松辽盆地南部深层地震资料处理方法研究

Process method study of deep raw seismic records in southern Songliao Basin

针对松辽盆地南部深层原始地震记录接收能量弱、信噪比低、各种干扰波严重和地表条件多变等存在严重的静校正问题,尝试利用CGG、Foucs、Grisys 、Promax等多套处理系统的优势模块对跨工区二维大剖面进行深部地层的折射波静校正、反褶积、剩余静校正、DipMoveOut、偏移等关键技术的联合处理方法试验研究,形成了一套针对松辽盆地南部深层地震资料处理的有效方法。

Deep raw seismic records in southern Songliao Basin have many problems such as low ratio of signal to noise,all kinds of noise,low receiving energy and severe static correction caused by complex surface. In order to overcome these difficulties,multi-system including CGG,Focus,Grisys Promax was used to select advanced modules. Key techniques have been studied and tested including involved refraction static correction,deconvolution,remain static correction,migration,DipMoveOut,which provides an effective method to handle the seismic information in this area.
