焉耆沙漠低信噪比资料处理方法

Low S/N Data Processing Technique in Zone of Desert in Yanqi

焉耆沙漠区低信噪比资料，按照常规处理方法处理，剖面不能用于地质解释。本文运用“折射交互迭代静校正技术软件包”，成功地解决了沙漠静校正问题；运用线性动校正，结合F－K滤波、地表一致处理、高精度叠加、炮集DMO等手段，最终获得了可用于地质解释的高信噪比剖面。

The seismic sections obtained from the lowsignal-noise ratio data in the zone of desert in Yanqiwith conventional processing techniques are not suitablefor geologic interpretation. We sucessfully solved theproblem of static correction by applying the softwarepackage of refractive interactive static correction technique.High signal - noise ratio sections that can be used forgeologic interpretation are obtained by using the lineardynamic correction technique and combining with F-Kfiltering, surface-consistent processing, highly accuratestacking and cornmon -source - point gather DMO.
