江汉平原海相低信噪比地震资料处理方法研究

How to Handle Low Signal-to-Noise Ratio Data of Marine Facies in Jianghan Plain.

针对江汉平原海相地震资料静校正问题突出、干扰波发育、信噪比低等特点,研究采用层析静较正,叠前多域去噪,CRS叠加等关键技术提高平原海相资料成像品质,并总结出一套适合江汉平原海相低信噪比地震资料处理方法。

In order to overcome the deficiencies of the plane and marine seismic data which are the obvious problem with static correction, development of interference wave and low signal--to--noise ratio, this paper sought to improve the quality of plane and marine facies imaging and raise signal--to--noise ratio with tomographie static correction, pre--stack noise elimination, CRS and other key techniques while come up with a set of material processing method to handle the low signal--to--noise ratio data of marine facies in Jianghan Plain.
