沙漠地区高精度地震资料处理技术

受静校正及各种类型干扰的影响,西部沙漠地区地震资料的高精度处理较东部地区有更大的难度。对准噶尔盆地中部Ⅱ区、Ⅲ区、Ⅳ区、顺托果勒等区块地震资料在振幅恢复、静校正、去除各类噪音、高精度速度分析及叠前、叠后子波处理等方面进行了大量的试验与研究,形成了较为系统的高精度地震资料处理技术,在西部不同区块地震资料处理中取得了较好的应用效果。

High precision seismic data processing technique in the desert area

Impacted by static correction and different types of noises, it is difficult to process in high resolution seismic da-ta of the west desert area than of the east area. Many tests and studies on aspects, such as amplitude restore, static cor-rection, noise mutting, high precision velocity analysis, prestack and poststack wavelet process, were adopted whileprocessing data got from the middleⅡ, Ⅲ, Ⅳ areas and the Shuntuoguole Block in Zhunger depression. A systematichigh precision seismic data processing technique created by this way was used in the processing of other seismic datagot from the different areas in the west China, and got better results.
