摘要
从江汉盆地平原海相资料特征出发,认为应针对具体情况选择有效的处理方法。在江汉首次提出了广角反射信息提取、CMP超道集交互动态动校切除等处理方法,确定了合理处理流程。通过大量实际资料处理,表明这些方法在平原海相资料处理中发挥了独特作用。
In combination of the characteristics of plain-marine data in Jianghan Basin, it is considered that an effective processing method is selected according to concrete situations. Methods of wide-angle reflection information extraction, CMP superchannel collecting-interaction and dynamic calibrating cutting are proposed for the first time in Jianghan Basin. Rational processing flowsheet is established. Large number of data processes show that these methods play special roles in the plain-marine data processing.
