摘要
以合肥盆地低信噪比地震资料为例, 研究了复杂地表区地震资料的处理方法, 总结了一套适合该区地震资料处理的方法与流程, 其中包括了静校正技术、去噪技术、高精度速度分析及动校正修正技术等。通过实际资料的处理证明, 这些技术实用可靠, 效果明显。
Abstract
This paper illustrated processing methods for complex surface seismic data with low signal to noise ratio seismic data from Hefei Basin and proposed a process which consised of statics, noise suppression, high precision velocity analysis, and revision of NMO. Practice showed the process yielded desired results.
