio greater than 1 in the CMP trace gather is carried out to acquire equivalent horizontal speed Vh of the time domain or equivalent non-ellipticity eta of the time domain; (4), DIX conversion on the data acquired in the step (2) and the step (3) is carried out to acquire interlayer Vnmo of the time domain, interlayer Vh of the time domain or in-layer non-ellipticity eta of the time domain; and (5), time depth relation is established; and (6), time depth conversion is carried out.
